| dc.description.abstract | The study of the screening of the media constitutions for the improvement of citric acid fermentation from paddy straw by Aspergillus niger was reported. Placket-Burman Design (P-BD) was employed and successful results were obtained. The screening of the 7 mineral salts (NH4NO3, KH2PO4, MgSO4, CuSO4, ZnSO4, FeSO4 and MnSO4) to gauge the most significant nutrients on [citric acid concentration, pH and reduce sugar] were concluded. It was found that NH4NO3 was the most significant nutrient. Moreover, KH2PO4 and MgSO4 affect were editing the citric acid production indirectly through the reduction of sugar and pH respectively. | en_US |
