Bioremediation of Palm Oil Mill Effluent and Lipid Production by Lipomyces Starkeyi: A Combined Approach

The discharge of palm oil mill effluent (POME) on arable land causes large amounts of environmental distress due to its high concentration of phenolic compounds and chemical oxygen demand (COD). The approach of simultaneous microbial oil production and wastewater treatment is an attractive option to...
