摘要

为了获得低产高级醇的工业酿酒酵母菌株,以酿酒酵母(Saccharomyces cerevisiae)菌株680bg为出发菌株,运用常压室温等离子体(atmospheric and room temperature plasma,ARTP)对其进行不同时长的诱变处理,结合孔板培养和分光光度法检测,建立了高通量筛选体系。最终,筛选获得了8株低产高级醇的酵母菌株,其中菌株ARTP-162的高级醇产量下降最为显著,降低了约21%,且遗传性能稳定。

Abstract

In order to obtain the industrial Saccharomyces cerevisiae strains with lower yield of higher alcohols, artificial evolution by atmospheric room temperature plasma (ARTP) was carried out. The high-throughput screening was also developed, which combined microplate culture system and spectrophotometry analysis. After two rounds of screening, eight mutants with lower yield of high alcohol were obtained. Among them, ARTP-162 showed the lowest higher alcohol concentration, which was decreased by around 21%. Furthermore, this mutant remained genetically stable after eight generations.

Key words： Saccharomyces cerevisiae; higher alcohols; high-throughput screening; genetic properties; ARTP
