Up to date, fungal species have been regarded as the most important microorganism for producing cellulase and hemicellulase
due to its ability such as extra cellular secretion and sufficient productivity (Maki et al.
5] colony forming units (cfu)/g of lactic acid bacterial per gram of fresh material; addition of enzyme E (a complex of cellulase and hemicellulase
, Snow Brand Seed Co.
, molasses, glucose, previously fermented juice and LAB were often used as silage fermentation stimulants to improve silage fermentation quality (Weinberg et al.

1993) who investigated the effect of two commercial cellulase/ hemicellulase
enzymes derived from Trichoderma reesei on the silage fermentation of ryegrass.
To break down these components cellulase, hemicellulase
and ligninase are required (Schiere and Ibrahim, 1989).
The different behavior of fiber fractions in the rumen observed during YM supplementation could be related to the reduction in the activity of hemicellulases
in the presence of tannins (Waghorn, 1996).
In filamentous fungi, production of the cellulose- and hemicelluloses-degrading enzyme, cellulases and hemicellulases
, are controlled at the transcriptional level by the available carbon source .
Among the topics are applying lignocellulosic residues in the production of cellulase and hemicellulases
from fungi, the regulation of plant cell wall degrading enzymes formation in filamentous fungi, ligninolytic enzymes from white-rot fungi and application in removing synthetic dyes, genetic tools for producing proteins in fungi, and lipases as imperative fat-degrading enzymes.
Because hydrolytic bacteria produce cellulases and hemicellulases
profusely, seed coats could be digested.

Additionally, Endofeed and Amylofeed contain side activities such as alpha-galactosidase, beta-mannanase, cellulases and hemicellulases
