Both ammonium and phosphate were regenerated when C∶N and N∶P atomic ratios of organic substrates were ≤10∶1 and ≤16∶1, respectively. Only ammonium was regenerated when C∶N and N∶P ratios were ≤10∶1 and ≥10-20∶1, respectively. On the other hand, neither ammonium nor phosphate was regenerated when C∶N and N∶P ratios were ≥15∶1 and ≥5∶1, respectively. In no case was phosphate alone regenerated. As bacteria were able to alter widely the C∶N∶P ratio of their biomass, the growth yield of bacteria appeared primarily dependent on the substrate carbon concentration, irrespective of a wide variation in the substrate C∶N∶P ratio.
