The influence of nitrogen supplementation on lipase production by Aspergillus niger using palm oil mill effluent
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
