THE TEMPERATURE INFLUENCE ON THE STRUCTURE OF MICROBIAL COMMUNITIES OF BOG PEATLAND (MODEL EXPERIMENT) // Tomsk State Pedagogical University Bulletin. 2010. Issue 3 (93). P. 92-100

In the annual model experiment was made the monitoring of quantity and taxonomical structure of the bacterial and fungal complexes in the monoliths of the bog peatland under temperature of20-24 oC and 4-6 oC, using the fluorescent- microscopic and plate methods. It was established, that low temperatures didn't exert serious influence on the morphological, taxonomical structure and abundance levels of the fungal complexes. The temperatures stimulated the development of Basidiomycetes and dark-coloured mycelium. Among the bacterial hydrolytic complex, Bacillus were the most adapted to the low-temperature conditions. In the bog peatland, fungi were shaped as mycelium, and spore-forming bacteria were shaped as vegetative cells, that's why they occurred to be in an active state. Also the fungi and spore-forming bacteria were adapted to low-temperature conditions and that helped them to decompose vegetative polymers.
