Abstract
Official abstract text for this publication.
The present invention relates to a mannanase produced from Celluosimicrobium sp. strain HY-13 and more particularly to a highly active novel mannanase produced from Cellulosimicrobium sp. strain HY-13 as separated from an invertebrate. The mannanase produced from the said Cellulosimicrobium sp. strain HY-13 can be used in the decomposition of a mannan found in hemicellulose contained in grains and plants and in enhancing the utility value of a hydrolysate, which uses the decomposed mannan, for the transformation of biomass or as an animal feed material.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for producing a mannanase comprising the following steps: 1) culturing Celluosimicrobium sp. strain HY-13 deposited under the Accession Number of KCTC 11302BP in a medium containing mannan, and obtaining supernatant by centrifuging thereof; 2) inducing precipitation of water-soluble proteins by adding a precipitant to the supernatant of step 1); 3) obtaining a crude enzyme solution by dialyzing the precipitate of step 2) after eliminating insoluble precipitate from the same; and 4) purifying the mannanase from the crude enzyme solution of step 3). 2. An animal feed comprising grains, plants, and mannan and further comprising the mannanase having the amino acid sequence of SEQ ID NO:1 at a concentration of from 0.05 to about 5 weight part. 3. The animal feed of claim 2 which is a non-ruminant feed.
