In this paper, glucosamine was produced by acid hydrolysis of five mushrooms. The glucosamine yields were investigated, and the optimum conditions were obtained as follows: acid type, sulfuric acid; acid concentration, 6 M; ratio of raw material to acid volume, 1 : 10; hydrolysis temperature, 100°C; and time, 6 h. Under these conditions, the glucosamine conversion from chitin content reached up to 92%. The results of hydrolysis kinetics indicated that hydrolysis of five mushrooms to glucosamine followed zero-order kinetics. Moreover, the relatively low activation energy for hydrolysis of straw mushroom (18.31 kJ/mol) and the highest glucosamine yield (56.8132 ± 3.5748 mg/g DM, 0.9824 g/g chitin) indicated that hydrolysis of straw mushroom was energy-saving. Thus, sulfuric acid hydrolysis of straw mushroom for glucosamine production should be considered as an efficient process for the future industrial application. However, further study is needed for glucosamine purification.

五个蘑菇中几丁质酸水解产生氨基葡萄糖的动力学模型

在本文中，葡萄糖胺是通过五个蘑菇的酸水解产生的。研究了葡糖胺的产率，并获得了最佳条件，如下所示：酸型，硫酸，酸浓度6 M；原料与酸的体积比为1:10; 水解温度100℃；时间6小时 在这些条件下，几丁质含量的氨基葡萄糖转化率高达92％。水解动力学结果表明，五个蘑菇水解为葡萄糖胺遵循零级动力学。此外，秸秆蘑菇的水解活化能较低（18.31 kJ / mol），葡萄糖胺产量最高（56.8132±3.5748 mg / g DM，甲壳素0.9824 g / g），表明秸秆蘑菇的水解是节能的。从而，草菇的硫酸水解用于生产氨基葡萄糖应被认为是未来工业应用的有效方法。但是，需要进一步的研究来纯化氨基葡萄糖。
