Abstract: This study presents biodegradation of benzoic acid (BA) and anthranilic acid (AA) by <i>Micrococcus </i>sp. under aerobic conditions. Initial concentrations of BA and AA were varied (500-2500 mg/l) and almost complete biodegradation of BA and AA was observed within 30 h. Andrews kinetic model for single substrate was fitted to obtain maximum specific growth rates, half saturation and substrate inhibition constants. Cell growth with degrading BA (<img src='/image/spc_char/micro.gif'> <sub>m,BA</sub> = 0.645 h<sup>-1</sup>) was faster than with degrading AA (<img src='/image/spc_char/micro.gif'> <sub>m,AA</sub> = 0.63 h<sup>-1</sup>). Under biodegradation of BA and AA, first order rate constant values decreased with increase in initial concentration.
