A survey was undertaken for bacterial isolates capable of producing antimicrobial agents from different Egyptian soils .These isolates were tested against various species of microorganisms (G+, G-, spore formers , yeast and fungi) using inhibition zone determination technique and standard disks of antibiotics as reference. One or more of the pathogenic bacterial strains used as tested organisms were affected by antimicrobial substances produced by bacterial isolates as indicated by inhibition zones formation .The effect of antimicrobial substances produced by bacterial isolates were compared with the effect of 11 antibiotic disks as reference. The most effective isolates against the tested organisms were identified by API 50 CHB system which indicate that these isolates were Bacillus licheniformis, Bacillus amyloliquefaciens, and Bacillus subtilis. Whole sediment produced by the five bacterial strains were found to be safe when using as ration for albino rats.
