Abstract
The relationship between the activity of ATC oxygenase, CTC production and growth rate was investigated in a low-producing strain ofStreptomyces aureofaciens, closely related to the wildtype strain, and in a higher-producing variant. Different growth rates were achieved by using glucose, fructose and sucrose as carbon sources. Activity of the enzyme and CTC yield in both strains were inversely proportional to the rate of sugar utilization but in the higherproducing variant sugar utilization was slower than in the low-producing strain. The expression of ATC oxygenase was less sensitive to “catabolite repression” in the higherproduc ing strain. BT, a stimulator of CTC production, markedly inhibited growth of the higher-producing variant in a medium with slowly utilized sugars (fructose and sucrose) but had little effect on growth of the lowproducing strain. It also increased the level of ATC oxygenase in both strains under all experimental conditions. It could be established that there was no obligatory relationship between the increase of antibiotic synthesis and the increase of enzyme activity.
