Abstract:

The creation and optimization of microbial cell factories are an important part of green biological manufacturing. Based on introduction of important enabling technologies for construction of high-efficiency microbial cell factories, recent progress for producing representative chemicals via microbial cell factories was reviewed. First, the important roles of some key enabling technologies, including both the classical methods such as promoter engineering and metabolic flow analysis and the new developments such as CRISPR gene editing, mutagenesis-coupled high throughput screening and artificial-intelligence-based bioinformatics, were described and discussed. Next, taking organic alcohols, organic acids, organic amines, polysaccharides and polyesters as examples, diverse genetic strategies for developing superior engineered cell factories were highlighted, and the highest production levels of different representative products were also summarized. Finally, the overall development trend and prospect for production of bulk chemicals and macromolecules by microbial cell factories in the future are forecasted.

Key words: microbial cell factory, enabling technology, metabolic engineering, bulk chemicals, macromolecules
