Update of the list of qualified presumption of safety (QPS) recommended microbiological agents intentionally added to food or feed as notified to EFSA 20: Suitability of taxonomic units notified to EFSA until March 2024

open access: yesEFSA Journal, Volume 22, Issue 7, July 2024.
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 TUs. The TUs in the QPS list were updated based on a

Crystal structure of a glycoside hydrolase family 68 β-fructosyltransferase from Beijerinckia indica subsp. indica in complex with fructose

open access: yesBioscience, biotechnology and biochemistry, 2020
An enzyme belonging to glycoside hydrolase family 68 (GH68) from Beijerinckia indica subsp. indica NBRC 3744 was expressed in Escherichia coli. Biochemical characterization showed that the enzyme was identified to be a β-fructosyltransferase (BiBftA ...

Characterization of sucrose: sucrose fructosyltransferase from crested wheatgrass* [PDF]

open access: yesNew Phytologist, 1988
summaryBiosynthesis of the trisaccharide precursor of fructan occurs through the action of sucrose: sucrose fructosyltransferase (SST). This study defines the optimal conditions for in vitro SST and invertase activities from a crested wheatgrass hybrid developed from a cross between Agropyron cristatum (L.) Gaertn. ×A. desertorum (Fisch.

Cell‐type proteomic and metabolomic resolution of early and late grain filling stages of wheat endosperm

open access: yesPlant Biotechnology Journal, Volume 22, Issue 3, Page 555-571, March 2024.
Summary The nutritional value of wheat grains, particularly their protein and metabolite composition, is a result of the grain‐filling process, especially in the endosperm. Here, we employ laser microdissection (LMD) combined with shotgun proteomics and metabolomics to generate a cell type‐specific proteome and metabolome inventory of developing wheat ...

Pangenome Analysis of Helicobacter pylori Isolates from Selected Areas of Africa Indicated Diverse Antibiotic Resistance and Virulence Genes

open access: yesInternational Journal of Genomics, Volume 2024, Issue 1, 2024.
The challenge facing Helicobacter pylori (H. pylori) infection management in some parts of Africa is the evolution of drug‐resistant species, the lack of gold standard in diagnostic methods, and the ineffectiveness of current vaccines against the bacteria.

Expression analysis of a set of genes related to the ripening of bananas and mangoes [PDF]

open access: yes, 2009
During ripening many important physic-chemical changes contribute to fruit quality, and they are precisely determined by gene expression. Specific genes are essential to normal ripening; however, information on gene expression about the majority of ...

Development of Root Caries Associated With the Use of Sugar‐Free Nicotine Lozenges: A Long‐Term Case Report

open access: yesCase Reports in Dentistry, Volume 2024, Issue 1, 2024.
The authors present a case concerning an adult male patient who developed multiple sites of root caries adjacent to the area where he habitually held a sugar‐free nicotine lozenge that contained mannitol and maltodextrin. The root caries occurred despite the patient’s excellent oral hygiene, exemplary dietary habits, and clinically normal salivary flow.

Fructan biosynthesis and degradation as part of plant metabolism controlling sugar fluxes during durum wheat kernel maturation

open access: yesFrontiers in Plant Science, 2015
Wheat kernels contain fructans, fructose based oligosaccharides with prebiotic properties, in levels between 2 and 35 weight % depending on the developmental stage of the kernel.
