[Effect of carbon monoxide on the growth of sulfate-reducing bacteria and their oxidation of this substrate].

The effect of carbon monoxide on the growth of six strains of sulfatee-reducing bacteria have been studied as well as the ability of bacterial suspensions and extracts to oxidize CO. It was shown that sulfate-reducing bacteria possess a comparably high resistance to carbon monoxide. There are difference in the sensitivity of certain species and strains of sulphat-reducing bacteria to the content of CO in the gas phase. The cell suspensions and extracts are capable of oxidizing 100% CO in gaseous phase. The rate of carbon monoxide oxidation by extracts is much higher than by suspensions.
