The redistribution of stable isotopes allows specifying the pathway of substrate utilization and identifying the relevant kinetic parameters. To describe degradation kinetics and identify predominant metabolic pathway for microbial substrate transfor

The production of CO2 during sediment decomposition in field and laboratory incubations is often reported to be higher than that of CH4. We present a mathematical description of cellulose conversion into methane and carbon dioxide in the anoxic sedim

We described mathematically the process of peat methanization in a boreal mesotrophic fen. Gaseous and dissolved CH4 and CO2 as well as their δ13C signatures were considered in the dynamic equation...

A dynamic model including isotope variables has proved to be an effective tool for evaluating the relative importance of the processes that are taking place in parallel and compete for the same substrate. We present a mathematical description of cell

The purpose of this study was to describe the dynamics of anaerobic oxidation of methane (AOM) coupled with sulfate reduction (SR) using experimental data from a continuous incubation experiments published earlier in order to show that formation of c

In the process of methane oxidation by nitrite ion, the latter, when in high concentration, inhibits the oxidation process. The effect of inhibition is incorporated in the proposed model, describing the dynamics of anaerobic oxidation of methane and

To identify predominant metabolic pathway for cellulose methanization new equations that take into account dynamics of 13C are added to the basic model of cellulose methanization. The correct stoichiometry of hydrolysis, acidogenesis, acetogenesis an

A kinetic analysis of nitrate denitrification by a single or two species of denitrifying bacteria with glucose or ethanol as a carbon source and nitrite or nitrous oxide as intermediate products was performed using experimental data published earlier

Soil thawing in permafrost zones can lead to the formation of readily digestible organic matter. This intensifies nitrate denitrification processes, leading to the formation of nitrous oxide, which produces a considerable greenhouse effect, and its r

Non-linear dynamics of nitrogen isotopic signature during uptake and assimilation of ammonium, nitrate and urea by culture of Thalassiosira pseudonana was described mathematically. Experimental data of the laboratory batch reactors were taken from Wa
