Improving the productivity of malic acid by alleviating oxidative stress during Aspergillus niger fermentation by Na Wu, Mingyan Xing, Yaru Chen, Chi Zhang, Yingfeng Li, Ping Song, Qing Xu, Hao Liu, He Huang

“…Transcriptome and biochemical analyses demonstrated that both antioxidant enzyme-mediated oxidative stress defense system, such as superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPX), and nonenzymatic antioxidant system, such as glutathione, were enhanced in the presence of elastin peptide, suggesting elastin peptide relieving oxidative stresses is involved in many pathways. In order to further investigate the relationship between oxidative stress defense and malic acid productivity, we overexpressed three enzymes (Sod1, CAT, Tps1) related to oxidation resistance in A. niger, respectively, and these resulting strains display varying degree of improvement in malic acid productivity. …”
