要旨

An efficient nanobioconjugate of lipase B from Candida antarctica was prepared by covalent binding onto carboxy-functionalized single-walled carbon nanotubes and tested in batch and flow modes for the enzymatic kinetic resolution of several racemic secondary 1-arylethan-1-ols. The influence of various process parameters such as temperature, flow rate and substrate concentration upon the biocatalyst efficiency and selectivity in the kinetic resolution of rac-1-phenylethan-1-ol was investigated and the conditions for the highest productivity were determined. The long-term activity and selectivity of the biocatalyst were preserved, enabling hundred gram scale resolution of rac-1-phenylethan-1-ol with only ∼70 mg of biocatalyst.

Reaction Chemistry & Engineering is an interdisciplinary journal reporting cutting-edge research focused on enhancing the understanding and efficiency of reactions. Reaction engineering leverages the interface where fundamental molecular chemistry meets chemical engineering and technology. Challenges in chemistry can be overcome by the application of new technologies, while engineers may find improved solutions for process development from the latest developments in reaction chemistry. Reaction Chemistry & Engineering is a unique forum for researchers whose interests span the broad areas of chemical engineering and chemical sciences to come together in solving problems of importance to wider society. All papers should be written to be approachable by readers across the engineering and chemical sciences. Papers that consider multiple scales, from the laboratory up to and including plant scale, are particularly encouraged.
