[Characteristics of a continous culture of hydrogen bacteria under conditions of gas limitation].

The effect of the specific growth rate and limiting gas on the concentration of cells, the rate of gas utilization, and the economic coefficients was studied during continuous cultivation of Hydrogenomonas eutropha Z-1. Cell concentrations as functions of the specific growth rate with limitation by H2, 02, and CO2, were plotted as hyperbolae and were linear in the coordinates X, 1/D. The rates of gas absorption Q (M/1 - hr) grow linerly with the concentration of the cells in the culture. The economic coefficients are linear in the coordinates 1/y, 1/micron. The effect of the specific growth rate and kind of limiting gas on the ratios between absorbed H2, 02 and C02 is described.
