Abstract
Palm Oil Mill Effluent (POME) is one of the highly polluting materials to the environment hence, utilization of this waste to produce useful industrial enzyme is a welcome development. The influence of different nitrogen supplementation using POME in lipase production by Aspergillus niger via fermentation was investigated. POME concentration with distilled water in the following ratios: 1:1, 1:2, 1:3, 1:4 and 1:5 were evaluated for the production of lipase via fermentation. The nitrogen supplements employed in POME media were potassium nitrate (KNO ), ammonium sulphate ((NH ) SO ), ammonium nitrate (NH NO ), urea and sodium nitrate 3 4 2 4 4 3
