Abstract
One hundered and fifty soil samples were collected from different city of Babylon/Iraq. Thirty three Actinomycetes isolates were obtained, purified and identified according to morphological properties and biochemical ltests. All isolates were tested for the irantimicrobial activities and screened for production of some important enzymes such as amylase, catalase, protease, cellulose and lipase. There salts obtained that 13 isolated have such potential and all 13 isolates have amylase activity. The most active
isolates in production of study enzymes were KO-AG18, HI-SA24 and KO-RS27. Most 13 Actinomycetes isolates were showed antimicrobial against some Gram-positive bacteria (Staphylococcus albus, Staphylococcus aureus and Streptococcus pyogenes) and Gram- negative (Klebsella pneumoniae, Escherichia coli, Serratia marcescens, Pseudomonas aeruginosa and Aeromonas hydrophila due to inhibition zone diameter (mm) ranged from 4-37 against gram negative and from 6-37 against gram positive bacteria.
