固定化己酸菌新材料研究报告

简要介绍了上世纪八十年代白酒行业微生物细胞固定化技术研究和应用情况。天津酿酒厂和天津啤酒厂合作,研究成功PVA和颗粒活性炭两种己酸菌固定化新材料。颗粒活性炭通过生产规模试验,产酸可达620mg/100m L以上,比传统方法提高两倍,比国内最先用于固定化细胞的琼脂包埋法提高29.4%,载体使用次数提高近两倍,达29次以上。细胞固定化技术,极大的简化了己酸菌培养工艺,降低发酵液成本,对提高津酒和同一类浓香型白酒质量,展示出很大潜力和美好前景,试验中还与南开大学合作,拍了电子显微镜照片,可清楚地看到菌体形态。

Research Report on New Material for Caproic Acid Bacteria Immobilization

The research and application of microbial cell immobilization technology in liquor industry during 1980s are briefly introduced.Two kinds of new materials,PVA and particle active carbon in the immobilization of caproic acid bacteria have been successfully developed by Tianjin distillery and Tianjin brewery cooperatively.Particle active carbon immobilization has passed the production scale test.The acid production was up to 620 mg/100mL,which was twice over that of traditional methods,and 29.4% higher than t...
