CO_2控制对玉米发酵生成柠檬酸的影响分析

CO_2 Control Impact Analysis of Citric Acid Fermented Corn

在黑曲霉利用玉米发酵生成柠檬酸过程中,影响发酵的因素有很多,如溶解氧、培养温度、罐压、pH值等,但CO2对黑曲霉柠檬酸的影响也很大,一定量的CO2体积分数对提高柠檬酸的收率有一定作用。

In Aspergillus niger fermented corn citrate process,many factors affect the fermentation,such as dissolved oxygen,temperature,pressure,p H,etc. The effective of CO2 for Aspergillus niger citric acid is also great,CO2 concentration in a certain amount of increase the yield of citric acid has a role.
