In 2014,Yin, Qun-jian; Chen, Xiao-xiao; Yang, Hong-sheng; Lin, Ming-shi; Mao, Xin-qi; Fang, Zai-guang published 《Fermentation conditions optimization for agarase-producing strain and the enzymatic properties》.Shipin Gongye (Shanghai, China) published the findings.Application of 6381-59-5 The information in the text is summarized as follows:
To improve enzyme activity, optimize the fermentation conditions and study its enzymic properties, the optimum fermentation conditions were determined by single factor experiments and orthogonal experiments: 0.3% yeast extract, 1.2% agar, pH 8, 28 °C, 0.02% K2HPO4 and 0.02% CaCl2. The optimized enzyme activity was up to 576.25 U/mL, which was 2.05 times compared with that before. Among yeast extract concentration, agar concentration and pH the three factors, pH played the most important role in the enzymic activity while yeast extract concentration the least. Studies on enzymic properties showed that its optimal temperature and pH were 36 °C and 7.5, resp. It was stable at pH 6.5-8 and 20-45 °C. The strain had the potential to produce agar oligosaccharide efficiently because of its high efficient degradation and good stability. After reading the article, we found that the author used Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrate(cas: 6381-59-5Application of 6381-59-5)
Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrate(cas: 6381-59-5) is a ferroelectric crystal with a high piezoelectric effect and electromechanical coupling coefficient. Application of 6381-59-5 It is utilized to break up emulsion in organic synthesis as well as a common precipitant in protein crystallography.
