Complete degradation of 500 mg/l
occurred in 168 h as shown in Figure 4. At 750 and 1000
mg/l of the lag phase was 36 and 48 h, respectively as
observed in Figures 5 and 6. It took nearly 204 and 252 h
for the complete degradation of phenol as shown in
Figures 7 and 8. Phenol had shown significant inhibitory
effect on growth of microorganism at higher concentrations
