摘  要:
试验旨在构建表达植物乳杆菌P-8亚油酸异构酶基因的酵母工程菌。以植物乳杆菌P-8的基因组DNA为模板,通过PCR扩增亚油酸异构酶基因后,与乳酸克鲁维酵母的表达载体p KLAC1相连;重组质粒电转化至乳酸克鲁维酵母菌CICC1777,经菌落PCR和序列分析进行阳性克隆的鉴定。结果表明,成功构建植物乳杆菌P-8亚油酸异构酶基因酵母表达载体和实现在乳酸克鲁维酵母菌的转化。这是首次将P-8亚油酸异构酶基因在乳酸克鲁维酵母中获得表达,为酵母体外表达蛋白研究以及构建高产CLA基因工程菌株和大规模应用在食品工业生产中奠定基础。

摘  要:
This experiment aims to construct a genetic engineering bacteria express linoleic acid isom-erase gene from Lactobacillus. P. P-8,laying foundation for further expression of linoleic acid isomer-ase gene. Linoleic acid isomerase gene was amplified by PCR from Lactobacillus.P.P-8, then the genewas cloned into Kluyveromyces lacti expression vector p KLAC1. The recombinant plasmid p KLAC1-LAI was transformed into K.lacti CICC1777. Genome of recombinant K.lacti was extracted and con-firmed by PCR method and sequence. The result shows that the successful construction of a genetic en-gineering bacteria expressing linoleic acid isomerase gene. It is the first time using K.lacti to express-ing linoleic acid isomerase gene from Lactobacillus.P.P-8, creating the necessary condition for the con-struction of yeast engineering bacteria.
