It was determined that the neutralization o f the medium by the KOH solution in the process o f Acinetobacter calcoaceticus IMV B-7241 cultivation with the subsequent adding o f the fumarate (0.01 %, precursors o f the gluconeogenesis) and citrate (0.01 %, the regulator o f lipids synthesizes) at the end o f the exponential growth phase was accompanied by the increasing surfactant synthesis by 1.2-fold comparing to the same indexes without neutralization and by 3.5-fold comparing to the

The increasing o f the surfactant synthesis in the presence o f organic acids was caused by the 1.7-7-fold increased activity o f the biosynthesis enzymes o f glycolipids and aminolipids as well as the simultaneous functioning o f two anaplerotic ways.
