Crystal Structure of the Active Site Mutant Form of Soluble Fumarate Reductase, Osm1

Crystals, 2019
Soluble fumarate reductase is essential for survival under anaerobic conditions. This enzyme can maintain the redox balance in the cell by catalyzing the reduction of fumarate to succinate.

Incorporation of Cryptic Plasmid Energetics Improves Genome‐Scale Metabolic Predictions in Probiotic E. coli Nissle 1917

Microbial Biotechnology, Volume 19, Issue 5, May 2026.
This study presents the expansion of genome‐scale models of Escherichia coli Nissle 1917 to account for the metabolic cost of its cryptic plasmids. Through systematic comparison with previous reconstructions and validation against fluxomics datasets, the models improved accuracy in predicting growth and overall metabolic fluxes.

Time dynamics of the Bacillus cereus exoproteome are shaped by cellular oxidation

Frontiers in Microbiology, 2015
At low density, Bacillus cereus cells release a large variety of proteins into the extracellular medium when cultivated in pH-regulated, glucose-containing minimal medium, either in the presence or absence of oxygen. The majority of these exoproteins are

Engineering New‐to‐Nature Biological Pathways for β,γ‐Alkanediol Synthesis

Advanced Science, Volume 13, Issue 23, 23 April 2026.
β,γ‐Alkanediols are value‐added chemicals to be used as functional solvents, biofuels, and cosmetic components. This work demonstrates a carboligation‐mediated approach for synthesis of linear chain β,γ‐alkanediols in Escherichia coli, namely, hexane‐2,3‐diol (2,3‐HDO) and pentane‐2,3‐diol (2,3‐PDO). The engineered E. coli cells produce 152.2 mm (17.98

Prediction of organic acid concentration in BRS Capiaçu elephant grass silage

Grassland Science, Volume 72, Issue 2, Page 73-81, April 2026.
Abstract This study aimed to develop prediction models for organic acid concentrations in Capiaçu grass (Pennisetum purpureum Schum) silage, based on fermentation parameters and chemical composition. Data were obtained from an experiment that evaluated BRS (Brazil Seeds) Capiaçu grass silage with the inclusion of dehydrated cashew pseudofruit ...
