【摘要】 将橡子仁粉碎后，经酸水解、中和及滤洗制成发酵用糖液，接入黑曲霉新菌株ＨＡ６０８，并加入２．０％～４．０％的产酸促进剂Ｂ，发酵生产柠檬酸．糖液浓度为１０％～１２％时，发酵周期１２０～１３０ｈ，转化率１１０％以上更多还原

【Abstract】 Acorn kernels are grinded into powders,hydralysed by acid,neutralized,filtered, washed,and finally a kind of hydrolysed syrup is madeforfermentation.Thehydrolysed syrup inoculates with new strain Asp.niger HA608.2.0%￣4.0% of promotive agent B is added into syrup to produce citric acid.When the sugar condensation of the syrup reduced to 10%￣12%,the fermentation time cycle is 120￣130 hours and the invert ratio of the total sugar into acid is above 110%.更多还原
