A bi-enzymatic system for efficient enantioselective bioconversion of racemic mandelic acid

Journal of Molecular Catalysis B: Enzymatic, 2013
Abstract ( S )-Mandelate dehydrogenase (SMDH) from Pseudomonas aeruginosa is a FMN-dependent enzyme and catalyze the oxidation of ( S )-mandelic acid to benzoylformic acid (BA), resulting in the reduction of FMN. Laccase catalyze the conversion of ferrocyanide to ferricyanide meanwhile oxygen is reduced to water.

Integrated CO2 capture and enzymatic bioconversion in supported ionic liquid membranes

Separation and Purification Technology, 2012
Abstract This work proposes an innovative concept for the removal of CO2 from flue gas streams using supported liquid membranes with non-volatile ionic liquids (or solvents), comprising a thermoresistant enzyme that enhances the selective transport of CO2. Membrane stability, CO2 and N2 permeability and CO2/N2 ideal selectivity was determined in the

Bioconversion of wheat straw to ethanol: Chemical modification, enzymatic hydrolysis, and fermentation

Biotechnology and Bioengineering, 1981
AbstractNative wheat straw (WS) was pretreated with various concentrations of H2SO4 and NaOH followed by secondary treatments with ethylene diamine (EDA) and NH4OH prior to enzymatic saccharification. Conversion of the cellulosic component to sugar varied with the chemical modification steps.

One‐Pot Bioconversion of l‐Arabinose to l‐Ribulose in an Enzymatic Cascade

Angewandte Chemie, 2019
AbstractThis work reports the one‐pot enzymatic cascade that completely converts l‐arabinose to l‐ribulose using four reactions catalyzed by pyranose 2‐oxidase (P2O), xylose reductase, formate dehydrogenase, and catalase. As wild‐type P2O is specific for the oxidation of six‐carbon sugars, a pool of P2O variants was generated based on rational design ...

Bioconversion of Welan Gum from Kitchen Waste by a Two-Step Enzymatic Hydrolysis Pretreatment

Applied Biochemistry and Biotechnology, 2017
Kitchen waste (KW) is a worldwide issue, which can lead to environment pollution. Nevertheless, it is also a low-cost and sustainable resource for bio-production. Meanwhile, welan gum (WG) is one kind of the most important exopolysaccharide but with high material cost.

High-yield enzymatic bioconversion of hydroquinone to α-arbutin, a powerful skin lightening agent, by amylosucrase

Applied Microbiology and Biotechnology, 2012
α-Arbutin (α-Ab) is a powerful skin whitening agent that blocks epidermal melanin biosynthesis by inhibiting the enzymatic oxidation of tyrosine and L-3,4-dihydroxyphenylalanine (L-DOPA). α-Ab was effectively synthesized from hydroquinone (HQ) by enzymatic biotransformation using amylosucrase (ASase). The ASase gene from Deinococcus geothermalis (DGAS)
