[Production of surfactants by Acinetobacter calcoaceticus K-4 grown on ethanol with organic acids].

The effect of fumarate (C4-dicarboxylic acid, a gluconeogenesis precursor) and citrate (a lipid synthesis regulator) on the production of surfactants by Acinetobacter calcoaceticus K-4 grown on ethanol has been studied. Simultaneous addition of fumarate and citrate to concentrations of 0.01-0.
