Embodiment Construction

[0010] The present invention is Penicillium lanosum 2# 10-2 No.110411-1 CGMCCNo.5703, which is used to decompose cellulose and lignin in straw.

[0011] The present invention separates and screens bacterial agents with high cellulase activity from a variety of soil samples. After 18S rDNA gene PCR sequencing, it is determined as Penicillium lanosum by gene sequence comparison, and the colonies are all circular , With hyphae, raised center, dull, opaque, 3-6mm in diameter, the colony is greenish and white after 3 days of cultivation. This fungus has higher enzymatic activity than commercial cellulase strains (CK) on the market. During the liquid culture of the bacterial agent, the strain showed the highest cellulase activity after 5 days, the carboxymethyl cellulase activity was 27.01μg / mL, the filter paper enzyme activity was 5.99μg / mL; in the semi-solid culture, the water content was The highest CX enzyme activity occurs at 70% (the total mass is the same as the liquid culture m...

Abstract

The invention relates to penicillium lanosum 2# 10-2 No. 110411-1 which is used for decomposing cellulose and lignin in straw. A colony is circular, has mycelia, is bulged at the center and is matt and opaque, and the diameter is 3-6mm.

Description

Technical field [0001] The invention belongs to the field of microorganisms. Background technique [0002] Cellulose is the main component of plant materials and the richest renewable resource on the planet. Under certain conditions, it can be hydrolyzed into monosaccharides. Mono sugar is then produced through microbial fermentation to produce a variety of useful products.At present, the application of cellulose enzymes in the food industry is becoming increasingly widely used. It has unique application prospects in food fermentation, food processing, and plant fiber raw materials degradation.There are also many domestic reports on this study. Yang Lifu and others have separated the degradation of higher bonus strains of banana stems and leaves.The liquid fermentation conditions were analyzed. Jin Zhongyue and others used microorganisms to degrade plant cellulose and compare and combine cellulose degradation strains to study the main factors that affect degradation efficiency. ...
