Opis:
A phylogenetic tree shows graphically the evolutionary relationships among various organisms. The dynamic development of molecular biology and bioinformatics has led to a revolution in our knowledge of biological evolution and the kinships between living organisms and viruses. Nowadays, the available laboratory techniques and computer software allow reconstruction of the actual changes which occurred in the evolutionary process. The derivation of molecular evolution models and several methods for building phylogenetic trees have played a huge role in that enterprise. The emergence of new infectious agents is a problem afflicting mankind since prehistoric times. The study of phylogenetic implications among pathogenic microorganisms allows tracking the process of evolution, the indirect understanding of their biology, and thus facilitates the implementation of treatment. The presented article demonstrates the basic methods for constructing phylogenetic trees, as well as the benefits of reconstructing the evolution process and kinship with the study of microorganisms; in particular, viruses are considered from the clinical aspect.

Opis:
W ostatnich latach bardzo duże znaczenie w usuwaniu ksenobiotyków mają metody biologiczne. Wiele gatunków mikroorganizmów występujących w środowisku glebowym ma zdolność do biodegradacji związków ropopochodnych. Ich rozkład jednak zwykle trwa latami. Intensyfikację tego procesu uzyskuje się głównie poprzez biostymulację i/lub wykorzystanie biopreparatów w formie wolnej biomasy lub immobilizowanej na nośnikach, takich jak alginian, akrylan czy karagen. Aktywność degradacyjna mikroorganizmów zależy od bioróżnorodności środowiska oraz parametrów fizykochemicznych, w tym dostępności związków odżywczych, temperatury, pH czy stężenia tlenu. Z tego powodu podczas bioremediacji bardzo ważnym aspektem jest monitorowanie zmian w składzie związków chemicznych oraz bioróżnorodności zanieczyszczonego środowiska. W artykule przedstawione zostały informacje na temat typów bioremediacji, wpływu czynników fizykochemicznych na efektywność rozkładu ksenobiotyków oraz metody monitorowania przemian związków chemicznych i dynamiki populacji mikroorganizmów w glebie.
In the recent years the demand for petroleum and products associated with its processing, which contributes to the progressive contamination of the environment, has greatly increased. Crude oil consists primarily of hydrocarbons, such as alkanes, cycloalkanes, aromatic hydrocarbons, and polycyclic aromatic hydrocarbons (PAHs). Bioremediation is a technique that combines achievements of microbiology and microbial ecology, biochemistry, genetics and chemistry. Xenobiotics may be removed in the place of contamination (in situ) or preceded by the transfer of contaminated soil from its natural area (ex situ). Many species of microorganisms found in the soil are capable of biodegradation of petroleum compounds. However, the natural biodegradation of petroleum compounds in soil usually takes a long time. The intensification of this process is achieved primarily by biostimulation and/or bioaugmentation. The first method is based on environmental enrichment in nutrients and ensuring optimal environmental conditions (temperature, pH, oxygen concentration). Bioaugmentation relies on the introduction into the environment selected strains of microorganisms capable of degrading xenobiotics in free cells form or immobilized biomass on carriers, such as alginate, acrylate, or carrageenan. Microbial degradation activity depends on biodiversity and physicochemical parameters, including the availability of nutrients, temperature, pH, and oxygen concentration. For this reason, during the bioremediation, a very important aspect is to monitor the changes in the chemical composition of the contaminated environment and the soil biodiversity. Nowadays, we have many laboratory techniques to identify microorganisms. Phenotypic methods include e.g. fatty acid analysis, cell wall structure, the enzyme activity or substrate utilization profile. One of the disadvantages in the analysis of the phenotype is that the full information contained in the genome is never expressed, because it is directly related to the environmental conditions (e.g. growth conditions in the laboratory). Nucleic acid is an excellent tool to study because it is characteristic of all living organisms. For this reason, the molecular biology methods are increasingly used for the identification of microorganisms (such as PCR, hybridization, sequencing, metagenomics). The article presents information about the types of bioremediation, the impact of physical and chemical factors on the efficiency of the xenobiotics decay and methods of monitoring of chemical transformations and dynamics of microorganisms populations in the soil.

Opis:
The laboratory experiment was carried out in 2008-2009. It consisted of several series of measurements, which were designed to evaluate the effect of magnetized water on seeding value and growth of seedlings and the weight of selected plant species. The results confirmed a diverse reaction of assessed species seeds towards the type of water used. Mag¬netized water stimulated the seed germination of garden savory and rape, while had no effect on the seeds of yellow lupine. In case of the seeds of buckwheat, this parameter decreased under the influence of magnetized water in the first six days of the experiment. A beneficial effect of bio-stim¬ulation with magnetized water on the rate of growth of the aboveground parts of seedlings was recorded. The positive effect related to all species. The greatest stimulation was observed in buckwheat and garden savory. The use of magnetized water reduced the growth rate of roots at garden savory and buckwheat, while it increased the growth of winter rape roots. It had no effect in yellow lupine. The type of water exerted a significant influence on the fresh weight and roots of seedlings. Regardless of the assessed species, the use of magnetized water resulted in a significant increase in fresh weight and roots by 6% and 9%. No significant influence of the water type on dry matter of seedlings of analysed plant was assessed.

Opis:
The aim of the study was to determine the influence of microirrigation (microjet sprinkling and drip irrigation) and organic fertilization (compost prepared on the base of sewage sludge) on a seedling vigour of one-year and two-year old Scot pine seedlings (Pinus sylvestris L.), cultivated on a post-agricultural ground with the use of zoo-melioration in two different regions. Field experiments were carried out on an experimental field in Kruszyn Krajeński (loose sandy soil of quality class VI) near Bydgoszcz and in Lipnik near Stargard Szczeciński (sandy soil of quality class IVb). The first row factor was irrigation used in three treatments: without irrigation (control), drip irrigation, microjet sprinkling. The second row factor was fertilization, used in two variants: mineral fertilization (standard applied in forest nurseries), organic fertilization (compost). The irrigation significantly increased the height and the diameter of the Scot pine seedlings. There were no significant differences in the characters of the growth between the two irrigation systems. Fertilization of Scot pine seedlings with the compost increased significantly the height of seedlings. Interaction of irrigation with organic fertilization of Scot pine seedling height and diameter was noted. Pine seedlings grown on the plots fertilized with compost under irrigation conditions were characterized by increased height and diameter. Better effects were obtained in Lipnik than in Kruszyn Krajeński. Joint effect of organic fertilization and microjet sprinkling positively influenced the density and the species number of Oribatida in Kruszyn Krajeński. The obtained results indicated that the amelioration measures used can positively influence the growth of Scot pine seedlings on a post-agricultural ground.

Opis:
The aim of the study was to determine the effect of drip irrigation on yielding of summer squash ‘White Bush’ grown under conditions of two localities: Lipnik near Stargard Szczeciński (soil of quality class IVb, and of good-rye-soil-complex) and Kruszyn Krajeński near Bydgoszcz (soil of quality class V, and of weak-rye-soil-complex). The study was designed as one-factorial trial: drip irrigation as the experimental factor was considered. Drip irrigation was conducted according to soil tensiometer indications (-0.04 MPa). Both, in Lipnik as well as in Kruszyn Krajeński, drip irrigation significantly increased marketable yield of summer squash ‘White Bush’. A higher rise in yields due to irrigation was obtained in Kruszyn Krajeński than in Lipnik. Mean marketable yield of summer squash fruits in Lipnik was higher than that obtained in Kruszyn Krajeński. Drip irrigation significantly increased the single fruit weight in relation to the control, in both crop localities. The system of drip irrigation significantly affected the number of fruits per plant. Summer squash plants grown in Lipnik produced higher number of fruits, than in Kruszyn Krajeński. In addition, essential influence of drip irrigation was affirmed on chemical composition of fruits, i.e. dry matter, vitamin C, monosaccharides, saccharose, content of total sugars and sum of carotenoids and ß-carotin.

Opis:
The aim of the study was to determine the influence of mulching and organic fertilization on the seedling vigour of Scots pine and occurrence of soil mites (Acari) in forest- and post-arable soils. Two different field experiments were carried out in the vegetation period of the year 2005 on light soils at two different sylvan-natural regions. The first trial was conducted at Białe Błota near Bydgoszcz – on a brown podzolic soil. The second experiment – at Lipnik near Stargard Szczeciński – on an acid brown soil. The experiments were run in a split-plot system with four replications. Two different factors were compared. The first row factor was fertilization, used in the two following treatments: N1 – treated sewage sludge (⅔) + bark (⅓) and N2 – treated sewage sludge (⅔) + sawdust (⅓). The second row factor was mulching, used in the two variants: C – without mulching (control) and S – mulching with litter. Scots pine seedlings grown on the forest soil at Białe Błota were characterized by increased height than those cultivated on the post-arable land at Lipnik. The best results, both on the forest soil as well as on the post-arable ground, were obtained in the case of treatment SN1 (plots mulched with litter and fertilized with treated sewage sludge (⅔) with bark admixture (⅓)). The higher was the rainfall amount during the vegetation period, the lower was the seasonal irrigation rate supplied to the Scots pine seedlings. Because of this the seasonal irrigation water rate applied at Białe Błota was higher than that at Lipnik. Fresh mass of the above-ground parts of the Scots pine seedling was higher on the forest soil as compared to that on the post-arable land. The seedlings grown on the treatments mulched with litter were characterized by higher root mass in comparison to those on the control plots (without mulching). Mulching with litter influenced the general number of mites, the number of oribatid mites as well as their species diversity. Organic fertilization (treated sewage sludge with bark or with sawdust) did not influence these indices.

Opis:
The ash-leaved maple (Acer negundo L.) has low habitat requirements, which is why this species is often used in the reclamation of industrial areas. The development of the reclamation plantings depends on the optimal water soil conditions that can be controlled by watering treatments. However, the use of irrigation requires determining the water needs of the cultivated species. The objective of the study was to evaluate the water needs of the ash-leaved maple in the reclamation plantings, in the period of over three years after planting. The water needs of the ash-leaved maple were determined using the crop coefficients method. Potential evapotranspiration was calculated using the Blaney-Criddle’s formula that was modified for the Polish conditions by Żakowicz. The water needs of the ash-leaved maple were assessed for five agro-climatic regions of Poland, in the years 1981-2010. The water needs of the ash-leaved maple in the growing period (April-October) were the highest in the C-E (638 mm) and C-N-W (637 mm) regions, and the lowest in the N-E (598 mm) and S-E (601 mm) regions. In July, the highest water needs were noted in the C-N-W region (149 mm) and the lowest in the S-W region (129 mm). In the studied thirty-years period, there was a significant upward trend in the water needs of the ash-leaved maple both during the growing season (except for the C-N-W region) and in July, in all the considered regions.
