摘要
细菌纤维素(BC)因其独特性能被广泛应用于医药、食品等领域,目前其高产量菌株筛选、合成成本降低及合成途径改良等成为研究热点。本文依据国内外文献并结合团队研究成果对BC合成与鉴定的相关研究进行综述。首先对BC合成菌筛选及碳源利用的研究进行了分析,总结了降低BC合成成本的研究思路。其次对鉴定菌株合成产物的方法进行了归纳,总结了不同方法的特点。然后结合本团队筛选出的BC生产菌XJL-06-4 BC合成酶基因分析结果,综述了BC合成途径、合成酶存在形式以及基因水平调控作用,为BC在分子水平上通过改变合成途径提高产量提供新思路。最后,总结BC微生物发酵生产存在的问题,多角度提出解决方案。
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.
