摘要
通过液体摇瓶分批发酵,研究无机盐对热带假丝酵母(Candida tropicalis)利用正十二烷发酵产十二碳二元酸的影响。结果表明,发酵培养基中各自添加5.0g/L磷酸氢二钠和1.0g/L磷酸二氢钾时,菌体产酸量最高分别可达45.72和34.29g/L,添加硫酸镁和氯化钠均不利于菌体产酸。
The effect of mineral salt on dodecanedioic acid(DC12)production from dodecane by Candida tropicalis was studied by batch fermentation in shake flask.The results showed that the highest DC12 yield could reach 45.72 and 34.29g/L respectively,when 5.0g/L disodium hydrogen phosphate and 1.0g/L potassium dihydrogen phosphate were added.It was not benefit for increasing DC12 production adding magnesium sulphate and sodium chloride to fermentation media.
