Quorum Sensing System of Ruegeria mobilis Rm01 Controls Lipase and Biofilm Formation

Frontiers in Microbiology, 2019
Quorum sensing (QS) promotes in situ extracellular enzyme (EE) activity via the exogenous signal N-acylhomoserine lactone (AHL), which facilitates marine particle degradation, but the species that engage in this regulatory mechanism remain unclear. Here,

Quorum-sensing effects in the antagonistic rhizosphere bacterium Serratia plymuthica HRO-C48 [PDF]

, 2017
The rhizosphere-associated bacterium Serratia plymuthica HRO-C48 is not only able to suppress symptoms caused by soil-borne pathogens but is also able to stimulate growth of plants.

In vivo and In vitro Interactions between Pseudomonas aeruginosa and Staphylococcus spp. [PDF]

, 2017
The significance of polymicrobial infections is increasingly being recognized especially in a biofilm context wherein multiple bacterial species—including both potential pathogens and members of the commensal flora—communicate, cooperate, and compete ...

N-acylhomoserine lactone regulation of adhesion and biofilm differentiation in Serratia marcescens MG1

, 2004
Serratia marcescens is an opportunistic pathogen involved in predominantly nosocomial infections, however, it is also implicated as a common cause of microbial keratitis. Since many S. marcecens strains are also resistant to multiple antibiotics, this organism represents a growing public health problem. S.

Degradation of pathogen quorum-sensing molecules by soil bacteria: a preventive and curative biological control mechanism [PDF]

, 2017
The plasmid pME6863, carrying the aiiA gene from the soil bacterium Bacillus sp. A24 that encodes a lactonase enzyme able to degrade N-acyl-homoserine lactones (AHLs), was introduced into the rhizosphere isolate Pseudomonas fluorescens P3. This strain is

Development of an ex vivo porcine lung model for studying growth, virulence, and signaling of Pseudomonas aeruginosa [PDF]

, 2014
Research into chronic infection by bacterial pathogens, such as Pseudomonas aeruginosa, uses various in vitro and live host models. While these have increased our understanding of pathogen growth, virulence, and evolution, each model has certain ...

The Function of Cyclo(Phe-Pro) in Gene Expression of Vibrio Harveyi [PDF]

, 2012
Vibrio harveyi is a bioluminescent bacterium and the organism in which quorum sensing was discovered. It was recently found that a class of molecules, cyclic dipeptides, may be a new kind of quorum sensing signal that may affect other species in the ...

Harnessing gravity-driven membranes in activated sludge bioreactors: Enhancing energy efficiency and mitigating biofouling via quorum quenching

npj Clean Water
This study developed a gravity-driven membrane bioreactor (GD-MBR) to reduce energy consumption in wastewater treatment. The system maintained a stable flux of 6 L/m2/h when treating high-organic wastewater loads (TOC: 270 mg/L, SS: 7,000 mg/L ...
