Abstract:

With strong carbon fixation capacity and amenability to genetic manipulations, cyanobacteria are considered to be ideal cell factories for developing green biotechnology products. However, many research achievements are still in the laboratory stage, and the production efficiency of various chemicals is low for a long time. Combining the advantages of cyanobacteria and making full use of modern biotechnology will help promote the in-depth research and development of cyanobacterial cell factories. Taking the development process of cyanobacterial biotechnology as the main line, this paper introduced the achievements of genetic engineering, metabolic engineering and synthetic biology in the research of cyanobacterial cell factory, and pointed out that "drug and food homology" was the direction of foreign protein expression by cyanobacteria for application. To develop advanced synthetic biological tools so as to transform, design and reconstruct the metabolic pathways of cyanobacteria chassis cells was the only way to achieve efficient production of chemicals. This paper was expected to provide a reference for the in-depth study of cyanobacterial biotechnology.

Key words: cyanobacteria, genetic engineering, metabolic process, chemical, chassis cells, synthetic biology
