Abstract

A system for the steady state cultivation of the anaerobic sulfate reducing bacteria Desulfovibrio desulfuricans is presented. Various experimentally determined growth parameters are also given. These include the values of total yield (15-16%), effective yield (37-43%), U (2.0 X IO-1 ’ hr'1), and K (1.6 x 10 H). The high Kg and low total yield are taken to indicate a difficulty in sulfate uptake by the cells. It was also found that the only sulfide produced was hydrogen sulfide.
