enzyme TtGlyDH preferentially catalyzes 1,3-dihydroxypropranone reduction rather than alcohol compound oxidation. Glycerol oxidization activity is faintly detected in the presence of a high concentration of glycerol (137 mM). No activity is detected with primary alcohols or diols. The highest glycerol oxidation activity is observed at the optimal growth temperature of 60°C in Tris-HCl buffer (50 mM, pH 8.0). Maximum DHA reduction activity is also observed at 60°C, and TtGlyDH exhibits the highest activity in an acetate buffer, compared with 91% maximum activity in an imidazole buffer at the same pH of 6.0

bioinspired immobilization of glycerol dehydrogenase by metal ion-chelated polyethyleneimines (PEI) as artificial polypeptides. Nanoparticles with diameters from 250–650 nm are prepared that exhibit a 1.4fold enhancement catalytic efficiency. The oligomeric GDH assemblies are coated and stabilized by the excessive manganese-chelated PEIs, which further prevents the disassociation of the GDH subunits, metal-mediated oligomeric assemblies of the enzyme. Half-life of immobilized GDH is enhanced by 5.6folds in aqueous phase at 85°C. Formation of multi-level interactions in the PEI-metal-GDH complex, mechanism, overview. A potential technique for multimeric enzyme immobilization with the advantages of low cost, easy operation, high activity reservation, and high stability. The activity of PEI-Mn2+-GDH gradually decreases over 5 cycles. PEI-Mn2+-GDH retains 71% and 53% of its initial activity after cycling through 3 and 5 successive reactions, respectively. The decrease in the activity of the recycled catalyst may be due to the leakage of GDH

Thermoanaerobacter mathranii can produce ethanol from lignocellulosic biomass at high temperatures. Deletion of the Ldh gene coding for lactate dehydrogenase eliminates an NADH oxidation pathway. To further facilitate NADH regeneration used for ethanol formation, heterologous gene GldA is expressed leading to increased ethanol yield in the presence of glycerol using xylose as a substrate. The metabolism of the cells is shifted toward the production of ethanol over acetate, hence restoring the redox balance. The recombinant acquired the capability to utilize glycerol as an extra carbon source in the presence of xylose resulting in a higher ethanol yield
