Screening of Aspergillus for citric acid production from Palm Oil Mill Effluent

In this study, screening of potential microbes, especially Aspergillus, for citric acid production from Palm Oil Mill Effluent (POME) is carried out to improve the product yield. The fermentation of the raw material POME for the production of citric acid was conducted by the liquid state fermentatio...
