EFFECT OF THE VOLATILE FATTY-ACIDS ON PHOSPHATE-UPTAKE PARAMETERS BY PURE CULTURES OF ACINETOBACTER SP

Experiments were performed to examine the effect of volatile fatty aci ds (VFA) as carbon source, on the phosphate uptake parameters in four Acinetobacter strains. Acetic and butyric acids were equally good carb on sources for phosphate removal, while propionic acid was the least e fficient substrate. The best ratios of assimilated phosphate vs VFA co nsumed were 0.178 with acetic acid by Ac. calcoaceticus NRRL 4270, 0.2 1 with propionic acid by Ac. calcoaceticus NRRL 4270 and 0.187 with bu tyric acid by Acinetobacter sp.
