Self-cloning in Streptomyces griseus of an str gene cluster for streptomycin biosynthesis and streptomycin resistance.
An str gene cluster containing at least four genes (strR, strA, strB, and strC) involved in streptomycin biosynthesis or streptomycin resistance or both was self-cloned in Streptomyces griseus by using plasmid pOA154. The strA gene was verified to encode streptomycin 6-phosphotransferase, a streptomycin resistance factor in S. griseus, by examining the gene product expressed in Escherichia coli...
متن کاملDecision phase regulation of streptomycin production in Streptomyces griseus
lnstitut fur Chemische M i k ro biolog ie, Berg isc h e Universitat GH Wuppertal, Gauss-Str. 20, 421 09 Wuppertal, Germany The streptomycin (Sm) producer, Streptomyces griseus N2-3-11, shows medium-independent biphasic kinetics of the vegetative or exponential growth phase (EGP), reflecting an innate clock-like behaviour of growth and differentiation. The 5. griseus growth and development cycle...
متن کاملProduction of streptomycin from chitin using Streptomyces griseus in bioreactors
Streptomyces griseus was cultured in three different bioreactors in a medium containing chitin flakes. When a conventional bioreactor stirred by two sets of Rushton impellers and operated at high speed was used, the yield of streptomycin (3.1 mg/l) was the highest observed and occurred at approximately 500 hours. Cultivation of S. griseus in a bioreactor stirred at low speed by a U-shaped paddl...
متن کاملStreptomycin resistance in a streptomycin-producing microorganism.
Cell-free extracts of Streptomyces bikiniensis contain an adenosine 5'-triphosphate-dependent kinase which inactivates streptomycin (Sm) and dihydrostreptomycin by phosphorylation. The products have been identified as streptomycin 6-phosphate and dihydrostreptomycin 6-phosphate. Activity was not present in logarithmic-phase cells, which were susceptible to 25 mug of Sm per ml. In stationary-pha...
