is a powerful physical microbial mutagenesis tool used for microorganism breeding. The ARTP mutation system has been successfully applied for mutating S. platensis, which enables the generation of mutant 3-A10... the mortality rate of microorganism mutagenesis reached 80%-90%, the positive mutation rate was the highest and the mutation effect was considered optimum [21]. The growth curves of B. ......
) by using agar well diffusion method. The bacterial strains were collected from Khyber Teaching Hospital KPK, Pakistan. Fresh culture of each test microorganism at the concentration of 7.5×106 ... in suppressing the growth of the tested microorganism to variable potency, which can be examined clearly from the size of produced inhibition zones. It was, in fact, due to (1) the type of test bacteria......
