  • Myceliuml growth and spore formation of Streptomyces albidoflavus SMF301 in submerged culture were compared with the metabolism of cysteine. Cysteine added to the culture was metabolized by cysteine desulfhydrase (EC 4.4.1.1.) to produce ammonium ions, hydrogen sulfide, and pyruvate. The redox potential of the culture broth was lowered immediately as the result of the metabolism of cysteine, which caused a lag period of mycelium growth. However enhanced activities of pyruvate dehydrogenase and a-ketoglutarate dehydrogenase were confirmed in the culture containing cysteine, indicating that pyruvate was utilized to support further mycelium growth.

  • Chemotaxonomic and numerical identification were carried out for a isolate of Streptomyces strain SMF301 producing spores in submerged culture. Fifty taxonomic unit characters were tested and the data were analyzed numerically using the TAXON program. The isolate SMF301 was identified to cluster 1A of Streptomyces and best matched to Streptomyces limosus which is a synonym of Streptomyces albidoflavus. Therefore, it was concluded that the isolate was identified to be a member of Streptomyces alidoflavus.
