[Effect of acetate on synthesis of exopolysaccharide ethapolan during Acinetobacter sp. B-7005 cultivation on the medium with ethanol].
A possibility of removal of C2-metabolism limiting and increasing of activity of acetyl-CoA-synthesis in Acinetobacter sp. B-7005--producer of exopolysaccharide (EPS) ethapolan with acetate introduction in the medium with ethanol. When adding potassium acetate 0.1% of into the medium without sodium cations containing 1% ethanol and 0.0009% calcium pantotenate at the stage of obtaining inoculate and at EPS biosynthesis, it is possible to realize the process of ethapolan production on nonbuffered medium in which total content of salts is reduced 4 times without decreasing the synthesis indices and rheological properties.
