摘要: 采用PCR技术和气相色谱-质谱联用方法对西北农林科技大学葡萄酒学院保藏的50株酒酒球菌的arcABC基因簇进行检测,以确定其产生氨基甲酸乙酯的特性。结果显示:所有菌株均含有arcA、arcB和arcC基因,即arcABC基因簇;在添加精氨酸的模拟酒培养基中培养酒酒球菌30d后,通过气相色谱-质谱联用方法能够检测出微量的氨基甲酸乙酯;说明这50株酒酒球菌都具有产生氨基甲酸乙酯的能力。

Abstract: PCR and GC-MS were used to detect arcABC gene cluster in fifty O. oeni strains conserved in the College of Enology of Northwest A&F University to determine their abilities for ethyl carbamate production. All the O. oeni strains were found to possess the genes arcA, arcB and arcC, i.e. arcABC gene cluster. A trace amount of ethyl carbamate was found after 30 d of cultivation in a simulated wine culture medium fortified with arginine, indicating that all these strains have the potential to produce ethyl carbamate.
