Exploring the Diversity of Sugar Compounds in Healthy, Prediabetic, and Diabetic Volunteers

Molecular Nutrition &Food Research, Volume 64, Issue 9, May 2020., 2020
A pilot study with a broad sugar profiling analysis during an oral glucose tolerance test (OGTT) in the healthy and diabetic state is performed. Overall, 40 sugar compounds, including rare sugars, are detected in human plasma. A range of sugars reveal similar characteristic changes as glucose during an OGTT.

Update of the list of QPS‐recommended biological agents intentionally added to food or feed as notified to EFSA 11: suitability of taxonomic units notified to EFSA until September 2019

EFSA Journal, Volume 18, Issue 2, February 2020., 2020
Abstract Qualified presumption of safety (QPS) was developed to provide a generic safety evaluation for biological agents to support EFSA's Scientific Panels. The taxonomic identity, body of knowledge, safety concerns and antimicrobial resistance are assessed.

Purification and Characterization of D-psicose 3 Epimerase (DPEase) From Escherichia coli BL21 (DE3) pET21b dpe

Pakistan Journal of Biological Sciences, 2020
The DPEase enzyme from Agrobacterium tumefaciens is more efficient and has a high activity in D-fructose. The dpe gene has been successfully cloned to Escherichia coli BL21 (DE3) pET-21b dpe but the enzyme has not been purified and its character is unknown. The intent of this study was to purify and assign of DPEase enzyme by recombinant E.

Immobilization of Clostridium cellulolyticum d‑Psicose 3‑Epimerase on Artificial Oil Bodies

, 2016
The rare sugar d-psicose possesses several fundamental biological functions. d-Psicose 3-epimerase from Clostridium cellulolyticum (CC-DPEase) has considerable potential for use in d-psicose production.

Update: Enzymatische Synthese für industrielle Anwendungen

Angewandte Chemie, Volume 137, Issue 27, July 1, 2025.
Die Biokatalyse hat sich zu einer nachhaltigen und wettbewerbsfähigen Alternative zur herkömmlichen chemischen Synthese entwickelt und ermöglicht die enzymbasierte Herstellung nicht nur von chemischen Grundstoffen, sondern auch von (nicht natürlichen) Aminosäuren, (seltenen) Zuckern und synthetischen Nukleotiden.

Update of the list of qualified presumption of safety (QPS) recommended microbiological agents intentionally added to food or feed as notified to EFSA 21: Suitability of taxonomic units notified to EFSA until September 2024

EFSA Journal, Volume 23, Issue 1, January 2025.
Abstract The qualified presumption of safety (QPS) process was developed to provide a safety assessment approach for microorganisms intended for use in food or feed chains. In the period covered by this Statement, no new information was found that would change the status of previously recommended QPS taxonomic units (TUs).
