Research ArticleOpen accessEvery word in the titleOptimization of the Fermentation Medium of Streptomyces ahygroscopicus ΔnysB, a Tetramycin Producing Strain, by the Response Surface MethodXiao Wang, Yao Dong, Xin Chen et al.Streptomyces ahygroscopicus ΔnysB is a genetically engineered strain that produces tetramycin by blocking the competition nystatin pathway. Response Surface Methodology (RSM) was used to optimize its fermentation medium composition. Taking the yield of tetramycin as the response value, the effects of corn starch, glucose, fish peptone, (NH4)2SO4, KH2PO4, and CH3COONa on the yield of tetramycin were investigated by the Plackett-Burman … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 1 · 9 Apr 2024 · 5,319 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Lead on the Chlorophyll and Antioxidant Response in the Leaves of Arabidopsis thalianaJun Xing, Cailing Yuan, Hui Yu et al.Lead (Pb) is a non-essential heavy metal element for plants. In this study, the effect of 0.025, 0.05, 0.1, 0.25, and 0.5 g/L Pb on the chlorophyll and antioxidant response was analyzed in the leaves of Arabidopsis thaliana. The results indicate that 0.025 g/L Pb had no significant effect on the fluorescence intensity of chlorophyll. However, 0.05, 0.1, 0.25, and … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 1 · 31 Mar 2024 · 4,628 accessesView PDFCite
