[Effect of phosphate and glucose on the growth kinetics and phsophohydrolase activity of Penicillium brevi-compactum]. 1978

V A Ezhov

The kinetics of growth of Penicillium brevi-compactum and the activity of exocellular phosphohydrolases were studied on media with different concentrations of glucose and phosphate. Exocellular phosphohydrolases were synthesized when the growth was decelerated due to the deficiency of phosphate rather than that of glucose. These enzymes were not synthesized if the growth was not limited by phosphate. Synthesis of exocellular phosphohydrolases was repressed by phosphate when the growth was limited by glucose. Apparently, a complex of exocellular phosphohydrolases is synthesized by the culture if its growth is limited by phosphate.
