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.

β-MANNANASES OF FUNGI

Canadian Journal of Microbiology, 1965
β-1,4-Mannanases are of common occurrence in fungi. They are induced enzymes, the yields of enzyme being 10- to 100-fold greater when the organism is grown on mannan. All of the β-mannanases studied are endopolysaccharases acting on long chains in a random manner and unable to act on mannotriose or mannobiose.

β-Mannanase of Streptomyces

1988
Publisher Summary β-Mannanase refers to hydrolytic enzymes capable of hydrolyzing the (1→4)-β-D-mannopyranosyl linkages of the (1→4)-β-D-mannans, namely, mannan, galactomannan, glucomannan, and galactoglucomannan. The enzymes have been reported to be produced by various microorganisms including bacteria, fungi, and Streptomyces, and to occur in ...

[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.

Kinetics of β-mannanase fermentation by Bacillus licheniformis

Biotechnology Letters, 2003
Bacterial growth, konjac powder utilization and beta-mannanase production by Bacillus licheniformis NK-27 in batch fermentation were used to develop a model of the process. The optimal set of parameters was estimated by fitting the model to experimental data.

Purification and properties of mannanase from Bacillus subtilis

World Journal of Microbiology & Biotechnology, 1994
Extracellular mannanase from Bacillus subtilis NM-39, an isolate from Philippine soil, was purified about 240-fold with a yield of 7.3% by ammonium sulphate fractionation, DEAE-Toyopearl chromatography and Sephacryl S-200 gel filtration. Its M r was 38 kDa and it had a pI of 4.8 and optimum activity at pH 5.0 and 55°C.

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.
