Efficient conversion of glucose to acetaldehyde is achieved by nisin-controlled overexpression of Zymomonas mobilis pyruvate decarboxylase (pdc) and Lactococcus lactis NADH oxidase (nox) in L. lactis. In resting cells, almost 50% of the glucose consumed could be redirected towards acetaldehyde by combined overexpression of pdc and nox under anaerobic conditions.
通过在乳酸乳球菌中由乳链菌肽控制运动发酵单胞菌丙酮酸脱羧酶(pdc)和乳酸乳球菌NADH氧化酶(nox)的过表达,可实现葡萄糖向乙醛的高效转化。在静息细胞中,在厌氧条件下通过pdc和nox的联合过表达,几乎50%被消耗的葡萄糖可被重定向生成乙醛。
