The surface layer, considered to be glycocalyx according to electron-microscopic observations, was separated from a low-production strain of Streptomyces aureofaciens by solubilization with urea and subsequent sonication. The isolation procedure was

Biosynthesis of chlortetracycline is localized differently under low- and high-production conditions (standard low-production strain and its high-production variant). The experimental evidence was based on the assay of anhydrotetracycline oxygenase i

Comparisons between submerged batch and chemostat fermentations of Gibberellafujikuroi show that major features of batch culture development relate directly to the degree of limiting substrate depletion and the corresponding growth rate. So-called se
