Reutilization of the Most Stable Coimmobilized Enzyme Using Glutaraldehyde Chemistry to Produce a New Combi-biocatalyst When the Coimmobilized Enzyme with a Lower Stability Is Inactivated

ACS Sustainable Chemistry & Engineering, Год журнала: 2024, Номер 12(17), С. 6564 - 6572

In the present article, glutaraldehyde was used to covalently coimmobilize lipase Eversa Transform 2.0 and β-galactosidase from Aspergillus oryzae. Both enzymes were adsorbed on amino supports modified with glutaraldehyde. However, first enzyme remained almost fully active under stress conditions, while lost a large percentage of its activity. To prevent necessity discarding both enzymes, immobilized following this immobilization strategy. The biocatalyst reduced eliminate chemical reactivity, then coimmobilized via ion exchange. incubation at high concentrations salt desorbed support. This combi-biocatalyst in three inactivation/rebuilding cycles where inactivated liberated by washing ionic strength replaced fresh enzyme, maintained activity throughout 3 cycles. That way, it possible use strategy reuse build new combi-biocatalysts after inactivation.

Computational Design of Burkholderia cepacia Lipase Mutants that Show Enhanced Stereoselectivity in the Production of l-Menthol

Journal of Agricultural and Food Chemistry, Год журнала: 2025, Номер unknown

Опубликована: Фев. 17, 2025

l-Menthol, valued for its aroma, cooling properties, and biological activity, is often produced as a mixture with d-menthol, which negatively impacts taste odor. To improve the purity of industrial l-menthol production, we engineered Burkholderia cepacia lipase (BCL) to stereoselectivity. While wild-type BCL achieves only 98% enantiomeric excess, used molecular dynamics simulations bound menthol acetate, combined computational rational design method (MSPER), identify key mutation sites. We experimentally confirmed that five mutations can effectively excess. In particular, Q88A increased excess 99.4% productivity from 14.5% 49.9%. Q88G exhibited highest at 54.0% 99.3% optical purity. These mutants offer greener, more efficient approach high-purity contributing sustainable chemical processes.
