A simple and feasible approach to purify konjac glucomannan from konjac flour--temperature effect.
A simple one-step purification process was provided to extract KGM from KF by phase separation. The results showed that appropriate temperature control was a key factor and the products were inodorous, colourless and of high purity at the optimal temperature 68 °C. In this purification, soluble sugar and starch of extracted KGM were nearly clearly reduced and up to 95%, 80% (T68) of protein and...
متن کاملMicrowave-assisted acid hydrolysis of konjac products for determining the konjac powder content.
The complete hydrolysis of konjac glucomannan (KGM) with an acid or enzyme generally takes a long time. To accelerate KGM hydrolysis without diminishing the conventional quality, a diluted acid hydrolysis of KGM with sulfuric acid was conducted using a microwave digestion system. The optimum conditions of microwave-assisted acid hydrolysis for KGM were: 10 mL of 0.25 M sulfuric acid, hydrolysis...
متن کاملModular Hyperthermostable Bacterial Endo-β-1,4-Mannanase: Molecular Shape, Flexibility and Temperature-Dependent Conformational Changes
Endo-β-1,4-mannanase from Thermotoga petrophila (TpMan) is a hyperthermostable enzyme that catalyzes the hydrolysis of β-1,4-mannoside linkages in various mannan-containing polysaccharides. A recent study reported that TpMan is composed of a GH5 catalytic domain joined by a linker to a carbohydrate-binding domain. However, at this moment, there is no three-dimensional structure determined for T...
متن کاملcDNA cloning and bacterial expression of an endo-β-1,4-mannanase, AkMan, from Aplysia kurodai.
Previously we isolated an endo-β-1,4-mannanase (EC 3.2.1.78), AkMan, from the digestive fluid of a common sea hare Aplysia kurodai and demonstrated that this enzyme had a broad pH optimum spanning 4.0 to 7.5 and an appreciably high heat stability in this pH range (Zahura et al., Comp. Biochem. Physiol., B157, 137-148 (2010)). In the present study, we cloned the cDNA encoding AkMan and construct...
متن کاملHybrid anaerobic baffled reactor for treatment of desizing wastewater
Polyvinyl alcohol-containing desizing wastewater discharged within final textile wastewater has a great impact to the environment due to its poor biodegradability. An improved lab-scale hybrid anaerobic baffled reactor was developed to treat desizing wastewater. The modification was achieved by increasing the height of hybrid anaerobic baffled reactor and application of proper effluent recycle ...
