Random Mutagenesis in Porphyromonas gingivalis Enables Isolation of Mutants With Enhanced Secreted Protease Activity

Molecular Oral Microbiology, Volume 41, Issue 3, Page 158-164, June 2026.
ABSTRACT Porphyromonas gingivalis is a key pathogen in periodontitis, with secreted proteases as major virulence factors. We developed a screening method to generate and identify P. gingivalis mutants with elevated protease activity. Mutations were induced using the mutagens 2,6‐diaminopurine (2,6‐DAP) or ethyl methanesulfonate (EMS), and the ...

Effect of Mentha piperita Essential Oil and Its Nanoemulsion on Microbial Growth, Physicochemical, and Organoleptic Properties of Mango Yogurt During Refrigerated Storage

Food Science &Nutrition, Volume 14, Issue 5, May 2026.
Schematic illustration of “The effects of Mentha piperita essential oil and its nanoemulsion on microbial inhibition and quality preservation of mango yogurt during refrigerated storage”. ABSTRACT Fruit yogurts are more susceptible to microbial contamination than plain yogurts due to the incorporation of fruit ingredients, increasing the need for ...

The Rho-Dependent Transcription Termination Is Involved in Broad-Spectrum Antibiotic Susceptibility in Escherichia coli

Frontiers in Microbiology, 2020
One of the major ways of acquiring multidrug resistance in bacteria is via drug influx and efflux pathways. Here, we show that E. coli with compromised Rho-dependent transcription termination function has enhanced broad-spectrum antibiotic susceptibility,

Rhenium Complexes as Antimicrobial Agents

Helvetica Chimica Acta, Volume 109, Issue 5, May 2026.
Rhenium complexes are stepping into the fight against superbugs. Our new review explores how these metallic complexes could inspire the next generation of antimicrobial therapies. ABSTRACT The escalating crisis of antimicrobial resistance (AMR) necessitates the exploration of unconventional therapeutic scaffolds.

Yersinia pestisacrAB-tolCin Antibiotic Resistance and Virulence [PDF]

Antimicrobial Agents and Chemotherapy, 2012
ABSTRACTThe efflux pump AcrAB is important in the antibiotic resistance and virulence of several pathogenic bacteria. We report that deletion of theYersinia pestisAcrAB-TolC homolog leads to increased susceptibility to diverse substrates, including, though unlike inEscherichia coli, the aminoglycosides. Neither is theY.

Genome‐Scale Engineering Importing Property of Escherichia coli for Improving Production of 3‐Hydroxypropionic Acid

Microbial Biotechnology, Volume 19, Issue 5, May 2026.
We developed a systematic workflow to identify genes responsible for 3‐HP import by combining a genomic library with a fluorescent biosensor. Deleting the identified import‐related genes reduced product re‐uptake, successfully increasing 3‐HP titers by 21% and providing a new strategy for optimising microbial production platforms.

Kontrollierter Transport und lichtinduzierte Freisetzung von Magic Spot Nukleotiden in Escherichia coli

Angewandte Chemie, Volume 138, Issue 15, 6 April 2026.
We synthesized photocaged, clickable and isotope‐labeled “magic spot” Nucleotides and delivered them into Escherichia coli comparing different approaches. Light‐controlled release inside living cells enabled tracking of their conversion from pppGpp to ppGpp by capillary electrophoresis mass spectrometry and revealed their impact on the growth rate of a

Structural shifts in TolC facilitate Efflux-Mediated β-lactam resistance

Communications Biology
Efflux-mediated β-lactam resistance is a major public health concern, reducing the effectiveness of β-lactam antibiotics against many bacteria. Structural analyses show the efflux protein TolC in Gram-negative bacteria acts as a channel for antibiotics ...
