EXPRESSION
ORGANISM
UNIPROT
LITERATURE
a medium based on starch casein minerals containing carboxymethyl cellulose and beef extract supports enhanced cellulase production
endo-beta-1,4-glucanase activities after growth on wheat straw, wheat bran and corn straw are 2.51, 1.62 and 5.10 U/ml
Thermochaetoides thermophila
-
enzyme production is maximal on wheat bran fed with 20% inoculum, at initial pH 5, 45°C and moisture ratio 1:3. The supplementation of wheat bran with yeast extract, Tween-80 and glycine further improves enzyme titres
expression is induced by microcrystalline cellulose, bran, carboxymethyl cellulose, rice straw, and corn stalk
expression is induced in presence of carboxymethyl cellulose
expression is markedly induced by growth on amorphous polysaccharides such as alkali-treated bagasse and xylan
expression is repressed by glucose
expression upon supplementation of medium with 1% (w/v) wheat bran
-
extracellular cellulase is expressed from the early-exponential phase (4 h) and reaches a maximum level during the stationary phase of bacterial growth (20 h)
extracellular endo-beta-1,4-glucanase isozyme Endo1 is induced by carboxymethyl cellulose
extracellular endo-beta-1,4-glucanase isozyme Endo2 is induced by carboxymethyl cellulose
growth on methyl cellulose supports the highest yield of beta-glucosidase (177.5 U/mg) at pH 6.0 and 30°C at 96 h of fermentation with liberation of 2.121 micromol/ml glucose
-
highest expression at 50°C when cultivated on wheat bran
highest expression occurs after 4 days of induction using 25 M/l methanol at 30°C when the yeast cells are cultured in a YPL medium
in regulator cre1-silenced strain C88, the filter paper hydrolyzing activity and beta-1,4-endoglucanase activity are 3.76-, and 1.31fold higher, respectively, than those in the parental strain when the strains are cultured in inducing medium for 6 days. The activities of beta-1,4-exoglucanase and cellobiase are 2.64-, and 5.59fold higher, respectively, than those in the parental strain when the strains are cultured for 5 days
L-sorbose induces the enzyme in strain PC-3-7
-
maximum cellulase production upon growth on sugarcane baggase used as agro-waste carbon source
maximum endoglucanase production is observed after 72 h at 55°C, pH 5.5, and 70% moisture level. Addition of 0.3% of fructose, peptone, and Tween-80 further enhances the production of endoglucanase
-
optimized conditions for production of filter paper exocellulase and endocellulase in conical flasks are moisture content 68.6 weight% and soybean bran concentration 0.9 weight%
production of cellulolytic enzymes is supported maximally on wheat bran fed with 20 % inoculum, at initial pH 5, temperature 45°C and moisture ratio 1:3. The supplementation of wheat bran with yeast extract, Tween-80 and glycine further improves enzyme titres
production of xylanase and cellulases under solid state fermentation using a carbon source a mixture (5.0 g) (1:1 w/w) of wheat bran and sugar cane bagasse
strain can grow and produce cellulases in the range of 35 to 55°C although 40 to 50°C seems to favor growth and cellulase production
-
the number of workers in the colony influences the cellulase gene expression in alates and primary reproductives, queens and kings, in asscoiation with development of of vitellogenic ovarioles and testis, overview
yeast extract stimulates enzyme production
