SULFIDOGENIC MICROBIAL COMMUNITIES FROM TECHNOGENICALLY TRANSFORMED SOILS
Journal Title: Мікробіологія і біотехнологія - Year 2016, Vol 0, Issue 2
Abstract
Sulfidogenic microbial communities play a significant role in biogeochemical processes, as well they are one of the biocorrosive relevant agents in man-caused ecotopes. Aim of the study – to investigate the sulfidogenic microbial communities in the soils under different ecological technogenic conditions. Methods. Microbiological, physical chemical and statistical in particular principal component analysis. Results. It is shown that soil from technogenically tranfssormed ecotopes had increasing amount range of sulfate-reducing, iron-reducing and denitrifying bacteria then ones from natural control ecotopes. From 12 studied factors, which were clustered to 4 groups it was identified 5 principal components, described up to 76% of the variations in sulfidogenic microbial communities. Conclusions. The usage of principal components analysis allowed describing the most significant factors which has an influence on the sulfidogenic microbial communities, i.e. quantities of the sulfate-reducing iron-reducing, ammonifying, nitrogen-fixing and denitrifying bacteria, as well as pH, temperature and contain of soluble sulfates.
