低温脂肪酶基因在巴斯德毕赤酵母中的高效表达
HIGH-LEVEL EXPRESSION OF A COLD-ADAPTIVELIPASE GENE IN PICHIA PASTORIS
摘要
Abstract
A cold-adaptive lipase gene Zip-948 from Antarctic psychrophilic bacteria was ligated into the expression vector Ppic9k, which was subsequently transformed into yeast GS115. A high-level of yeast expression was observed. Lipase activity of the supernatant reached 27.5 U ? Ml-1 after 48 h fermentation, which is higher than that for most other low-temperature bacteria lipase genes expressed in Pichia pastoris.关键词
