| 摘 要： | 双乙酰是乳制品中一种重要的风味物质。大多数乳酸茵（如乳球菌）都可以发酵葡萄糖和柠檬酸产生双乙酰。描述了在乳球菌中从柠檬酸代谢和糖酵解途径来生成双乙酰的代谢途径，以及利用基因工程和代谢工程技术来提高乳球菌的双乙酰生成量的策略。

| Abstract: | Diactyl is considered to be one of the most important compounds contributing to the final flovr and the aroma in a rang of fresh fermented dairy products. It is an end product of citrate/glucose metabolism by certain lactic acid bacteria such as lactococcus lactis. The metabolic pathway involed in citrate and glucose fermentation to diacetyl in lactococcus lactis is described in this paper. Genetic engineering and metabolic engineering strategies in lactococcus lactis for improving diacetyl formation also reviewed. |
