研究方向为工业微生物分子生理学和系统生物技术,主要研究内容包括:
1、分子生理学和代谢工程。以乳酸菌及嗜酸、嗜碱、耐溶剂微生物为模型,利用基因组学和功能基因组学技术进行分子生理学研究,理解这些微生物过量合成大宗化学品的分子基础和调控机制,并在此基础上设计新的代谢工程策略,对微生物进行系统生物技术改造,实现大宗化学品的经济、绿色生产。
2、支撑系统生物技术的方法学。发展重要生物基化学品产生菌的高通量筛选方法,新型原核微生物遗传操作系统和基因组规模突变技术,不同水平(DNA、RNA、蛋白质、代谢物、代谢通量)组学数据的整合方法学,以及基因组规模代谢模型的构建及生物学功能预测方法。
主要论文包括:
