Background Ethanolic fermentation of lignocellulosic biomass is a sustainable option for the production of bioethanol. This process would greatly benefit from recombinant Saccharomyces cerevisiae strains also able to ferment, besides the hexose sugar ...

Research Progress on Physiological Activity and Biosynthesis of D-Tagatose(D-塔格糖的生理活性及生物合成研究进展) [PDF]
D-Tagatose is an important rare ketohexose. Its sweetness is 92% of sucrose, and its calories are only one third of sucrose. D-Tagatose was approved as a new raw material for safe food by the America's Food and Drug Administration and China's Health and ...

Screening and selection of wild strains for L-arabinose isomerase production [PDF]
The majority of L-arabinose isomerases have been isolated by recombinant techniques, but this methodology implies a reduced technological application. For this reason, 29 bacterial strains, some of them previously characterized as L-arabinose isomerase producers, were assayed as L-arabinose fermenting strains by employing conveniently designed culture ...

Immobilized Trienzymatic System with Enhanced Stabilization for the Biotransformation of Lactose
The use of ketohexose isomerases is a powerful tool in lactose whey processing, but these enzymes can be very sensitive and expensive. Development of immobilized/stabilized biocatalysts could be a further option to improve the process.

This review highlights recent advances in integrating biocatalysis and chemocatalysis in continuous flow to create streamlined, sustainable processes. It examines chemo‐enzymatic cascades combining at least one enzymatic and one chemical step, discusses challenges such as enzyme immobilization, leaching, and reactor clogging, and presents solutions ...

Subunit Structure of L-Arabinose Isomerase from Escherichia coli
Abstract l-Arabinose isomerase, isolated from l-arabinose-induced cultures of Escherichia coli B/r, has a molecular weight of 362,000 and an s020,w of 12.6 x 10-13 sec. Protonation of purified l-arabinose isomerase at pH 2.0 or treatment with 8 m urea results in the dissociation of the native enzyme into subunits which are homogeneous in the ...

Galactose to tagatose isomerization at moderate temperatures with high conversion and productivity
Production of tagatose, a sugar substitute, by isomerization of galactose suffers from unfavorable enzymatic kinetics, low enzyme stability, and low equilibrium constant.
