Phosphate-responsive ornithine lipid biosynthesis remodels outer membrane composition and contributes to polymyxin tolerance

This study identifies OlsF-dependent ornithine lipid biosynthesis as a phosphate-responsive pathway that remodels the outer membrane and enhances polymyxin tolerance in Enterobacterales.

The DUF998 family protein DrmA modulates cationic glycolipid levels and the emergence of high-level daptomycin resistance in Enterococcus faecalis

This study identifies DrmA, a DUF998 family protein, as a regulator of cationic glycolipid levels and a contributor to high-level daptomycin resistance in E. faecalis.

Isolation of bioconcrete-producing bacteria for urea-free marine applications

The paper isolates and characterizes marine bacteria capable of producing bioconcrete without urea, suitable for self-healing marine concrete structures.

Biosynthesis of glucosaminyl phosphatidylglycerol in Pseudomonas aeruginosa

This study identifies the biosynthetic genes for glucosaminyl phosphatidylglycerol (GlcN-PG) in Pseudomonas aeruginosa and demonstrates their role in its production and potential transport.

Synthesis of perfluorooctanoic acid-containing membrane lipids by human pathobionts

This study shows human gut bacteria can synthesize fluoroalkyl-containing membrane lipids in response to PFOA exposure, suggesting new pathways for PFAS bioaccumulation and host-microbe interactions.

Factors affecting CRISPR-Cas defense against antibiotic resistance plasmids harbored by Enterococcus faecalis laboratory model strains and clinical isolates

This study investigates how multiple plasmids in donor strains affect CRISPR-Cas defense against targeted plasmids in E. faecalis, showing that non-targeted plasmids like pTEF2 enhance conjugative transfer of CRISPR-targeted plasmids.

Biosynthesis of mitis group streptococcal glycolipids and their roles in physiology and antibiotic susceptibility

This study investigates the biosynthesis and roles of glycolipids in mitis group streptococci, showing their importance in virulence and antibiotic resistance.
