Salt tolerance can influence the water and enzymatic activity of bacterial strains and confers high osmotolerance to withstand excessive external osmotic pressure (Adnan and Tan, 2007). Bacillus sp. is highly tolerant to salt concentrations ranging from 2% -10% (Ragul et al., 2017). At 2% concentration, growth was 7.98±0.56 Log (CFU•mL-1) and at 10% concentration, growth was found to be 6.98±0.29 Log (CFU•mL-1) (Figure 5). An important facet for a probiotic is its ability to survive the action of toxic metabolites like phenol and organic solvents like toluene.
