| Abstract | ||
| The present study was include isolate mix of Sulfate Reducing Bacteria from cooling system of general state of fertilizers company southern region ( GSFC ) and study the effect of four biocides ( Naclo-7330 and STA-BR-Ex) which was used by fertilizer company and the biocide ( Spectrus-NX 1104 ) which was prepared by the company and the ( Chlorhexidine glconate ) which was prepare in laboratory on this bacteria. Also the present study include the effect of these biocides towards the planktonic and sessile Sulfate Reducing Bacteria. The result showed that the tow biocides ( Naclo-7330 and STA-BR-Ex) had no effect on the planktonic and sessile Sulfate Reducing Bacteria in the concentration ( 10-50 ) ppm and (100- 500 ) ppm , while the biocide (Chlorhexidine glconate ) showed clearly effect in concentration ( 20 ) ppm on the planktonic and ( 25 ) ppm on the sessile Sulfate Reducing Bacteria , while biocide ( Spectrus-NX 1104 ) showed highly effect than the other biocide at the concentration ( 15 ) ppm on the planktonic Sulfate Reducing Bacteria and (20 ) ppm on the sessile Sulfate Reducing Bacteria. | ||
