Interest in the synthesis and application of thymol esters has increased recent years due to numerous applications associated with its biological activities. The enzymatic octanoate by esterification octanoic acid was explored using soluble lipases immobilized lipase biocatalysts solvent-free systems. Candida antarctica B form most active biocatalyst for this reaction. Different feeding strateg...

Translation of redox biocatalysis into a commercial hydrogenation flow reactor, with in-built electrolytic H 2 generation, was achieved using immobilized enzyme systems. Carbon-supported biocatalysts were first tested in batch mode, and then transferred continuous columns for -driven, NADH-dependent asymmetric ketone reductions. The thus handled comparably to heterogeneous metal catalysts, but ...

Modified electrodes using immobilized alcohol dehydrogenase enzymes for the efficient electroreduction of butyraldehyde to butanol are presented as an important step for the utilization of CO2-reduction products. Alcohol dehydrogenase was immobilized, embedded in an alginate-silicate hybrid gel, on a carbon felt (CF) electrode. The application of this enzyme to the reduction of an aldehyde to a...

The lignin mineralizing enzymes system of white rot fungi has tremendous catalytic prospect for oxidative bioremediation of a number of toxic pollutants and many other industrial uses. Immobilization enables the reuse of enzymes and making them industrially relevant and economical biocatalysts. Schizophyllum commune IBL-06 was cultivated for the secretion of lignin peroxidase (LiP) in pre-optim...

BACKGROUND Whole-cell biocatalysis in organic solvents has been widely applied to industrial bioprocesses. In two-phase water-solvent processes, substrate conversion yields and volumetric productivities can be limited by the toxicity of solvents to host cells and by the low mass transfer rates of the substrates from the solvent phase to the whole-cell biocatalysts in water. RESULTS To solve t...

Abstract Candida rugosa lipase (CRL) is an enzyme that widely used in biopharmaceutical and biopesticide industries due to its high catalytic ability reusability. However, conditions from industrial processes are often outside CRL stability range may cause denaturation or destabilization of the enzyme, causing it be not reusable, hence lowering economic value. To increase activity, stability, r...

The use of enzymes to catalyze chemical reactions has increased these recent years. Several models have been developed express the kinetics over biocatalysts. most well-known them, Michaelis-Menten, is used when only one substrate adsorbs on enzyme. In case esterification reaction, i.e., bimolecular system, a more complex kinetic model such as Ping-Pong Bi-Bi should be applied. advanced essenti...
