Opis:
White rot disease caused by Sclerotium cepivorum is a major yield reducing fungal disease of garlic found throughout the world, including Iran. The use of chemical fungicides is the most common control method for the disease at the present time. This control measure is costly, contaminates the environment, and harms non-target organisms. Moreover, since the pathogen is soil-borne, chemical control strategy is not quite effective against the disease. In this study, we tried to develop and prepare some new bioformulations based on three antagonistic fungal species: Trichoderma harzianum, T. asperellum, and Talaromyces flavus. Six isolates of the abovementioned fungi were used along with the organic and inorganic carriers, rice bran and talc, to develop twelve new bioformulations. The effectiveness of the bioformulations were then evaluated in the control of garlic white rot disease in the greenhouse conditions in comparison with the healthy control, infected control, and the commonly used fungicide Carbendazim. The design of the experiment was completely randomised. There were 15 treatments each, with four replicates. The results of the greenhouse experiments indicated that almost all the developed bioformulations resulted in significant reductions (34.50 to 64.50%) in the incidence of white rot disease. In general, bioformulations which contained the organic carrier (rice bran) performed more effectively than those that contained the inorganic carrier (talc). Bioformulations which contained an organic carrier (rice bran) were as effective as the fungicide Carbendazim.

Opis:
Three species of white rot fungi: Cerrena unicolor, Phlebia lindtneri and Pycnoporus sanguineus were cultured in two different media under five different lighting conditions: dark, white, red, blue, and green light. Laccase, cellobiose dehydrogenase, and protease activities were examined in the samples. Blue light efficiently boosted laccase synthesis in C. unicolor and P. sanguineus, whereas the highest activities (20 654 nkat/l) of P. lindtneri laccase were observed when this fungus was maintained in green light. On the contrary, the green light allowed obtaining the highest activities of cellobiose dehydrogenase of C. unicolor and P. lindtneri, while CDH of P. sanguineus seems to be dependent on white light. It is clearly visible that differences in protease activities are noticeable not only between the lights variants but also among the media used. However, high proteases activities are correlated with light variants inducing laccase in Lindeberg and Holm medium. Contrary to the cellulose-based medium, where they are weak in light variants that lead to high CDH activities.

Opis:
The effect of supplementation of medium with rapeseed meal (RM) on production of biotechnologically important enzymes was investigated in submerged cultures of the white rot fungus Cerrena unicolor. The addition of RM (3.5% w/v) distinctly stimulated the activities of laccase, chitinase, and β-glucosidase. As compared to the control, the activities of chitinase, β-glucosidase, and laccase in the RM supplemented cultures were up to 4.1, 8.4, and 3.9 times higher, respectively. The results of the spectrophotometric and spectrofluorometric measurements were additionally confirmed by zymographic analysis of the samples. The level of sugars and phenolic compounds as well as the antioxidative ability of fungal preparations were also determined. The results obtained indicate that the submerged liquid fermentation of rapeseed meal can be proposed as an inexpensive and very effective method for biotechnological production of chitinase, β-glucosidase, and laccase by C. unicolor.

Opis:
The white rot fungi (WRF) isolated from the plantation and natural forests of Arsi forest enterprise (Dagaga and Gambo sites) were screened for their ligninolytic potentials and their Laccases were quantitatively determined. The fungi were grown in both submerged fermentation (SmF) and solid state fermentation (SSF) of wheat bran (WB) and sawdust of Eucalyptus grandis (sawdust). The activities of Laccases of the fungal isolates were quantified and their productions were optimized. Quantification of Laccases indicated that the fungal isolates secreted their highest enzymes on the 8th day of SmF and on 12th day of SSF in WB and sawdust substrates. Laccase activities of SSF were higher than Laccase activities of SmF in both growth substrates. The highest Laccase activities of 0.345 U/ml and 0.379 U/ml were obtained during SmF and SSF of WB, respectively, by isolate 003-2G. Laccase activities of 0.430 U/ml and 0.446 U/ml were also obtained while SSF of sawdust by the same isolate. Laccase quantification data indicated sawdust to be more suitable than WB for Laccase production. 45 °C was most optimum for the Laccase activities and the enzyme was stable in the temperature range of 40-45 °C. It was also found that the Laccases of the fungi were active and stable at pH 5.0. Optimization experiments also revealed that production of Laccases from the fungal isolates can be maximized by adjusting the fungi cultivation conditions and supplementations of the growth media.

Opis:
Związki nitrowe to szeroka grupa ksenobiotyków, które ze względu na swoją silną toksyczność, wyjątkową odporność na rozkład biologiczny oraz skłonność do bioakumulacji, stanowią bardzo poważny problem dla biosfery. Prowadzi się obecnie wiele badań nad mikroorganizmami, które zdołały wykształcić szlaki metaboliczne pozwalające na rozkład takich związków jak 2,4,6-trinitrotoluen, kwas pikrynowy czy kwas 3,5-dinitrosalicylowy. Jednym z takich mikroorganizmów jest podstawczak Phanerochaete chrysosporium, należący do grupy grzybów białej zgnilizny drewna. Artykuł ten poświęcony jest badaniom nad rozkładem kwasu 3,5-dinitrosalicylowego przez P. chrysosporium w warunkach hodowli stacjonarnej w pożywce zawierającej 0,05–0,5% masowego kwasu 3,5-dinitrosalicylowego. Uzyskane wyniki wskazują na zdolność wybranego mikroorganizmu do rozkładu substratu na drodze redukcji grup nitrowych.
Despite intensive efforts put on prevention of environment pollution by nitroaromatic compounds, these xenobiotics have not been eliminated from the biosphere. The physicochemical properties make nitroaromatics extremely recalcitrant to biodegradation. Therefore, microbial degraders of these pollutants are sought after. This paper reports preliminary results of the study on degradation of 3,5-dinitrosalicylic acid (DNS) by a basidiomycetous fungus Phanerochaete chrysosporium under stationary conditions in a culture medium containing 0.05–0.5% v/v of DNS. The results obtained suggest that the fungus degrades DNS through the reductive pathway.

Opis:
Grzyby wykazują wiele cech przydatnych w inżynierii środowiska, dających im przewagę nad bakteriami. Udowodniono, że potrafią one rozkładać wiele skomplikowanych związków organicznych, także ksenobiotyków, takich jak trudnobiodegradowalne wielopierścieniowe związki aromatyczne, polichlorowane węglowodory, dioksyny, pestycydy oraz pozostałości materiałów wybuchowych. Ważną rolę w naturalnej regulacji liczebności populacji roślin odgrywają pasożytnicze gatunki grzybów, a gatunki symbiotyczne są niezbędne do prawidłowego rozwoju i wzrostu wielu gatunków roślin. Ich różnorodność taksonomiczna, genetyczna i funkcjonalna jest ogromna i stanowi obszerne źródło organizmów użytecznych w procesie bioremediacji. W dokonanym przeglądzie piśmiennictwa wykazano, że różne gatunki grzybów mogą znaleźć zastosowanie w remediacji środowiska gruntowo-wodnego oraz w oczyszczaniu ścieków i gazów odlotowych. Jednakże dotychczasowe badania nad wykorzystaniem grzybów najczęściej były prowadzone w skali laboratoryjnej. Eksperymenty w skali półtechnicznej i polowej wykazały, że na obecnym etapie praktyczne wykorzystanie grzybów w systemach inżynierii środowiska nie jest ekonomicznie uzasadnione. Problemem, który wymaga rozwiązania jest utrzymanie dominacji szczepów grzybów o wysokiej aktywności degradacyjnej w otwartych układach oczyszczających w warunkach konkurencji ze strony mikroorganizmów autochtonicznych. Duże nadzieje wiąże się z jednoczesnym wykorzystaniem w układach oczyszczania środowiska grzybów i bakterii, których skuteczność biodegradacyjna może się wzajemnie uzupełniać. Aby w pełni wykorzystać specyficzne walory grzybów niezbędne są badania przesiewowe w celu izolacji szczepów o szerszych zdolnościach metabolicznych, a także udoskonalanie szczepów metodami in vitro. Podobnie przyszłościowe jest wykorzystanie w bioremediacji immobilizowanych enzymów grzybowych. Rozwój technik molekularnych pozwoli na zmniejszenie nadal jeszcze wysokich kosztów wytwarzania, oczyszczenia i immobilizacji enzymów na odpowiednich nośnikach.
Fungi possess many features useful to environmental engineering, which gives them an advantage over bacteria. Their ability to decompose many complex organic compounds, including xenobiotics, such as difficult to biodegrade polycyclic aromatic compounds, polychlorinated hydrocarbons, dioxins, pesticides and explosive residues has been documented. Parasitic fungi species play an important role as natural regulators of plant population size, while symbiotic species are essential to proper development and growth of many plant species. The enormous taxonomic, genetic and functional diversity of fungi constitutes a rich source of organisms useful in bioremediation process. The literature review demonstrated that various types of fungi could be employed in remediation of soil-water environment as well as in treatment of wastewater and waste gases. However, most often current studies on fungal applications are carried out on a laboratory scale. At the current stage, as demonstrated by semi-technical and field-scale experiments, practical use of fungi in environmental engineering systems is not economically justified. Maintenance of dominance of fungal strains with high degradation activity in open purification systems in competition with indigenous microorganisms remains an open problem. Great promises are held out for simultaneous use of fungal and bacterial environments in treatment systems, as their biodegradation effectiveness may complement each other. Improvement of strains by the in vitro methods and screening tests to isolate strains with broader metabolic abilities are necessary in order to take full advantage of the specific benefits of fungi. Similarly, use of immobilized fungal enzymes in bioremediation offers good prospects for the future. Development of molecular techniques will allow for reduction of persistently high costs of enzyme production, purification and immobilization on appropriate carriers.

Opis:
Black alder is an important forest−forming species in Poland. Its wood is decomposed by many species of fungi. Ganoderma lucidum (Curtis) P. Karst. is a species of Basidiomycetes which belongs to family Ganodermataceae, order Polyporales. This fungus causes white rot decay of wood in dead and sometimes living alder trees. G. lucidum has been under partial protection in Poland since 2014. It is also red−listed as a rare species (category R – taxa with small populations) on the ‘Red list of the macrofungi in Poland’. The fungus was cut out with a sizeable fragment of wood from the alder stump in Łuków Forest District (eastern Poland) and transported to the laboratory of the Department of Mycology and Forest Phytopathology, Warsaw University of Life Sciences−SGGW. Pure culture of G. lucidum mycelium was obtained from a fragment of fruitbody. The aim of this study was to investigate, through laboratory decay tests, the ability of G. lucidum to degrade alder wood. Sterilization of wood samples (30×20×20 mm) consisted of placing the material in an accelerator and irradiating it with high−energy electrons at a dose of 30 kGy at the Institute of Nuclear Chemistry and Technology in Warsaw. On the next day, wood samples were put into 200 ml flasks with mycelium of G. lucidum on agar−wort medium (2 samples per flask). The flasks were placed in a Heraeus BK 600 incubator for 180 days, with a constant temperature of 22°C and humidity of 80 ±5%. Every 30 days 10 flasks were randomly selected, i.e. 20 samples of alder wood from this experiment. After each incubation period the samples were removed from the flasks, cleaned to remove mycelia and dried at a temperature of 105°C until they reached constant weight. By comparing mass of the samples at the start and the end of experiment in an absolutely dry state, the relative wood mass loss was calculated. After exposure times 180 days, the relative weight loss of alder wood as a result of decay by G. lucidum mycelium was on average 10.88%. The rate of the decay was almost constant during the study period. On some alder wood samples structures resembling fruitbodies of G. lucidum were noticed.

Opis:
The effect of Phlebiopsis gigantea treatment in control of Heterobasidion parviporum in Norway spruce is less effective than that in control of Heterobasidion annosum in pine. It is necessary to apply other fungi, for example, Pleurotus abieticola in Norway spruce stands. Thus, it is necessary to assess the activity of major ligninolytic enzymes, that is, laccase, lignin peroxidase (LiP), manganese peroxidase (MnP) and versatile peroxidase (VP) produced by P. abieticola, which may be effective in the fast degradation of Norway spruce wood. Three strains of P. abieticola (Pa1-3) were grown on pieces of Norway spruce sapwood and heartwood for 50 days in laboratory conditions. Enzymatic activity was determined using spectrophotometry. Pleurotus abieticola produced laccase, LiP, MnP and VP. The activity of laccase was low, ranging 0–3.696 and 0–0.806 mU/μg of protein in sapwood and heartwood, respectively. The highest activity in Pa1 = 3.696 mU/μg of protein in sapwood and in Pa3 = 0.806 mU/μg of protein in heartwood was observed after 30 and 50 days of incubation, respectively. The activity of LiP was also low, ranging 0–0.188 and 0–0.271 mU/μg of protein in sapwood and heartwood, respectively. The highest activity in Pa1 = 0.271 mU/μg of protein in sapwood and in Pa2 = 0.188 mU/μg of protein in heartwood was observed after 40 and 20 days of incubation, respectively. The activity of MnP ranged 0–17.618 and 0–12.203 mU/μg of protein in sapwood and heartwood, respectively. This enzymatic activity peaked at the 50th day of culture on sapwood for the Pa3 strain (17.618 mU/μg of protein) and at the 20th day of culture on heartwood for the Pa1 strain (12.203 mU/μg of protein). The activity of VP with manganese-oxidising properties was found to be high in all strains of P. abieticola, ranging 0–39.19 and 0–59.153 mU/μg of protein in sapwood and heartwood, respectively, whereas the activity of VP with guaiacol-oxidising properties was very low for all P. abieticola strains, ranging 0–0.248 and 0–0.225 mU/μg of protein in sapwood and heartwood, respectively. The values of released hydroxyphenols in P. abieticola strains ranged 24.915–139.766 and 25.19–84.562 µg of protocatechuic acid/ml in sapwood and heartwood, respectively. The values of released methoxyphenols for the evaluated strains of P. abieticola ranged 7.225–23.789 and 1.953–20.651 µg of vanillic acid/ml in sapwood and heartwood, respectively. Further studies with a higher number of strains of this species as well as an optimisation of conditions for the measurement of ligninolytic activity are needed.

Opis:
The paper reports the laboratory research on the natural wood resistance against white pattern fungal wood decomposition. Wood samples of 25, both European and exotic, tree species were collected and used (tab. 1). All samples were dried and weighted, then put on the mycelium of four different white rot causing fungi species: Fomes fomentarius ((L.: Fr.) Kickx), Schizophyllum commune (Fr.: Fr.), Stereum hirsutum ((Willd.: Fr.) Gray) and Trametes versicolor ((L.: Fr.) Pilát). After 30, 60 and 90 days of exposition the samples were put out, cleaned, dried and weighted again. The weight loss indicated the range of wood decomposition and allowed to estimate its natural resistance against fungal wood decay. The results showed that in laboratory conditions the range of all fungi species trophic abilities were much wider than the one observed in nature. Examined fungi were able to destroy wood from trees they never occur on. The reasons of this could be both mechanical (the absence of bark – natural barrier for fungi) and chemical (the less of chemical substances occurring in wood of living trees that could be responsible for its natural resistance against fungi).

Opis:
The capacity of five white rot fungi species to degrade linuron, metribuzin and chlorpyrifos when applied both as single pesticides and mixed together in different concentrations on nutritionally poor media was investigated. Our results suggested that Pleurotus ostreatus, Pycnoporus coccineus, Phlebiopsis gigatea and Τrametes versicolor showed a remarkable tolerance to the pesticides, in all media tested. The EC50 values presented a noticeable difference in the mixtures as compared with the individual ones. The minimum growth rate in the mixture was obtained by P. ostreatus whereas P. coccineus appeared to be more efficient than the rest fungal isolates, when cultivated in the soil extract medium. P. coccineus, P. gigantea and T. versicolor produce high levels of polyphenol oxidase, but only T. versicolor was capable of decomposing linuron when combined with metribuzin and chlorpyrifos.
