Therefore, it should be removed effectively from the environment. In order to increase the degradative activity, the optimum conditions for <em>m</em>-chlorophenol degradation by <em>Pseudomonas putida </em>CP1, some physicochemical conditions like pH, temperature and carbon nitrogen ratio for the growth and degradation of most persistent monochlorophenol, <em>m</em>-chlorophenol by the organism was optimised. The pH optimum for <em>m</em>-chlorophenol degradation by the bacterium was between pH 6.5 and 7.0 and the temperature optimum was 30&deg;C for removal activity. Carbon : nitrogen (C:N) ratio of 3:1 was found best for effective removal of chemical oxygen demand (COD) and <em>m</em>-chlorophenol by the bacterium.</p> <p><strong>Keywords:</strong> <em>m</em>-Chlorophenol degradation, <em>Pseudomonas putida </em>CP1, Chemical oxygen demand (COD)</p><p>DOI: <a href="http://dx.doi.org/10.3329/bjm.v23i2.884">http://dx.doi.org/10.3329/bjm.v23i2.884</a>&nbsp;</p> <p>Bangladesh J Microbiol, Volume 23, Number 2, December 2006, pp 159-161</p> ER -
