| Abstract | ||
| Streptomyces are the biggest source for antibiotics production, they constitute about more than 75% in antibiotic productivity, and these antibiotics have a significant application in the commercial and therapeutic fields. The study included screening on the most potent antibacterial producing Streptomyces isolates. 41 Streptomyces isolates were primarily screened for antibacterial activity toward Gram positive bacteria (S. aureus) and Gram negative bacteria (E. coli), six isolates were selected (SMI-02, SMI-03, SMI-04, SMI-05, SMI-10 and SMI-16) which showed more antibacterial effect as related to other. Secondary screening revealed that two isolates (Streptomyces isolates SMI-04 and SMI-10) exhibited the potent and broadest antibacterial activity toward two G-positive (S. aureus and S. epidermidis) and three G-negative (E. coli, P. aeruginosa and K. pneumoniae). | ||
