In this research study the capacity of Bacillus subtilus and Bacillus cereus isolated from soil to inhibit the growth of pathogenic bacteria (Escherichia coli, Staphylococcus aureus , Klebsiella pneumonia , Pseudomonas aeruginosa ) isolated from urinary tract infection by producing antibiotic and study the effect of some environmental factors (temperature ,salt and pH) on growth of bacteria . the diameter of inhibition zone of B.subtilius was ( 25,30,22,19 ) while B.cereus was(18,15,20,11) against E. coli, S. aureus, K. pneumonia, P.aeruginosa respectively. The results showed ability of B. cereus to grow between 20-45 ̊ C while B. subtilus grow between 15-40 ̊ C and showed the optimum growth pH of B. subtilus was 7 while the optimum growth pH of B. cereus was 5. The results showed the B. subtilus was grown in 5% and 10% of NaCl concentrations while the B. cereus was grown in 5% NaCl concentration. So that we conclude the ability of bacilli bacteria to produce antibiotic inhibit growth of urinary tract infection bacteria . Key words : Antibiotic ,Inhibition zone , UTI.
