Abstract
An object of the present invention is to provide a soft biomass decomposition method, a production method for a target substance from soft biomass, and an enzyme or group of enzymes for decomposing soft biomass. Provided is a soft biomass decomposition method, including a step of bringing an enzyme selected from specific exocellulase, endocellulase, and processive endocellulase into contact with soft biomass such as bagasse and rice straw. Also provided is a production method for a target substance from soft biomass by incorporating the soft biomass decomposition method as a step. Further provided is an enzyme or group of enzymes for decomposing soft biomass selected from specific exocellulase, endocellulase, and processive endocellulase.
Claims2
A method for producing ethanol from acid swollen cellulose, the method comprising:
- obtaining a decomposition product by contacting the acid swollen cellulose with an enzyme mixture of:
- an exocellulase comprising the amino acid sequence set forth in SEQ ID NO:
- 2, and
- a processive endocellulase comprising the amino acid sequence set forth in SEQ ID NO:
- 6,
- wherein a ratio of the exocellulase to the processive endocellulase in the enzyme mixture is from 25:75 to 50:50;
- and
- fermenting the decomposition product to obtain ethanol.
