添加不同物质对法夫酵母生长及麦角甾醇合成的影响

Effects of Feeding Different Substrate on Phaffia Rhodozyma Growth and Ergosterol Production

将法夫酵母作为出发菌株,研究乙醇耐受性、盐胁迫、金属离子、磷酸盐和诱导剂等环境胁迫方式对法夫酵母生物量和细胞中麦角甾醇积累量的影响。结果表明,法夫酵母生物量相比对照组提高了20.6%,麦角甾醇积累量相比对照组提高了42.1%,因此,可以通过外源干预提高法夫酵母的环境耐受能力和麦角甾醇的积累量。

The effects of ethanol tolerance,salt stress,metal ions,phosphates,inductors respectively on the Phaffia rhodozyma growth and ergosterol accumulation were researched.The results have showed that the maximal biomass of Phaffia rhodozyma was increased by 20.6%,the maximal ergosterol content was increased by 42.1%,as a result,it is effective to raise the environmental tolerance of Phaffia rhodozyma and increase ergosterol content by external intervention.
