Abstract

The Lysini bacillus sp. strain GAKVM (MT476862) was mineralized at the maximum concentration 67.5μm within 72hrs in a mineral salt medium at 370C. The effect of initial phenol concentration on the biodegradation rate was studied using five different concentrations of phenol. Experiments performed for the time duration of 24hours-72hours while daily samples were withdrawn. Results of the specific growth rate in the initial concentrations presented increase in phenol concentration that amounts to decrease in the biodegradation and growth due to the inhibitory action of phenol. The bacteria showed efficient specific growth rate in 7.5μm and 22.5 μm and the specific growth activity of Lysini bacillus sp strain GAKVM at phenol concentration 7.5μm is calculated as 0.84 and those in 22.5μm phenol concentration is 0.495.
