Abstract

We report scale-up production of alkaline lipases from Aspergillus niger MTCC 2594 using submerged stir tank fermenter (SSTF). The batch culture experiments and biomass studies suggest that olive oil used in the process reduced enzyme yield. We found that the addition of olive oil intermittently might be a potential fed-batch strategy to improve lipase production using Aspergillus niger MTCC 2594.
