Figure 5: Comparing biosurfactant activity and phenol removal percent recorded by isolate M2H2 1 (A & B) and isolate M2H2 14 (C & D) with and without induction regimen. Isolates were grown at 35 ± 2°C with agitation (180 rpm) for 6 days on MSM media supplied with coconut oil (2% w/v) together with phenol (500 mgl-1). Induction regimen was conducted using 500 mg l-1 of phenol to establish enough biomass prior to the addition of additional phenol (500 mgl-1) and coconut oil (2% w/v). *: indicates significant difference at P-value < 0.05 (paired t test).
