Optimization of fermentation media for citric acid production using empty fruit bunches as substrate by central composite design

A solid state fermentation method will be carried out for the production of citric acid from empty fruit bunches (EFB) by employing the potential fungus Aspergillus niger (A106). Statistical optimization was carried out in terms of media composition and fermentation time by central composite design...
