[Mannanases of microorganisms].

Ukrains'kyi biokhimichnyi zhurnal (1999 ), 2010
The current data on microbial mannanases are summarised in the work. The questions concerning the spreading of mannanases substrates--mannans in nature, their structural variations are regarded. The production of mannanases by micro-organisms of different taxonomic groups, their physico-chemical properties and substrate specificity are described.

Isolation of β-mannanase-producing microorganism

Journal of Fermentation and Bioengineering, 1994
Abstract A bacterium which produced β-mannanase was isolated from soil using copra meal as a crude mannan preparation. The partially purified enzyme solubilized copra mannan and produced mannobiose, mannotriose, and mannotetraose as major products. The enzyme appeared to hydrolyze the unsubstituted β-mannan domain preferentially.

α-Mannanase from Rhodococcus erythropolis

1988
Publisher Summary This chapter describes the production, purification, and characteristics of Rhodococcus erythropolis possessing properties of α-mannanase. a-Mannanase is assayed by measuring the liberation of mannose from bakers' yeast mannan. The mannose released is determined by reducing sugar according to the method of Somogyi.

Microbial Mannanases: An Overview of Production and Applications

Critical Reviews in Biotechnology, 2007
Microbial mannanases have become biotechnologically important since they target the hydrolysis of complex polysaccharides of plant tissues into simple molecules like manno-oligosaccharides and mannoses. The role of mannanases in the paper and pulp industry is well established and recently they have found application in the food and feed technology ...

Microbial Mannanases: Properties and Applications

2013
Mannans are a major constituent of the hemicellulose fraction of lignocelluloses. Mannans perform distinct functions as structural components in cell walls of softwoods and storage functions in seeds. Enzymatic hydrolysis of mannan involves the backbone hydrolyzing endo-β-mannanases and β-mannosidases.

β-d-mannanases in germinating lucerne (alfalfa) seeds

Carbohydrate Research, 1980
Extraction and fractionation of the beta-D-mannanases in germinating lucerne produced four fractions if extracts were stored prior to chromatography. However, when extracts were applied rapidly to DEAE-cellulose, one of the fractions of high molecular weight (separated subsequently by gel chromatography) was not detected, indicating that it was formed ...

β-d-Mannanase

1988
Publisher Summary β-D-Mannanase enzymes are endohydrolases that cleave randomly within the 1,4-β-D-mannan main chain of galactomannan, glucomannan, galactoglucomannan, and mannan. The β-mannanases from a range of legume seeds, Bacillus subtilis and Irpex lacteus culture filtrates, and the gut solution of Helix pomatia have action patterns on ...

Mannanase production by the lettuce endosperm

Planta, 1979
Endo-β-mannanase (EC 3.2.1.78) is produced and secreted by the cells of the endosperm of lettuce (lactuca sativa L.) "seeds" (achenes). In imbibed intact seeds, production is prevented by inhibitors. If the endosperm is incubated alone, these inhibitors can be removed by leaching, allowing mannanase production.

[Purification and characterization of mannanase from an alkaliphilic mannanase producing bacterium HMTS15].

Wei sheng wu xue bao = Acta microbiologica Sinica, 2012
To isolate and identify an alkaliphilic mannanase producing bacterium, purify and characterize mannanase thereof.Mannanase-producing alkaliphilic bacterium HMTS15 was isolated by alkaline agar with konjak from water sample of Hamatai Lake in Inner Mongolia, China.

Endo-β-mannanase in tomato fruit

Phytochemistry, 1989
Abstract Extracts of ripe tomato fruit hydrolysed locust bean galactomannan, a linear β-1,4-mannan with branches of single galactose residues. The viscosity of the reaction mixture decreased sharply relative to the release of reducing groups, indicating random hydrolysis of the mannan backbone of the polysaccharide.
