生物发酵法制备葡萄糖酸镁

Preparation of Magnesium Gluconate by Biofermentation

采用生物发酵法从葡萄糖直接制备葡萄糖酸镁，实验表明：温度在３１℃，摇床转速２５０ｒ／ｍｉｎ，ｐＨ４～６时，其发酵转化率为８７３８％。

Magnesium gluconate is prepared by the way of biofermentation. The optimum reaction conditions are as follows:reaction temperature,fermentation reaction rotation speed of table, and pH of fermentation solution are 31℃,250r/min,and 4～6 respectively.On these conditions the fermentation yield is 87.38%.The product is identified and also up to the standard of food additive.
