Study included the selection of bacteria isolated from local is the most efficient among the seven isolates have been isolated from the soil of the city of Ramadi by collecting 20 sample soil from 6 different locations, based on possession of the effectiveness of inhibition a broad spectrum of bacteria toward the test was diagnosed with several tests and the appearance, biochemical It was diagnosed as isolating Bacillus subtilius and was labeled M1, Bacillus polymyxa was labeled as M3 owned inhibition highly effective against Staphylococcus aureus, pseudomonas aeruginosa and the Limits of 23 -30 mm and less against Escherichia coli, Klebsiella ssp isolated and characterized the M1 more effectively inhibition further examined the effect of temperature The growth of isolates that grow well in 40 degree heat, both 45 and isolating and isolation alone can M1 growth in the 50 degree Celsius heat either at low temperatures can not isolate both Selected from the growth in the degree of heat 5c.ْ and studying the impact of salinity on the growth of isolates Shows that it grows well in focus 3% NaCl The focus was able only 7% of M1 growth and sustainability of this focus, while the focus of 10% was not able to isolate both of growth in .
