The biotransformation of NC by
Desulfovibrio sp. was studied.
The mass of NC was decreased by 4.9–9.3%. The rate of NC transformation was between 46 and 73
mg NC per mg of bacterial protein in 10 days. Moreover, N content (%N) in the remaining NC was reduced by 2–12%. The inhibitory effect of NC was clearly expressed when the growth of
D. desulfuricans 1388 in lactate/sulfate medium was initiated. The growth rate of bacteria was 1.5-fold greater when NC was not added (0.074 and 0.05
h
−1 respectively). The transformation of NC by
D. desulfuricans was accompanied by the appearance of nitrate in the culture liquid, the amount of which reached the peak by the 8th day.
