[Effect of cultivation conditions on cell composition of Pseudomonas methanolica]

The effect of cultivation conditions on the ocmposition of polymers was studied in the cells of Pseudomonas methanolica, BKM B-1131. The economic coefficient was high and the composition of polymers was normal if the growth was limited by methanol deficiency and the flow rate was low (D = 0.1 hr-1). The composition of the cells did not change but the economic coefficient decreased (0.12--0.21) if the growth was inhibited by pH.
