Abstract
Forty three different strains of Streptomyces spp. from some cultivated and sand areas of Egyptian soils were isola-bed , and most of these showed inhibitory activities against the Gram-negative bacterium Escherichia coli , the Gram-positive bacteria : Staphylococcus aureus , Bacillus subtilis, and Mycobacterium sp. and fungi : Aspergillus fumigatus , Fusarium sp. and Verticillium agaricinurn . Only the best seven for the production of plant growth regulators (PGR) ( I A A , GA 3 and kinetin) were used for further identification, using the more classical approach as follows : No. No . No. No . No. I No. No . 7 was identified as Streptomyces humiaus , 9 as Streptomyces corchorus’ii , 12 as Streptomgces mutabilis , 14 as Streptomyces diastaticus , 15 as Streptomyces atroolivaceus , 17 as Streptomyces lusitanus , and 30 as Streptomyces calvus ,
