Enzymic release of reducing sugars from oat hulls by cellulase, as influenced by Aspergillus ferulic acid esterase and trichoderma xylanase.

摘要: Hydroxycinnamic acids, mainly ferulic and p-coumaric are believed to be inhibitory ruminal biodegradability of complex cell wall materials such as oat hulls. Previous studies have shown that a novel enzyme, Aspergillus acid esterase, Trichoderma xylanase act synergistically break the ester linkage between attached sugar feruloyl polysaccharides, releasing from In this paper, we examined enzymic release reducing sugars hulls by actions individual enzymes (Aspergillus esterase at 13 mU, 6.4 U, 4678.4 U/assay; cellulase 20 levels, ranging 7.8 mU 2772.7 4096 U/assay) combined action six levels (62.5 2 16 128 1024 U/assay), mU/assay, two (1 U 256 U/assay). The amount total acid-extractable...
