Abstract

The invention discloses a celluase producing bacterium. According to the invention, the classification name of the celluase producing bacterium is Penicillium piceum, the 18S rDNA (ribosomal deoxyribonucleic acid) gene sequence of a strain is shown in SEQ ID NO1, and the strain is preserved in China General Microbiological Culture Collection Center (CGMCC) with the preserving number of CGMCC5314 and the preserving date of October 9, 2011, Institute Microbiological Chinese Academy of Sciences, No.3 Beichen West Road 1 Chaoyang district, Beijing city. The celluase producing bacterium disclosed by the invention has good celluase and hemicellulase producing capabilities, and especially has good Beta-glucosidase production capacity. The celluase producing bacterium disclosed by the invention and the produced celluase and hemicellulase have wide application prospects in multiple industries such as biological fuel, medicine, daily chemical industry and food fermentation.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a cellulase-producing bacterium and its application. The cellulase-producing bacterium involved in the present invention has better enzyme-producing ability of cellulase and hemicellulase. Background technique [0002] Cellulose is the most abundant carbohydrate in nature, and it is a kind of renewable resource and energy. However, cellulose is difficult to be decomposed and utilized. How to convert cellulose into resources and energy that can be directly used is a difficult problem in front of people. There are two ways to degrade cellulose: chemical method and biological method. The chemical method has poor specificity, low purity, and pollutes the environment, while the biological enzyme method can overcome these shortcomings. attention. [0003] Cellulase is a general term for a group of enzymes that can degrade cellulose Beta-1,4-glucosidic bonds and turn cellulose into cellob...
