DYNAMICS OF BIOCHEMICAL ACTIVITY AND GAS REGIME OF EUTROPHIC BOG // Tomsk State Pedagogical University Bulletin. 2012. Issue 8 (123). P. 187-191

Results of enzyme activity and mode of gas (carbon dioxide and methane) in peat deposits of eutrophic bog in climatic conditions in 2011 year are described in the article.

Keywords: peat deposit, enzymes, biochemical activity, gas regime

BIOLOGICAL ACTIVITY OF PEAT DEPOSIT TUROCHAK BOG // Tomsk State Pedagogical University Bulletin. 2013. Issue 8 (136). P. 131-136

The results of the investigation of biological activity of eutrophic peat deposits Turochak bog are presented in the article. Microbial biomass and enzymes activity (catalase, invertase), which characterize the basic biochemical properties, are estimated. Concentration of microbial biomass was recorded to decrease as the degree of decomposition and reduce light-hydrolyzing substances. Peat deposit Turochak bog full-depth biological activity.

Keywords: bog, peat deposit, biological activity, microbial biomass, enzymes, catalase, invertase

DYNAMICS OF MICROBIAL BIOMASS OF THE OLIGOTROPHIC BOG // Tomsk State Pedagogical University Bulletin. 2013. Issue 8 (136). P. 143-148

The method of substrate-induced respiration studied the dynamics of the rate of basal respiration, microbial biomass and metabolic quotient peat deposits oligotrophic bog (north-eastern part of the Vasyugan bog). It was determined that on average during the season microbial biomass values vary slightly with the depth and basal respiration of aerobic layers.

MICROBIAL BIOMASS AND ITS ACTIVITY IN PEAT BOGS OF SIBERIA // Tomsk State Pedagogical University Bulletin. 2015. Issue 2 (155). P. 143-149

The authors studied soil microbial activity in oligotrophic, eutrophic and mesotrophic peat bogs of Siberia by method of substrate-induced respiration (SIR). Intensity of microbiological processes depends on the type of peat bogs and hydrothermal conditions. The average for vegetation period 2013, the highest microbial biomass was observed in oligotrophic peat bog of Vasyugan (4,16 mcg/g dry peat, with limits – 1,66–8,28 mcg/g d. p.). The minimum value of microbial biomass was recorded in mesotrophic peat bogs Kutushskoe (3,29 mcg/g d. p., with limits 0,78–6,94 mcg/g d. p.). Eutrophic bog Tagan on the microbial biomass took an intermediate position (middle – 3,74 mcg/g d. p., limits – 0,41–13,43 mcg/g d. p.). Investigated bogs can be arranged in the following order of intensive basal respiration: eutrophic bog Tagan > oligotrophic bog Vasyugan > mesotrophic bog Kutushskoe. It is fixed that in spite of genetic differences all bogs had the stable ecophysiological status. Functioning of microbial communities of peat bogs is within natural variability, and indicates their environmental sustainability. The eutrophic bog Tagan is not resistant to environmental factors.
