The ability of sulfate-reducing bacteria Desulfovibrio desulfuricans Ya-11 i Desulfobacter sp. to use nitrate as electron acceptor
The ability of Desulfovibrio desulfuricans Ya-11 bacteria to use nitrate as terminal electron acceptor was studied. The level of biomass accumulation in the medium with nitrate changed depending on the initial NO3– concentration. At nitrate concentration 5 mM the bacterial biomass was the same as in...

| description | The ability of Desulfovibrio desulfuricans Ya-11 bacteria to use nitrate as terminal electron acceptor was studied. The level of biomass accumulation in the medium with nitrate changed depending on the initial NO3– concentration. At nitrate concentration 5 mM the bacterial biomass was the same as in the medium with sulfate. The intermediate product of nitrates reduction in D. desulfuricans Ya-11 is nitrite, and the final one – ammonium. High nitrates concentrations in the medium inhibit the process of dissimilatory sulfate reduction. Washed cells of D. desulfuricans Ya-11 fully reduced nitrite of the medium to ammonium. The ability of psychrophyllic sulfate-reducing bacteria Desulfobacter sp. to reduce nitrates at low temperatures is demonstrated. |
