Type species: Streptomyces albus (Rossi Doria 1891) Waksman and Henrici 1943, 339 AL. Conjugation between E. coli S17-1 containing pPM3891 and S. albus resulted in thiostrepton-resistant exconjugants, which were screened for viomycin sensitivity. Streptomyces albus, are also typical bacterial cell shapes. We disrupted the hrcA gene of S. albus by using a technique involving the conjugative transfer from E. coli to Streptomyces of a plasmid unable to replicate in Streptomyces. https://atlas.sund.ku.dk/microatlas/food/bacteria/Streptomyces_albus Not faecalis, Corynebacterium xerosis, Staphylococcus saprophyticus, Streptomyces albus, Serratia marcescens and Micrococcus luteus. streptomyces albus. approb.
