Two enzymes, L-arabinose isomerase and mannose-6-phosphate isomerase, from Geobacillus thermodenitrificans produced 118 g/liter L-ribose from 500 g/liter L-arabinose at pH 7.0, 70 degrees C, and 1 mM Co(2+) for 3 h, with a conversion yield of 23.6% and a volumetric productivity of 39.3 g liter(-1) h(-1).
两种酶,来自嗜热地芽孢杆菌的 L-阿拉伯糖异构酶和甘露糖-6-磷酸异构酶,在 pH 值为 7.0、70 摄氏度和 1mM Co(2+)的条件下,3 小时内将 500g/L 的 L-阿拉伯糖转化为 118g/L 的 L-核糖,转化率为 23.6%,体积产率为 39.3g 升(-1)小时(-1)。
