Biodecolourisation of palm oil mill effluent (POME) by selected exogenous bacteria

Palm oil is now one of the top few edible oils in the world and will be leading player in the oil and fats market. However, palm oil mills generate large amount of by-product such as liquid effluent which requires effective management practices to minimize their negative impact on the environment. P...
