文摘
- •
Spent coffee grounds were used to produce lignocellulolytic enzymes by Bacillus sp. R2.
- •
Untreated sent coffee grounds were the best inducers for cellulase and pectinase.
- •
Boiling water/EDTA treatment induced highest xylanase and peroxidase activities.
- •
Untreated spent coffee grounds presented the highest content of polyphenols.
- •
Cellulase and pectinase correlated strongly with polyphenols content.
