Purification and characterization of an endo-1,4-β-mannanase fromBacillus subtilisKU-1 [PDF]

FEMS Microbiology Letters, 1998
Endo-1,4-β-mannanase was purified to homogeneity from the culture supernatant of Bacillus subtilis KU-1 by ammonium sulfate precipitation, DEAE-Toyopearl, phenyl-Sepharose and FPLC Mono Q column chromatography by 810-fold with 39% yield. The molecular mass of the enzyme was estimated to be 39 kDa by SDS-PAGE and 40 kDa by gel filtration. It had a pI of

The Effect of Various Inclusion Levels of β-Mannanase on Nutrient Digestibility in Diets Consisting of Corn, Soybean Meal and Palm Kernel Expellers Fed to Growing Pigs [PDF]

American Journal of Animal and Veterinary Sciences, 2015
An experiment was conducted to determine the effects of various inclusion levels of I²-mannanase on the energy and mannan digestibility in diets containing corn, Soybean Meal (SBM) and Palm Kernel Expellers (PKE) fed to growing pigs. The PKE contained 92.6% dry matter, 4,417 kcal gross energy kg-1, 4.02% ash and 31.3% mannan on an as-fed basis.

Purification of a Thermostable β-mannanase from Paenibacillus thiaminolyticus - Characterization and its Potential Use as a Detergent Additive

, 2021
Endo-1, 4- β- D-mannanase (EC 3.2.1.78) is a glycoside hydrolase involved in random cleavage of β-1, 4- D-manno-pyranosyl linkages within mannans and heteromannans and generates branched and linear oligosaccharides.

Optimation of β-mannanase production on submerged culture of Eupenicillium javanicum as well as pH and temperature enzyme characterizations

Jurnal Ilmu Ternak dan Veteriner, 2012
Two successive experiments were conducted to determine the optimal substrate concentration of coconut meal (CM) and incubation time for production of β-mannanase from Eupenicillium javanicum. Both experiments were designed based on factorial. In the first experiment, the main factor was substrate concentration of 1, 2, and 3%, while the sub-factor was

Mannan endo-1,4-β-mannosidase from Kitasatospora sp. isolated in Indonesia and its potential for production of mannooligosaccharides from mannan polymers

AMB Express, 2017
Mannan endo-1,4-β-mannosidase (commonly known as β-mannanase) catalyzes a random cleavage of the β-d-1,4-mannopyranosyl linkage in mannan polymers. The enzyme has been utilized in biofuel production from lignocellulose biomass, as well as in production ...
