Gluconic acid production by bacteria to liberate phosphorus from insoluble phosphate complexes [PDF]

, 2015
Ten indigenous bacterial isolates were identified as efficient mineral phosphate solubilisers namely 7 strains of Klebsiella pneumoniae, 2 strains of Enterobacter aerogenes and 1 strain of Pseudomonas aeruginosa. All the ten strains were able to dissolve

Genetic Impacts on the Structure and Mechanics of Cellulose Made by Bacteria

Advanced Science, Volume 12, Issue 33, September 4, 2025.
A genetic mutation in a protease of a cellulose‐overproducing evolved bacterium significantly affects the proteome, structure, and mechanical properties of bio‐fabricated cellulose pellicles. By overexpressing synthase proteins that build the cellulose‐forming biological machinery of the cell, the evolved bacterium generates dense, stiff, and strong ...

Interactions of rare earth elements with living organisms and emerging biotechnical applications

PLANTS, PEOPLE, PLANET, Volume 7, Issue 5, Page 1251-1274, September 2025.
Rare earth elements (REEs) are critical resources required to achieve net‐zero carbon emission targets and energy security. However, rising demand for REEs coupled with significant extraction and processing challenges and geopolitical risks restricts access to REE resources.

The role of DJ-1 in enhancing mitochondrial quality control [PDF]

, 2013
Thesis (M.A.)--Boston UniversityDJ-1 is a cytosolic sensor for oxidative damage which acts on the Mitochondria. It works to curb the negative effects of high membrane potential in mitochondria, but the mechanism of action is still uncertain.

Exploring the Bacterial Microbiota of Seeds

Microbial Biotechnology, Volume 18, Issue 9, September 2025.
The presence of a functional bacterial microbiota in seeds is well established. However, the mechanisms underlying microbial entry into the propagule and its intracellular compartments remain largely unresolved. ABSTRACT The seed microbiota, a still underexplored component of plant–microbe interactions, plays a pivotal role in plant development and ...

Pyrroloquinoline Quinone Regulates Enteric Neurochemical Plasticity of Weaned Rats Challenged With Lipopolysaccharide

Frontiers in Neuroscience, 2022
The enteric nervous system (ENS) is important for the intestinal barrier to defend and regulate inflammation in the intestine. The aim of this study was to investigate the effect of pyrroloquinoline quinone (PQQ) on regulating neuropeptide secretion by ...

In Hyphomicrobium denitrificans Two Related Sulfane‐Sulfur Responsive Transcriptional Repressors Regulate Thiosulfate Oxidation and Have a Deep Impact on Nitrate Respiration and Anaerobic Biosyntheses

Molecular Microbiology, Volume 124, Issue 3, Page 204-220, September 2025.
In Hyphomicrobium denitrificans, the use of thiosulfate as a supplemental electron donor is regulated by two homologous sulfane‐sulfur responsive ArsR‐type transcriptional repressors, sHdrR and SoxR, that act cooperatively. Remarkably, the regulation by sHdrR/SoxR extends far beyond sulfur oxidation and deeply affects anaerobic metabolism, particularly
