| Abstract: | Bacterial cellulose (BC) has been widely used in medicine, food and other fields because of its unique properties. Based on the domestic and foreign literature and team research results, this paper reviews the related research on BC synthesis and identification. Firstly, the screening of BC synthetic bacteria and the utilization of carbon source were analyzed, and the research ideas of reducing BC synthesis cost were summarized. Secondly, the methods to identify the synthetic products of strains were summarized, and the characteristics of different methods were summarized. Then combined with the team selected BC production bacteria XJL-06-4BC synthesis The results of enzyme gene analysis reviewed the BC synthesis pathway, the form of synthetase and the regulation of gene level, a new idea for BC to increase yield by changing the synthesis pathway at the molecular level. Finally, summarize the problems existing in BC microbial fermentation production, and put forward solutions from many angles. |
