摘要
PROBLEM TO BE SOLVED: To provide (1) novel mannanase by which mannobiose can be obtained in high yield, the mannanase producing extremely little amount of monosaccharides (mannose and the like) even if hydrolyzing mannan, and to provide (2) a microorganism which produces such mannanase.;SOLUTION: The present invention provides mannanase MN-1 having the following physicochemical properties. 1) Action: acting on mannan to preferentially produce mannobiose. 2) Substrate specificity : hydrolyzing β-1,4 mannopyranoside binding. 3) Stable pH of 4-7. 4) Acting temperature of 30-50°C. 5) Temperature stability in 50°C or less. 6) Molecular weight of 40,000. Bacillus amyloliquefaciens MN47 (NITE P-01816) belongs to Bacillus and produces a mannanase.;SELECTED DRAWING: None;COPYRIGHT: (C)2017,JPO&INPIT
