BETA-1,3-XYLANASE, MICROORGANISM PRODUCING THE SAME, PRODUCTION PROCESS FOR XYLANASE, AND THE USE THEREOF |
摘要 |
PROBLEM TO BE SOLVED: To obtain a novel β-1,3-xylanase that has a strong β-1,3-xylan- hydrolyzing activity. SOLUTION: This is an enzyme that catalyzes the hydrolysis of β-xylan to low oligomeric saccharides mainly including xylobiose (disaccharide), xylotriose (trisaccharide), xyloteteraose (teterasaccharide), xylopentaose (pentasaccharide) and xylohexaose (hexasaccharide) and has the following physical and chemical properties: (a) molecular weight: 57,000; (b) isoelectric point: 3.6; (c) solubility: soluble in water; (d) the optimal temperature: 40 deg.C; (e) the optimal pH: 7.5 (f) the pH stability: pH 6.0-9.0; (g) thermal stability: stable up to 30 deg.C. |
