The aim of present paper was to establish the quantitative and qualitative mycological air contamination in educational building of the Faculty of Agriculture and Biology of Warsaw Agricultural University and in the atmosphere outside researched object. Analyses were made using sedimentation and impaction method. The MAS 100 Eco air sampler was used in impaction method. Results of the research made in the indoor and outdoor air showed, that the highest mycological air contamination was in summer and the lowest abundance of fungi was in winter. Taxonomie composition of fungi in the indoor and outdoor air was very similar. In both cases Penicillium, Aspergillus, Cladosporium and Alternaria genuses were dominated.
Przedstawiono badania zanieczyszczenia wód deszczowych odprowadzanych z fermy chowu bydła w Falentach pod Warszawą. Próbki wód były pobierane z dwóch studzienek gromadzących odpływ, z najbliższego rowu i najbliższego cieku. Częstotliwość poboru próbek zwiększano w okresach występowania opadów. Oznaczano odczyn, przewodnictwo, ChZT, stężenie azotu azotanowego, stężenie azotu azotynowego, stężenie azotu amonowego, stężenie fosforanów oraz ogólną liczbę bakterii psychrofilnych, ogólną liczbę mezofilnych, ogólną liczbę grzybów, bakterie redukujące siarczany(IV), bakterie z rodzaju Proteus i miano Coli. Stwierdzono zwiększone wartości ChZT, stężenia fosforanów i wartości niektórych wskaźników mikrobiologicznych w spływie wód opadowych na podwórzu fermy. W okresach występowania deszczu wartości chemicznego zapotrzebowania na tlen i stężenie fosforu przekraczały wartości graniczne dla wód płynących.
The aim of present paper was to establish the quantitative and qualitative mycological air contamination depending on density of people and temperature of the atmospheric air. Anal­yses were made in educational building of Faculty of Agriculture and Biology and in the at­mospheric air outside researched object. These studies showed that higher density of people has a decisive effect on increase of quantity of fungi and their composition — the number of pathogenic fungi is rising then. Research showed that temperature also has a significant influence on microbiological air contamination. It was also found that he higher temperature was, the higher number of fungi contaminated the air.
The paper presents the results of analyse of runoff water from a cattle farm at Falenty near Warsaw, Poland. The water samples came from two wells collecting the outflow, the nearest draining ditch and the nearest stream. The sampling frequency was higher in the rain periods. The reaction, conductivity, COD, concentration of ammonia, nitrite, and nitrate nitrogen, as well as phosphates were determined. Additionally, the total quantity of psychrophilic and mesophilic bacteria, fungi, Proteus sp., sulphide reducing bacteria and the coliform index were also counted. Results showed an increased level of COD and higher concentration of phosphate ions in the rainwater in the area of the farmyard. Relatively high microbiological indexes were also observed. During periods with rain, the values of biochemical demand for oxygen (COD) and concentration of phosphate ions exceeded the thresholds for flowing waters.

Przemiany aniliny w hodowlach bakterii glebowych

63%
During an intensive screening programme, 30 strains of bacteria able to transform of aniline were isolated. The isolated bacteria could transform aniline both under aerobic and anaerobic conditions. On the base of TLC analysis it was possible to observe formation of two main metabolites in culture media of investigated strains of bacteria. These metabolites were named M-l and M-2. It was not possible to isolate the metabolite M-2 from aerobic and anaerobic culture media. The metabolite M-l was isolated from culture medium of strain No 9 growing under aerobic condition. Using Rf value, melting point determination and UV and IR spectra metabolite M-l was identified as a acetanilide. The investigated strain No 9 was classified to generus Bacillus sp. and was the most active in transformation of aniline during growth in Czapek medium at pH 7,0 and incubation temperature 30°C.
Studies were carried out in a 8 years old shelterbelt planted across croplands (D. Chłapowski Landscape Park, region of Wielkopolska, western Poland) and in the easterly adjacent field. The effect of the shelterbelt on: soil organic matter content, soil respiration, microbial biomass, dehydrogenase activity, mineralization potential of N and total number of bacteria and fungi in the upper soil layer was analysed. Samples were collected along parallel sites situated in the central part of the strip (S), in the wood edge (Es), field edge (Ef) and in the field 10 m (F10) and 50 m (F50) away from the strip. All studied microbial parameters, except for plate counted total numbers of bacteria and fungi, showed a high and significant correlation with soil respiration and microbial biomass. The highest values were found in the wood soil, lowest in the field soil and intermediate in the field edge. Marked vertical differences between layers 0-3 and 3-10 cm were noticed on sites S, Es and Ef while stratification in the field was visible not earlier than 11 months after ploughing. Some parameters: soil organic matter contents, dehydrogenase activity, microbial biomass estimated by fumigation-extraction method and mineralization potential of N, showed a regular pattern along the gradient from the shelter-belt to the middle of the field. The study suggests a favourable effect of a shelterbelt on organic matter content in the adjacent field. This effect may increase with age of the wood strip.
