Phenolics production from a novel substrate palm oil mill effluent by aspergillus niger ibs-103za: Evaluation of fermentation conditions and antioxidant activity

This paper introduces palm oil mill effluent (POME) as a novel substrate for production of phenolics under liquid state fermentation by Aspergillus niger IBS-103ZA with selected fermentation conditions. The statistical analysis showed a significant improvement at optimum fermentation conditions o...
