Abstract

The periplasmic nitrate reductase was assayed in intact cells of Thiosphaera pantotropha, after aerobic growth with either malate, succinate, acetate, butyrate or caproate present as sole carbon source. The level of enzyme activity was largely dependent upon carbon source and was lowest on malate and succinate, intermediate on acetate and highest on butyrate and caproate. The presence or absence of nitrate did not effect enzyme activity. The results indicate that, during aerobic growth, activity of the periplasmic nitrate reductase increases with the extent of reduction of the carbon substrate.
