Opis:
The aim of the study was to present the dynamics of changes in the number of selected microorganisms in the rhizosphere zone of grasses two years after the application of sewage sludge. The study was conducted on four specially prepared research plots along the main roads in Bialystok. Three doses of sewage sludge were applied: 0 (control), 7.5 and 15 kg/m2. Then the plots were seeded with two mixtures of lawn grasses: Eko and Roadside. Samples of roots with soil were collected three times during the vegetation period of 2012 (April, July and October) and assayed for the total number of bacteria, the number of Gram-negative bacteria, the number of Pseudomonas fluorescens, the number of amylolytic and proteolytic bacteria. Microbiological tests of the rhizosphere showed seasonal variations of all investigated microbiological parameters. The greatest average of the total number of bacteria, Gram-negative bacteria and proteolytic bacteria was observed on the plots in April, amylolytic bacteria in July while in the case of Pseudomonas fluorescens was observed on the plots in October. The time of measurement had the biggest impact on the number of microorganisms. An increased number of microorganisms was observed on all plots in April. Whereas, the fertilization with sewage sludge and grass mixtures did not affect the microbiological parameters.

The aim of this study was to analyse the influence of municipal sewage sludge on selected microbiological parameters in the rhizosphere of lawn grass mixtures. Four experiments on the lawns along the main roads of Bialystok were founded. The factors in the experiment were three doses of sewage sludge (0 – control; 7.5 and 15 kg·m-2) and two grass mixtures (Eko and Roadside). The studied parameters were monitored twice during 2011 vegetation season by determining the total number of soil microorganisms, the total number of Gram-negative bacteria, the number of bacteria of Pseudomonas fluorescens species, the number of amylolytic and proteolytic bacteria. Sewage sludge amended to soil resulted in a change of physical-chemical properties of soil. The sewage sludge application to soil influenced significantly the number of proteolytic and Gram-negative bacteria.

Opis:
Rhizosphere is a region of the strongest interactions be- tween plants, soil and microorganisms, which play an important role in plant development. Due to a number of interdependencies, they are main factors determining the health and proper growth of plants. All methods used in agriculture that promote the growth of microbial populations and their biodiversity are beneficial both for cultivated plants and for the environment. Thuja occidentalis cv. Brabant, is a very popular plant in Poland. In the study the effect of mineral fertilizers: Urea, Polifoska 6, Super Fos Dar 40, enriched with beneficial strains of fungi and bacteria, on selected groups of soil microorganisms was evaluated. The fungi Asper- gillus niger and Purpureocillium lilacinum and bacteria Bacillus sp., Bacillus amyloliquefaciens, Paenibacillus polymyxa, which have been shown to have beneficial effects on plant growth in previous works, have been used as additives to bio-fertilizers. The use of mineral fertilizers Urea, Polifoska 6 and Super Fos Dar 40, enriched with selected strains of fungi and bacteria had a beneficial effect on the development of microorganisms in the rhizosphere of the Thuja occidentalis, especially in the second year of research.

Opis:
Studies conducted in the years 2014-2015 were designed to evaluate of soil fertility from 22 organic farms specializing in the cultivation of strawberries and raspberries from the south-eastern Poland. Evaluated soil sampled in 56 different plantation of strawberries and raspberries. Soil pH was determined in distilled water (pHH2O). Soil fertility determined in the extract of 0.03 M CH3COOH and the content of available forms of nitrate nitrogen (N-NO3), phosphorus (P-PO4), potassium (K), calcium (Ca) and magnesium (Mg) were expressed in mg dm-3 as well as in mg 100g-1 dry soil. In addition in soil samples salinity was determined expressed as g NaCl dm-3. Analysis of the results obtained in the studies showed that the pH of the soils studied (pHH2O) was in the range 4.60-7.60. The content of macronutrients in the soils contained in compartments (mg dm-3): ˂10.0-19.8 N-NO3, 2.0-33.0 P-PO4, 10.0-239.0 K, 107.0-3930.0 Ca, 26.0-134.0 Mg.
Badania przeprowadzone w latach 2014-2015 miały na celu ocenę zasobności gleb w 22 gospodarstwach ekologicznych specjalizujących się w uprawie truskawki i maliny, zlokalizowanych w południowo-wschodniej Polsce. Badaniom poddano 56 prób glebowych z plantacji truskawki i maliny. Odczyn gleby (pH) oznaczono w wodzie destylowanej (pH H2O). Zasobność gleby określano w ekstrakcie 0,03 M CH3 COOH, a zawartości dostępnych form azotu azotanowego (N-NO3), fosforu (P-PO4), potasu (K), wapnia (Ca) i magnezu (Mg) wyrażono w mg∙dm-3, jak również w mg∙100g-1suchej gleby. Ponadto w próbkach glebowych określono poziom zasolenia wyrażony jako g NaCl dm-3. Analiza wyników uzyskanych w badaniach wykazała, że odczyn badanych gleb (pH H2O) zawierał się w zakresie od 4,60 do 7,60. Zawartość makroskładników w badanych próbkach gleb zawierała się w przedziale (mg∙dm-3): ≤10,0-19,8 N-NO3, 2,0-33,0 P-PO4, 10,0-239,0 K, 107,0-3930,0 Ca, 26,0-134,0 Mg.

The aim of this work was to investigate the influence of fresh and thermally treated sewage sludge on the amylolytical activity of the urban soils. Two experimental areas on the lawns along the main roads of Bialystok were prepared in 2011 and 2015. The factors taken into account in the experiment involved: the type of sewage sludge (mechanically dewatered – SS and thermally dried “Granbial” – G), three doses of sewage sludge (0 – control; 14.5 and 29 t DM/ha) and two grass mixtures (Eko and Roadside). The number of amylolytic bacteria in grass mixtures and rhizosphere and amylase activity in soil were monitored twice during 2011 and 2012 vegetation season (in July and October). The main properties of soil (soil pH, granulometric composition, total organic carbon – TOC, available phosphorus and total nitrogen content) after the application of organic substrates were also analysed. Addition of the dewatered sewage sludge to soil resulted in an increase in the number of amylolytic bacteria (from 7.4 to 18.8 ∙106 cfu/g DM) in July, while in the soil treatment with thermally dried sludge, the increased number of the bacteria (from 11.03 to 44.68 ∙106 cfu/g DM) was observed in October. The amylases activity in the soil treated with SS exhibited the highest average value in July (2.11 mg Glc/g DM ∙24 h), while in the soil treated with “Granbial”, it was stable in studied period (from 1.65 to 2.18 mg Glc/g DM ∙24 h).

Mycorrhizal fungi influence the development and activity of communities of soil microorganisms. The purpose of this study was to estimate the effect of arbuscular mycorrhizal fungus Claroideoglomus etunicatum (W. N. Becker & Gerd.) C. Walker & Schüβler on the population structure of fungal colonies in the rhizosphere of tomatoes grown in a plastic tunnel. The field experiment was conducted from 2015 to 2017 at an ecological farm in Grądy, central eastern Poland. The object of study were the three tomato cultivars: ‘Antalya F 1 ’, ‘Esmira F 1 ’, and ‘Pelikan F 1 ’. Tomato seedlings were inoculated with C. etunicatum; spores were introduced about 5 cm deep in the rhizosphere of the studied plants (25–30 spores of C. etunicatum for each plant). Each year, mycological analysis of the tomato rhizosphere was conducted using Warcup’s method; structure of fungal communities of the tomato rhizosphere varied depending on the AMF applied. Saprotrophic fungi such as Trichoderma ssp., Mucor spp., and Penicillium spp. were often more isolated from the rhizosphere of plants inoculated with C. etunicatum than that of the control samples. It can be concluded that AMF directly impacted the development of fungal biodiversity in the tomato rhizosphere, particularly regarding the number of saprotrophs in the soil.

The aim of the study was to determine the effect of various biopreparations on the growth of the apple root system, the number of spores of AMF, the total number of bacteria and microscopic fungi in the rhizosphere soil, and the degree of mycorrhizal association in the roots of two apple tree cultivars. The experiment was established in the spring of 2009 in the Experimental Orchard of the Institute of Horticulture in Dąbrowice. The research objects were one-year-old maidens of the apple cultivars ‘Topaz’ and ‘Ariva’ grafted on M26 rootstock. The trees were treated with the following biopreparations: control, control NPK (standard NPK fertilization), manure, Micosat F + manure, Humus UP, Humus Active + Aktywit PM, BioFeed Amin + manure, BioFeed Quality + manure, Tytanit + manure, Vinassa + manure, Florovit Eko, and Florovit Pro Natura. Treatment of ‘Topaz’ and ‘Ariva’ apple trees with the biopreparations Micosat F, Humus UP, Humus Active + Aktywit PM, BioFeed Amin, Vinassa, Florovit Eko and Florovit Pro Natura produced positive effects on the growth of apple roots and their mycorrhizal frequency, and the size of the populations of microorganisms in the rhizosphere soil.
Celem badań było określenie wpływu różnych biopreparatów na wzrost systemu korzeniowego, liczbę zarodników grzybów mikoryzowych, ogólną liczbę bakterii i grzybów mikroskopowych w glebie rizosferowej oraz stopień asocjacji mikoryzowej w korzeniach dwóch odmian jabłoni. Doświadczenie założono wiosną 2009 r. w Sadzie Doświadczalnym Instytutu Ogrodnictwa w Dąbrowicach. Obiektem badań były jednoroczne okulanty jabłoni odmian Topaz i Ariva szczepione na podkładce M26. Rośliny traktowano następującymi biopreparatami: kontrola, kontrola NPK, obornik, Micosat F + obornik, Humus UP, Humus Active + Aktywit PM, BioFeed Amin + obornik, BioFeed Quality + obornik, Tytanit + obornik, Vinassa + obornik, Florovit Eco oraz preparat Florovit Pro Nature. Traktowanie drzew jabłoni ‘Topaz’ i ‘Ariva’ biopreparatami Micosat F, Humus UP, Humus Active + Aktywit PM, BioFeed Amin, Vinassa, Florovit Eco oraz Florovit Pro Nature wpłynęło korzystnie na wzrost korzeni, stopień frekwencji mikoryzowej i wielkość populacji mikroorganizmów w glebie rizosferowej.

Opis:
Dla roślin wprowadzanych na tereny trudno odnawialne – zalesienia porolne, stanowiska poprzemysłowe czy gleby zdegradowane, znaczącą rolę odgrywają grzyby mikoryzowe i bakterie wspomagające. Pomocne dla stanowisk pozbawionych naturalnych komponentów biotycznych są, stosowane coraz częściej, sztuczne szczepionki mikoryzowo-bakteryjne. Ich efektywność zależy w dużej mierze od gatunków, a raczej szczepu grzyba i bakterii aktywnych w procesie symbiotycznym. Znaczenie ma także pochodzenie mikroorganizmów używanych do mikoryzacji. Oporność grzybów nawet tego samego gatunku na wysokie stężenia metali ciężkich jest większa, gdy izolowane są z terenów skażonych, a efektywność w dostarczaniu wody i soli mineralnych roślinom wzrasta, gdy symbionty pochodzą ze stanowisk suchych. Efektywne zalesienie czy zadrzewienie trudnoodnawialnych stanowisk bez pomocy symbiontów jest niemożliwe.
Mycorrhizal fungi and mycorrhization helper bacteria play an important role for plants in the post - agricultural areas and in the degraded land which are under the influence of industrial emissions. The artificial mycorrhizal-bacteria inoculum can be helpful for areas without natural biotic components. Their effectiveness depends largely on the species, but rather a strain of fungus and bacteria, which are active in the process of symbiosis. The origin of the microorganism used in mycorrhization is also significant. Fungal resistance, even of the same species, at high concentrations of heavy metals is higher when they are isolated from contaminated areas, and the efficiency in the delivery of water and mineral salts for the plant is increased when symbionts come from dry position. Effective land rehabilitation and reforestation in the post - agricultural areas are impossible without the help of fungal and bacteria symbionts.

Opis:
Density and diversity of Fusarium species and other fungi associated with rhizosphere and rhizoplane of lentil and sesame plants at three different growth stages were investigated. Sixteen species of Fusarium were isolated from rhizosphere (13 species) and rhizoplane (11) of both plants studied. In lentil, 11 species were recorded from its rhizosphere (9 species) and rhizoplane (8). Fusarium species associated with lentil rhizoplane gave highest number of propagules at the first stage of plant growth while the ones of Fusarium associated with the rhizosphere produced the highest number at the second stage of growth. F. solani was the most common in the three growth stages. In addition, of two growth stages, F. culmorum and F. tricinctum were isolated from the rhizosphere while F. nygamai and F. verticillioides from the rhizoplane. The other species were recorded from only one growth stage of lentil plant. In sesame plants, rhizosphere yielded nine Fusarium species while rhizoplane gave only six from the three stages investigated. Stage I of sesame rhizosphere possessed the highest colony forming units of Fusarium. As the case for lentil, F. solani was the most common species in sesame rhizospere and rhizoplane. F. verticillioides and F. nygamai (in three different growth stages) followed by F. oxysporum and F. tricinctum (in two growth stages) were recorded using the dilution-plate and/or soil-plate methods from sesame rhizosphere soils. Rhizoplane Fusarium species of sesame plants were isolated at the three different growth stages with almost equal number of colony forming units. F. poae came after F. solani in its frequency since it was recovered from two growth stages. Several of the isolated species are well-known as pathogens to many cultivated plants. To the best of our knowledge, three species are recorded here for the first time in Egypt from the rhizosphere (F. acutatum), rhizoplane of sesame plants (F. longipes) and from rhizosphere of both lentil and sesame and rhizoplane of lentil (F. nygamai).

Opis:
The reported study evaluated the feasibility of rhizosphereenhanced phytoremediation in the removal of nitroglycerin (NG), as applied in commercial smokeless powder (SP), from soil. Double base smokeless powder was applied to soil mesocosms at rates of 0, 1, 5 and 10% (w/w). The mesocosms were seeded with oats (Avena sativa) or planted with live sedge plants (Carex vulpinoidea). Composted biosolids (20% w/w) were used as a soil treatment. Mesocosms were sampled at 7, 14, 30, and 60 days after initial planting. Determination of residual soil NG was performed using gas chromatography with an electron capture detector. Both plant species were capable of modest NG uptake (146.0 and 87.5mg·kg-1 for sedge and oat, respectively at the 10% SP rate). Only modest quantities of NG removal were accounted for by abiotic processes such as soil sorption. Soil bacterial numbers remained relatively constant regardless of rate of SP application. Microbial activity in the plant rhizosphere was concluded to be the major contributor to NG solubilization and decomposition. Addition of composted biosolids to soil imparted a positive effect in NG decomposition and/or removal from soil. Additional study is needed to determine long-term decomposition of smokeless powder and subsequent NG reactions in soil.

Opis:
The purpose of the studies carried out in the years 1996-1998 was to establish the composition of bacteria and fungi communities in the potato rhizosphere and non-rhizosphere soil. Besides, in the examined samples the studies established the proportion of bacteria and fungi antagonistic towards soilborne pathogens. The microbiological analysis of 1 g of dry weight of soil coming from the rhizosphere of potato revealed from 3.96 x 10⁶ to 7.26 x 10⁶ bacteria colonies and from 51.38 x 10³ to 69.96 x 10³ fungi colonies. In the case of nonrhizosphere soil of 1 g of dry weight of soil revealed from 3.50 x 10⁶ to 4.75 x 10⁶ bacteria colonies and from 16.16 x 10³ to 34.10 x 10³ fungi colonies. Moreover, potato cultivation had a positive effect on the increase of numbers of antagonistic bacteria (Bacillus spp. and Pseudomonas spp.) and fungi (Gliocladium spp., Penicillium spp., Trichoderma spp.). A larger number of the communities of bacteria and fungi, including antagonistic ones, in the root area of potato, indicates considerable biological activity, which contributes to a better phytosanitary condition of the soil.
W latach 1996-1998 przedmiotem badań była gleba ryzosferowa ziemniaka oraz pozaryzosferowa. Na podstawie analizy mikrobiologicznej uzyskane wyniki wykazały, że w 1 g s. m. gleby ryzosferowej ziemniaka średnia liczebność bakterii oraz średnia liczebność grzybów była większa, aniżeli w glebie pozaryzosferowej. Podobna zależność wystąpiła w przypadku bakterii z rodzaju Pseudomonas. W przypadku bakterii z rodzaju Bacillus o 6% więcej kolonii uzyskano z gleby pozaryzosferowej w porównaniu z glebą ryzosferową ziemniaka. Na podstawie badań laboratoryjnych stwierdzono, że w obrębie zbiorowisk populacji bakterii i grzybów w glebie ryzosferowej opisanej rośliny było znacznie więcej antagonistycznych Bacillus spp., Pseudomonas spp., Gliocladium spp., Penicillium spp. i Trichoderma spp., aniżeli w glebie pozaryzosferowej. Liczebność populacji bakterii i grzybów w strefie przykorzeniowej ziemniaka była większa w porównaniu z glebą pozaryzosferową, co może świadczyć o zwiększonej aktywności biologicznej gleby ryzosferowej.

The purpose of the studies conducted in the years 1996-1998 was to determine the quantitative and qualitative composition of bacterial and fungal communities in rhizosphere of soybean cultivated in monoculture and non-rhizosphere soil. Besides, the proportion of bacteria and fungi, which were distinguished by their antagonistic effect towards soil-borne pathogens was established. A microbiological analysis of 1g of dry weight of soil from rhizosphere of soybean resulted in 3.21 x 10⁶ to 8.70 x 10⁶ bacterial colonies and from 70.51 x 10³ to 123.74 x 10³ fungal colonies. In the case of non-rhizosphere soil, 3.50 x 10⁶ to 4.75 x 10⁶ bacterial colonies and 16.16 x 10³ to 51.38 x 10³ fungal colonies were obtained. Besides, soybean cultivation in monoculture had a negative effect on the number of antagonistic isolates of bacteria (Bacillus spp., Pseudomonas spp.) and fungi (Gliocladium spp., Penicillium spp., Trichoderma spp.). Smaller numbers of antagonistic bacteria and fungi in rhizosphere soil of soybean cultivated in monoculture as compared to non-rhizosphere soil, can prove little biological activity, which results in a worse phytosanitaty condition of the soil.
Przedmiotem badań przeprowadzonych w latach 1996-1998 była gleba ryzosferowa soi uprawianej w monokulturze oraz gleba pozaryzosferowa. Analiza mikrobiologiczna wykazała, że w 1 g s.m. gleby ryzosferowej średnia liczebność bakterii oraz grzybów była większa, aniżeli w glebie pozaryzosferowej. W próbach badanych gleb liczebność bakterii z rodzaju Bacillus była zbliżona. W przypadku bakterii z rodzaju Pseudomonas ogólna ich liczebność była prawie trzykrotnie większa w ryzosferze soi, aniżeli w glebie pozaryzosferowej. Badania laboratoryjne wykazały, że znacznie więcej antagonistycznych Bacillus spp., Pseudomonas spp., Gliocladium spp., Penicillium spp. i Trichoderma spp. wystąpiło w glebie pozaryzosferowej, aniżeli w ryzosferze soi. Mniejsza liczebność antagonistycznych bakterii i grzybów w ryzosferze soi uprawianej w monokulturze może świadczyć o małej aktywności biologicznej mikroorganizmów, co przyczynia się do pogorszenia fitosanitarnego stanu gleby.

Opis:
Fluorescent Pseudomonas (FP) is a major group of plant growth promoting rhizobacteria and a well-known synthesizer of siderophores, which imparts a selective advantage on rhizosphere competence and their biocontrol traits. The present study was aimed at examining the factors affecting the production of siderophores and their potential biocontrol traits. Sixteen FP isolates were shortlisted based on their siderophore-producing ability in chrome azural S medium. The isolates were checked for variations in siderophore production under varying incubation times, temperatures, pH, iron (Fe3+) concentrations and mutagens. In addition, the iron binding affinity of siderophores, mycelial inhibition assay and plant growth promotion traits were assessed. Results showed that the siderophore production was highly influenced by the time of incubation, changes in pH, temperature and iron concentration. Chemical characterization showed that the produced siderophores were hydroxamates. Maximum siderophore production was observed at pH 7 whereas UV and EtBr exposure invariably suppressed siderophore production drastically in all isolates. All FPs from maize rhizosphere showed excellent siderophore production which could be due to the competence in strategy-II of the plant rhizosphere and significant growth inhibition on Fusarium oxysporum. Our results suggest the inclination of siderophores to iron, in terms of various criteria affecting production and the possible role of environmental mutations that affect the natural iron harvesting mechanism.

Opis:
The research areas were selected in the regions heavily polluted by wastes from the former washing plant, flotation waste dump and by non-sulphide Zn-Pb ores from open pit mining in the Olkusz region. The submicroscopic phases occurring in the surface of plant roots and in the rhizospheres were investigated by XRD and SEM/EDS methods. Morphology of submicroscopic metalliferous phases and their manner of occurrence were the subject of study. The analysis of EDS spectra enabled to identify phases and mineral aggregates including Zn, Pb, Fe, Mn, Cd in their structure. The soils from the washing plant and areas of open pit exploitation are contaminated by diverse complexes of minerals. The occurrence of unstable Fe, Pb, Ca sulphates indicate that these wastes are still intensively geochemically active.
