摘要
对酿酒酵母(Saccharomycescerevisiae)工业菌株胁迫条件,包括高浓度酒精、高渗透压、高温、营养饥饿、氧化胁迫、糠醛毒性的耐受性进行了分析,同时测定了抗生素G418对这些菌株的最低抑菌浓度。结果表明,所测定的酵母菌株对这些逆境条件的耐受性有明显差别,表现出良好耐受性的是6508和安琪酵母菌株,同时多倍性的酿酒酵母工业菌株的耐受性均比单倍性实验室菌株高。
The stress resistance of Saccharomyces cerevisiae industrial strains to high-concentration ethanol, high osmotic pressure, high temperature, nutrient starvation, oxidative stress, furfural toxicity and the sensitivity to G418 were analyzed in this paper. The result showed that the stress resistances among these yeast strains were obviously different. The strains 6508 and Angel are the most resistant .The polyploidy industrial strains were more resistant to stress conditions than that of the haploid laboratory strains.
