Small angle neutron scattering studies have been carried out on cellulose fibers from ramie and Populus maximowicii (cotton wood). Labile hydrogen atoms were replaced by deuterium atoms, in water-accessible disordered regions of the fibers, to increase the neutron scattering contrast between the

A combined (enzymatic and chemical) process using a Bacillus pumilus strain (DKS1), isolated from the soil, was used to degum ramie bast fibres. After 24 h of incubation with the isolated pectinolytic strain using a low-cost medium, the weight loss of the ramie fibre was found to be 25% under small

Pectate lyases play an essential role in textiles, animal feed, and oil extraction industries. Pichia pastoris can be an ideal platform for pectate lyases production, and BspPel (a thermo-alkaline pectate lyase from Bacillus sp. RN1) was overexpressed by combined strategies, reaching

After 24 h of incubation with only purified pectate lyase isolated from Bacillus pumilus DKS1 (EF467045), the weight loss of the ramie fibre was found to be 25%. To know the catalytic residue of pectate lyase the pel gene encoding a pectate lyase from the strain Bacillus pumilus DKS1 was cloned in

The production of a highly alkaline and thermostable pectinase of Bacillus pumilus was optimized in submerged fermentation using Plackett-Burman design and response surface methodology. Three fermentation variables (C:N ratio, K(2)HPO(4), and pH), which were identified to significantly affect

OBJECTIVE To research the inherent properties of the co-expression of three types degumming-related enzymes and breed more powerful degumming strains. RESULTS Six tandem multimers of the pectate lyase gene, the xylanase gene, and the endo-1,4-β-mannanase gene, which are essential for degumming

Alkaline pectate lyases (Pels) have potential application in bioscouring of the textile industry. In this study, a thermo-alkaline Pel (BacPelA) gene from an alkaliphilic Bacillus clausii strain was cloned and overexpressed in Escherichia coli. The mature BacPelA exhibited maximum activity at pH

Pectate lyase (EC 4.2.2.2) catalyzes the cleavage of α-1,4-glycosidic bonds of pectin polymers, and it has potential uses in the textile industry. In this study, a novel pectate lyase belonging to polysaccharide lyase family 10 was screened from the secreted enzyme extract of Paenibacillus polymyxa

Banana, citrus and potato peels were subjected to treatment with hydroxyapatite nanoparticle (NP) supplemented purified pectate lyase (NP-PL), isolated from Bacillus megaterium AK2 to produce reducing sugar (RS). At both 50 and 90°C production of RS by NP-PL was almost twofold greater than that by
