| Abstract: | It has been one of the main bottlenecks for energy issue in the economic development nowadays.With the rapid progress of microbial synthetic biology,proteomics and metabonomics in the 21st century,it has been becoming a research hotspot to construct fermentative engineering bacteria utilizing less expensive,reproduc ible bio-material as carbon source to biosynthesize ethanol high efficiently,which has been engineered with the in troduction of marker gene-free deletion and DNA recombination technology.In this paper,the latest dynamics and achievement in the alcohol metabolism engineering of Escherichia coli,Saccharomyces cerevisiae and Zymomonas mo bilis were summarized briefly. |
