  • Mesophilic xylanases
    Patent number: 6140097
    Abstract: Mesophilic xylanases derived from Acremonium cellulolyticus. A mesophilic xylanase I, derived from the mold Acremonium cellulolyticus, capable of non-specifically hydrolyzing xylan mainly into xylose, xylobiose and xylotriose, having an optimal pH at 3.5 and an optimal temperature for action at 55.degree. C. as determined by saccharifying activity for soluble xylan as a substrate and a molecular weight of 30,000 as determined by SDS-polyacrylamide gel electrophoresis. A mesophilic xylanase II having an optimal pH a 3.8, an optimal temperature for action at 55.degree. C. and a molecular weight of 25,500. A mesophilic xylanase III having an optimal pH at 3.5, an optimal temperature for action at 50.degree. C. and a molecular weight of 33,500.
