Consumption of organic substrates by anaerobic bacteria.Peer-reviewed article

Synthetic modelling medium has been used for periodic cultivation of mixed strains of anaerobic bacteria to study the production of volatile fatty acids at various temperatures, viz. 18, 35 and 40 °C, both with pH control and without it. The growth kinetics fits well the Jarovenko kinetic model (inhibition by product)    μ  = μ_m 1 /  (1 + P / K_p ) With increasing temperature the maximum specific growth rate is higher. At18 °Cit is μ_m = 0,0117 h^-1 and at 40 °C μ_m = 0,0217 h^-1. The K_p values increased from 0,2 g/l (18 °C) to 2,7 g/l (40°C). Apparently the increase is due to the changing relation in the proportions of produced acids.(In Slovak, English summary only)
