Lipase production by Aspergillus niger using sheanut cake: an optimization study

The effects of medium components affecting lipase production by Aspergillus niger AS-02 using sheanut cake (SNC) were studied based on the one-factor-at-a-time (OFAT) method and the face-centred central composite design (FCCCD). Of the six medium components analysed by OFAT, three (Tween-80, (NH4)2S...
