Species‐Specific Optimisation and Environmental Regulation of Biofilm Formation in Enterobacter cloacae: Inhibitory Role of Glucose in Biofilm Development

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.
This study demonstrates that mild salinity stress (1%–2% NaCl) significantly enhances biofilm formation in Enterobacter cloacae. Using a standardised 96‐well microtiter plate assay, we optimised in vitro biofilm quantification and classification, providing a reproducible framework for studying environmental and clinical biofilm development mechanisms ...

Immune Evasion of Helicobacter pylori and Extra‐Gastric Cancer Risk

Journal of Gastroenterology and Hepatology, Volume 41, Issue 6, Page 1722-1742, June 2026.
ABSTRACT Helicobacter pylori (H. pylori) is a group 1 gastric carcinogen that plays a significant role in extra‐gastric digestive system cancers. H. pylori disrupts host cell homeostasis through expression of virulence factors leading to immune evasion as well as persistent gastric mucosal colonization. H. pylori infection has been shown to play a role

Tailoring Escherichia coli BL21 (DE3) for preferential xylose utilization via metabolic and regulatory engineering

Applied Microbiology and Biotechnology
Xylose is the most abundant pentose in nature. However, it is usually obtained in mixtures with glucose, leading to carbon catabolite repression in many microorganisms. Among E.

Bioconversion of carotenoids into high‐value crocins using a marine sponge carotenoid cleavage dioxygenase

New Phytologist, Volume 250, Issue 5, Page 3230-3246, June 2026.
Summary Carotenoids and apocarotenoids are widespread specialized metabolites, yet animals, including sponges, lack the ability to synthesize carotenoids de novo and must obtain them from dietary or microbial sources. The roles of carotenoid cleavage dioxygenases (CCDs) in marine animals remain largely unexplored. A CCD from the marine sponge Suberites

Role of glucose and CcpA in capsule expression and virulence of Streptococcus suis

, 2011
Streptococcus suis is one of the most important pathogens in pigs and is also an emerging zoonotic agent. After crossing the epithelial barrier, S. suis causes bacteraemia, resulting in meningitis, endocarditis and bronchopneumonia.

Catabolic regulation analysis of Escherichia coli and its crp, mlc, mgsA, pgi and ptsG mutants

Microbial Cell Factories, 2011
Background Most bacteria can use various compounds as carbon sources. These carbon sources can be either co-metabolized or sequentially metabolized, where the latter phenomenon typically occurs as catabolite repression.

Regulation of neuraminidase expression in Streptococcus pneumoniae

BMC Microbiology, 2012
Background Sialic acid (N-acetylneuraminic acid; NeuNAc) is one of the most important carbohydrates for Streptococcus pneumoniae due of its role as a carbon and energy source, receptor for adhesion and invasion and molecular signal for promotion of ...
