Synthesized compounds used as antimicrobial against the microorganisms in cooling fluids

Abstract EN

In this work synthesized compounds have been used as antimicrobial against the microorganisms which have been found in the cooling fluid of industrial purposes ' by using media culture the results showed that sodium and potassium salts of 2- Mercaptobenzothiazole (2-MBT) are comparatively highly active in killing bacteria. The pH of the cooling fluid samples had been measured after the addition of the media as well as the inhibitors 2-MBT, Sodium2-Mercaptobenzothiazole (Na2-MBT), Potassium2-Mercaptobenzothiazole (K2-MBT), and Benzothiazole disulfide (BTdisulfide). The results of PH measurement revealed that Na2-MBT and K2-MBT exhibit higher activity to inhibit the growth of bacteria compared with other synthesized compounds.

The turbidity for such media and inhibitors has also been measured and the results indicated that Na2 -MBT, K2-MBT have given low turbidity compared to that of other synthesized compounds.

The results indicate that the biological activities of the compounds Na2-MBT, K2-MBT are the best relative to the other synthesized compounds to inhibit the bacteria or the microorganisms that grow in the cooling fluid.
