Values are the mean of nine replicates±standard error of mean. Values with same letters were not significantly different from each other in each column-based on duncan's post hoc test at p≤0.01. IHB B 1045= Bacillus altitudinis; IHB B 1702= B.cereus, IHB B 1059= Pseudomonas frederiksbergensis, IHB B 7048= P. mohnii, and IHB B 7168= P. moreii.
