Quorum Sensing: Not Just a Bridge Between Bacteria
Summary
This review covers quorum sensing -- the chemical communication system bacteria use to coordinate group behavior -- and how it can be disrupted to fight infections and prevent harmful biofilm formation. The paper notes that microplastics are among the materials being explored to modulate these bacterial communication systems, which is relevant because bacteria colonizing microplastic surfaces in the environment may use quorum sensing to form biofilms that affect ecosystems and human health.
The study of quorum sensing (QS) has gained critical importance, offering insights into bacterial and microorganism communication. QS, regulated by autoinducers, synchronizes collective bacterial behaviors across diverse chemical signals and target genes. This review highlights innovative approaches to regulating QS, emphasizing the potential of quorum quenching and QS inhibitors to mitigate bacterial pathogenicity. These strategies have shown promise in aquaculture and plant resistance, disrupting QS pathways to combat infections. QS also provides opportunities for developing biosensors for early disease detection and preventing biofilm formation, which is critical to overcoming antimicrobial resistance. The applications of QS extend to cancer therapy, with targeted drug delivery systems utilizing QS mechanisms. Advancements in QS regulation, such as the use of nanomaterials, hydrogels, and microplastics, provide novel methods to modulate QS systems. This review explores the latest developments in QS, recognizing its significance in controlling bacterial behavior and its broad impacts on human health and disease management. Integrating these insights into therapeutic strategies and diagnostics represents a pivotal opportunity for medical progress.

Quorum Sensing Regulates Bacterial Processes That Play a Major Role in Marine Biogeochemical Cycles
This review synthesizes knowledge of quorum sensing in marine bacteria, examining how cell-to-cell chemical communication coordinates bacterial behaviors including biofilm formation, bioluminescence, and organic matter cycling that drive marine biogeochemical processes. The authors identify quorum sensing disruption as an understudied consequence of chemical pollution, with potential to alter nutrient cycling in ocean ecosystems.
Quorum sensing bacteria in microplastics epiphytic biofilms and their biological characteristics which potentially impact marine ecosystem
Researchers collected microplastics from the ocean and characterised the quorum-sensing bacteria living in their biofilms — microbes that communicate chemically to coordinate group behaviours like biofilm formation and antibiotic production. Eight different quorum-sensing bacterial strains were isolated from polypropylene and PVC microplastics, and their signalling molecules (AHLs) were profiled. The findings show that microplastics act as rafts dispersing complex microbial communities, including potentially harmful antibiotic-producing and biofilm-forming bacteria, across the global ocean.
[Influence of Polystyrene Microplastics on the Formation and Structural Change of Pseudomonas aeruginosa Biofilm].
Laboratory experiments exposing Pseudomonas aeruginosa — a medically significant opportunistic pathogen — to polystyrene microplastics found that MPs inhibited biofilm formation, with smaller particles (0.1 µm) causing stronger inhibition by disrupting the quorum sensing communication system that bacteria use to coordinate behavior. Microplastics caused physical damage to bacterial cells and reduced the expression of virulence-related genes. These findings suggest that environmental microplastic contamination could alter the behavior of pathogenic bacteria in ways that are difficult to predict.
Investigating Biofilms: Advanced Methods for Comprehending Microbial Behavior and Antibiotic Resistance
This review summarizes recent advances in biofilm research, focusing on how communities of microorganisms form protective layers on surfaces and become resistant to antibiotics. The sticky matrix that holds biofilms together plays a key role in spreading antibiotic resistance genes between bacteria. While not directly about microplastics, the findings are relevant because microplastics in the environment serve as surfaces where these resistant biofilms can form and spread.
Adaptive resistance and defense evolution in microplastics-mediated biological exposure interfaces in municipal wastewater treatment systems
Researchers studied how microplastic surfaces in municipal wastewater treatment systems promote the development of antimicrobial resistance. The study found that PET, polyethylene, and polypropylene microplastics trigger quorum sensing-driven resistance evolution in microbial biofilms, enhancing the expression of genes related to extracellular polymeric substances and potentially contributing to the spread of antibiotic resistance.
