| Abstract: | Cold-adapted cellulase can reserve high activity and higher catalytic efficiency even at low temperature.It can reduce the treatment process time and costs for heating or cooling in the application process with the advantage of high temperature cellulase can not compare.In this paper,the research progress on microbial cold-adapted cellulase was summarized,including the sources of microorganism,isolation and identification,enzymatic properties,structure and mechanism of cold-adapted,and genetic engineering. |
