Abstract: In this study, the use of metallo-phenolic tolerant microbial consortia was proposed for its biosurfactant supported COD reduction, under high metallo-phenolic conditions, with high concentrations of phenol and heavy metals (Zn2+ and Cu2+) up to 850mg/L and 35mg/L, respectively. Results indicated that the toxicants had insignificant inhibition; albeit, comparative analysis indicated reduced emulsification efficiency of the biosurfactants under high toxicant loading, which will reduce the degreasing capabilities, thus reduced nitrification as the mass transfer will subsequently be reduced. The results showed potential for the consortia to be used in various types of wastewater including phenol and hydrocarbon contaminated water.
