A PROCESS FOR PRODUCTION OF XYLAN-DEGRADING ENZYMES

摘要

This invention provides a process for production of the xylan-degrading enzyme endo-1,4-ß -D-xylanase, using a marine strain of the fungus Aspergillus niger. The endo-xylanase produced by this culture does not act on cellulose and is thus cellulose-free. Besides, the culture is able to grow and produce xylanase in the presence of 0.1 - 0.2% black liquor and marine water added to nutrient medium. The said fungus also produces other xylan - degrading enzymes such as p -xylosidase and a -L-arabinofuranosidase in the culture medium.
