Functional and structural characterization of Hyp730, a highly conserved and dormancy‐specific hypothetical membrane protein

MicrobiologyOpen, 2021
Membrane proteins represent major drug targets, and the ability to determine their functions, structures, and conformational changes will significantly advance mechanistic approaches to both biotechnology and bioremediation, as well as the fight against ...

Ecofriendly synthesis of stabilized silver nanoparticles and the evaluation of their potential applications

Current Research in Green and Sustainable Chemistry, 2021
Herein, we report a simple and rapid microwave-assisted green synthesis of silver nanoparticles (AgNPs) using Phoenix Dactylifera L petiole wood extract (PDLPE) with a dual role as a reducing and stabilizing agent.

Transcription termination factor Rho is essential for Micrococcus luteus [PDF]

Journal of Bacteriology, 1997
The growth of Micrococcus luteus, a soil microorganism that belongs to the high-G+C gram-positive phylogenetic group, is prevented by bicyclomycin, an antibiotic that inhibits the activity of the M. luteus transcription termination factor Rho. A mutant that can grow in 0.3 mM bicyclomycin has a Rho that is insensitive to bicyclomycin and has the single

Risk Factors of Blood Culture Positivity and Mortality in Bloodstream Infections: A Population‐Based Study of Patients With B‐Cell Malignancies

European Journal of Haematology, Volume 117, Issue 4, Page 1061-1071, October 2026.
ABSTRACT Background Bloodstream infections remain a major cause of mortality among cancer patients. Pathogen surveillance and risk stratification tools are key to improved management. This study describes trends in causative pathogens and explores risk factors for positive blood cultures (PBCs) and post‐infection mortality in cancer patients.

Malaria mosquito antimicrobial defence requires immunity and detoxification gene regulation by Lola

Insect Molecular Biology, Volume 35, Issue 5, Page 576-593, October 2026.
Malaria mosquito antimicrobial defence requires upregulation of lola. Attenuation of lola in the midgut of Anopheles albimanus mosquitoes inhibits the upregulation of immunity genes induced by challenge. Putative target genes of the Lola transcription factor were revealed by lola attenuation, including Cecropin‐C, Draper, PPAF2, Clip‐domain serine ...

Incidence and Mortality of Community‐Acquired Sepsis or Bacteraemia in Patients With Alcohol‐Related Cirrhosis

Liver International, Volume 46, Issue 10, October 2026.
ABSTRACT Background & Aims Liver cirrhosis is associated with an increased risk of bacterial infections, but there is a lack of reliable population‐based data to quantify this risk. We examined the incidence and predictors of community‐acquired serious systemic infections.

Variances in cellular sedimentation behavior as an effective enrichment method of hydrocarbon-overproducing Micrococcus luteus strains

Biotechnology for Biofuels, 2018
Background Aliphatic hydrocarbons of microbial origin are highly interesting candidate biofuels because these molecules are identical or very similar to the main components of petroleum-based gasoline and diesel fuels. The high-GC Gram-positive bacterium

Clean Synthesis of N‐4‐Alkylamino‐7‐chloroquinoline Cyclic Imides: Influence of Lipophilicity on Antibacterial and Ecotoxicological Properties

Chemistry &Biodiversity, Volume 23, Issue 9, September 2026.
For series 2a–d, there appears to be optimal activity against Klebsiella pneumoniae when lipophilicity is intermediate (log P 2.64 for 2b). Similarly, for series 2e–g, activity against Pseudomonas aeruginosa, Staphylococcus aureus and Streptococcus mutans also increases (log P 3.71 for 2f).

Detecting Antibiotic Resistance in Strains of Selected Gram‐Negative Bacterial Species Using Raman Spectroscopy

Journal of Raman Spectroscopy, Volume 57, Issue 9, Page 1554-1564, September 2026.
Raman spectroscopy successfully identified antibiotic‐resistant Gram‐negative strains. Resistant strains of four bacterial species were discriminated from sensitive ones with 99.1% accuracy using PLS regression. The method allows for rapid, label‐free detection of antibiotic resistance.
