Production of xylo-oligosaccharides by immobilized-stabilized derivatives of endo-xylanase from Streptomyces halstedii
(2013-03-01)
An endoxylanase from Streptomyces halstedii was stabilized by multipoint covalent immobilization on glyoxyl-agarose supports. The immobilized enzyme derivatives preserved 65% of the catalytic activity corresponding to the ...

Study of the hydrolysis of TEOS-TMOS mixtures under ultrasound stimulation
(Elsevier B.V., 1996-10-01)
Pure and mixed tetramethoxysilane (TMOS) and tetraethoxysilane (TEOS) were hydrolyzed at 35 degrees C, using oxalic acid as a catalyst and ultrasound stimulation. The hydrolysis reaction was carried out in a specially ...

Production and physicochemical properties of resistant starch from hydrolysed wrinkled pea starch
(Wiley-Blackwell, 2011-11-01)
The content and physicochemical properties of resistant starches (RS) from wrinkled pea starch obtained by different molecular mass reduction processes were evaluated. Native and gelatinised starches were submitted to acid ...

Water hyacinth second-generation ethanol production: a mitigation alternative for an environmental problem
(2018-04-04)
Natural fibers are very abundant, especially those derived from water plant as water hyacinth. The water hyacinth, which is rich in cellulosic fiber content, has a great ability to adapt itself to harsh conditions and at ...
