Sustainable Natural Product Glycosylation: A Critical Evaluation of Biocatalytic and Chemical Approaches. [PDF]

open access: yesChemSusChem
Developing a process to produce glycosylated natural products involves many decisions, and given the current climate crisis, the environmental impact of the various processes must be a major consideration. This review provides an overview of the various processes and a framework for which metrics should be quantified to select processes that are both ...

Food manufacturing processes and technical data used in the exposure assessment of food enzymes

open access: yesEFSA Journal, Volume 21, Issue 7, July 2023., 2023
Abstract Food enzymes are used for technical purposes in the production of food ingredients or foods‐as‐consumed. In the European Union, the safety of a food enzyme is evaluated by EFSA on the basis of a technical dossier provided by an applicant. Dietary exposure is an integral part of the risk assessment of food enzymes.

Update of the list of QPS‐recommended biological agents intentionally added to food or feed as notified to EFSA 12: suitability of taxonomic units notified to EFSA until March 2020

open access: yesEFSA Journal, Volume 18, Issue 7, July 2020., 2020
Abstract The qualified presumption of safety (QPS) was developed to provide a generic safety evaluation for biological agents to support EFSA's Scientific Panels. It is based on an assessment of the taxonomic identity, the body of knowledge, safety concerns and antimicrobial resistance.

Efficient Soluble Expression and Fermentation Conditions of D-Allulose 3-Epimerase in Escherichia coli

open access: yesShipin gongye ke-ji, 2022
The DAEase gene sequence derived from Clostridium bolteae ATCCBAA-613 was synthesized by codon optimization. Using pCold TF as the expression vector, the cold-shock promoter CspA induced the expression of the DAEase gene in Escherichia coli BL21(DE3) at ...

Enzyme Immobilization on Synthesized Nanoporous Silica Particles and their Application in a Bi‐enzymatic Reaction

open access: yesChemCatChem, Volume 12, Issue 8, Page 2245-2252, April 20, 2020., 2020
Different immobilization methods were evaluated for application of two biocatalysts in a cofactor dependent reaction. Promising immobilization and activity yields were obtained by covalent immobilization on synthesized hydrophilic silica particles. High reaction stabilities for the two immobilized enzymes resulted in a 10‐fold increase of the turnover ...
