Heterologous expression of Aspergillus terreus fructosyltransferase in Kluyveromyces lactis

New Biotechnology, 2016
Fructo-oligosaccharides are prebiotic and hypocaloric sweeteners that are usually extracted from chicory. They can also be produced from sucrose using fructosyltransferases, but the only commercial enzyme suitable for this purpose is Pectinex Ultra, which is produced with Aspergillus aculeatus.

Immobilization of α-amylase from anoxybacillus sp. SK3-4 on relizyme and immobead supports [PDF]

, 2016
α-Amylase from Anoxybacillus sp. SK3-4 (ASKA) is a thermostable enzyme that produces a high level of maltose from starches. A truncated ASKA (TASKA) variant with improved expression and purification efficiency was characterized in an earlier study.

In vitro binding interactions of oral bacteria with immobilized fructosyltransferase [PDF]

Journal of Applied Microbiology, 2006
The objective of the present study was to explore the role of immobilized fructosyltransferase (FTF) in adhesion process.We investigated real-time biospecific interactions between several types of oral bacteria and recombinant FTF immobilized on a biosensor chip, using surface plasmon resonance technology.

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).
