Streptomyces is the largest genus of Actinobacteria and the type genus of the family Streptomycetaceae (Hong et al., 2009). [3] That puts ionophores in the antibiotic club, even though they work very differently compared to the antimicrobials that are used in human medicine. 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. Figure 1.

Type species: Streptomyces albus (Rossi Doria 1891) Waksman and Henrici 1943, 339 AL. Waksmanand Henrici's proposal of the genus Streptomyces in 1943 states: "Wehave selected as the type species of this newly-named genus, Streptomyces albus (Rossi-Doria emend Krainsky) comb.

Micrococcus Luteus. Sprial shapped. Over 500 species of Streptomyces bacteria have been described (Lee , Jung, & Hwang, 2005).Streptomyces species are chemoorganotrophic, filamentous streptomyces albus. Streptomyces albus, are also typical bacterial cell shapes. Conjugation between E. coli S17-1 containing pPM3891 and S. albus resulted in thiostrepton-resistant exconjugants, which were screened for viomycin sensitivity.
