Abstract
The present investigation was conducted to determine the chemical oxygen demand (COD) removal efficiency by Pseudomonas aeruginosa EMS1. The COD removal efficiency in the medium containing 1% metal working fluid (MWF) was 12% after cultivation of 4 days. The composition of optimum medium for the COD removal efficiency of 1% MWF by P. aeruginosa EMS1 were NH$_4$Cl 0.3%,$ K_2HPO_4\; 0.05%,\; KH_2PO_4\; 0.04%,\; MgSO_4.7H_2O\; 0.05%,\; CaCl_2.2H_2O 0.03%$ and $FeSO_4.7H_2O$ 0.04% at initial pH 7.0 and $30^{\circ}C$. Under this condition, the highest the COD removal efficiency was observed after 4 days.
