Revin V.V., Atyikyan N.A., Kostina E.G., Gogotov I.N. CALCIUM INFLUENCE UPON CHANGE OF CELL LIPIDS COMPOSITION OF RHODOCOCCUS ERYTHROPOLIS АС-858 Т IN THE COURSE OF BATCH AND SEMICONTINUOUS FERMENTATION IN ENVIRONMENTS WITH DIFFERENT HEXADECANE CONCENTRATIONThe authors investigate accumulation of total lipids and changes of phospholipid composition of cells of Rhodococcus erythropolis ВКМ Ас-858 Т depending on ion Ca2+ and hexadecane concentration in nutrient medium. It is shown that for growth and lipids accumulation of this bacterium in modified medium of Towson the optimum Ca2+ content is 4 mg/l, and hexadecane – 1%. In the course of fermentation the qualitative composition of phospholipids does not change, though their quantitative correlation alters. They used optimized medium for semicontinuous fermentation of bacteria by hemicontinuous method to get maximum biomass and lipids output, and that was done under 60% oxygenation of medium.
