The synthesis of xylanases and cellulases is repressed if easily metabolizable carbon source like glucose, cellobiose
, xylose, or xylobiose is present .

all amino acids and a number of sugars, such as trehalose, cellobiose
, maltose, sucrose, glucose, and fructose, were tested.
The activity of [beta]-glucosidase or cellobiose
was determined according to Wood and Garcia-Campayo (1990), where 1 mL of cellobiose
solution of 0.
INTRODUCTION: Cellulases an enzyme that specificity cleaves the internal b-1, 4-glycosydic bonds of cellulose and release glucose, cellobiose
and cello-oligosaccharides depending on the characteristic of the enzyme.
Furthermore, phenotypic tests such as acid production from cellobiose
and citrate utilization, previously proposed to be useful for identification of E.
They use disaccharides including cellobiose
, maltose and lactose but not sugar alcohols.
Exoglucanase is active on crystalline cellulose hydrolysis and starts at the end of the chain, releasing cellobiose
from the reducing and non-reducing end of the chain.

Novel interaction between laccase and cellobiose
dehydrogenase during pigment synthesis in the white rot fungus Pycnoporus cinnabarinus.
During chemical pretreatment and treatment, five- and six-carbon sugars are produced in addition to cellobiose
and partially degraded cellulose.
It is catalase-positive, oxidase-negative, arabinose-negative, arginine-positive, it reduces nitrates to nitrites, blackens esculin iron agar and produces acid with darabitol, cellobiose
, maltose, D-mannitol, D-mannose, salicin and trehalose.
