Quorum Sensing System of Rm01 Controls Lipase and Biofilm Formation.

Frontiers in microbiology
Quorum sensing (QS) promotes extracellular enzyme (EE) activity via the exogenous signal -acylhomoserine lactone (AHL), which facilitates marine particle degradation, but the species that engage in this regulatory mechanism remain unclear. Here, we ...

The Addition of Viriditec Aqueous Ozone to Peracetic Acid as an Antimicrobial Spray Increases Air Quality While Maintaining Typhimurium, Non-pathogenic , and Reduction on Whole Carcasses.

Frontiers in microbiology
Currently, the most utilized antimicrobial in processing facilities is peracetic acid, PAA; however, this chemical is increasingly recognized as a hazard to human health. Preliminary evidence suggests that ozone, when introduced in a specific manner,...

Low Abundances but High Growth Rates of Coastal Heterotrophic Bacteria in the Red Sea.

Frontiers in microbiology
Characterized by some of the highest naturally occurring sea surface temperatures, the Red Sea remains unexplored regarding the dynamics of heterotrophic prokaryotes. Over 16 months, we used flow cytometry to characterize the abundance and growth of ...

Extracellular Vesicles Released by () Promote Disease Progression and Induce the Production of Different Cytokines in Macrophages and B-1 Cells.

Frontiers in microbiology
The extracellular vesicles (EVs) released by can contribute to the establishment of infection and host immunomodulation. In this study, we characterized the shedding of EVs from promastigotes. This species is the causative agent of cutaneous leishm...

Insight to Improve α-L-Arabinofuranosidase Productivity in and Its Application on Corn Stover Degradation.

Frontiers in microbiology
α-L-arabinofuranosidase (ARA) with enhanced specific activity and in large amounts, is needed for a variety of industrial applications. To improve ARA production with engineered methylotrophic yeast , a genetically modified gene from ND-1 was inves...

Lipids, pH, and Their Interaction Affect the Inhibitory Effects of Carvacrol against Typhimurium PT4 and O157:H7.

Frontiers in microbiology
Although carvacrol (CAR) is considered an alternative antimicrobial for use in food, few is known about the influence of food-related parameters on its inhibitory effects against pathogens. This study assessed the influence of different amounts of pr...

Effects of Sub-lethal Concentrations of Silver Nanoparticles on a Simulated Intestinal Prokaryotic-Eukaryotic Interface.

Frontiers in microbiology
Nanotechnology applications are expected to bring a range of benefits to the food sector, aiming to provide better quality and conservation. In this research, the physiological response of both an mono-species biofilm and Caco-2 intestinal cells to ...

Transcriptional Modulation of Penicillin-Binding Protein 1b, Outer Membrane Protein P2 and Efflux Pump (AcrAB-TolC) during Heat Stress Is Correlated to Enhanced Bactericidal Action of Imipenem on Non-typeable .

Frontiers in microbiology
The purpose of the present study was to investigate the penicillin binding proteins (PBPs), drug influx and efflux modulations during heat stress and their effects on the bactericidal action of imipenem on non-typeable (NTHi). The two NTHi clinica...

Phytochemicals from Chi Flowers Reduce the Pyocyanin Production and Motility of PAO1.

Frontiers in microbiology
Chi, known as a medicinal and edible plant in China, exhibits multiple bioactivities, especially antibacterial activity. In this study, we investigated the inhibitory effects of the dichloromethane fraction (DF) of Chi flowers on the pyocyanin prod...

Autoinducer-2 Quorum Sensing Contributes to Regulation of Microcin PDI in .

Frontiers in microbiology
The quorum sensing (QS) signal molecule, autoinducer-2 (AI-2), reaches its maximum concentration during mid-to-late growth phase after which it quickly degrades during stationary phase. This pattern of AI-2 concentration coincides with the up- then ...
