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.
Biofilm matrix cloaks bacterial quorum sensing chemoattractants from predator detection
Researchers found that bacterial biofilm matrix physically sequesters quorum sensing chemoattractant molecules, preventing detection by predatory bacterivores and providing the biofilm community with a chemical camouflage against grazing pressure.

Biofilm-mediated bioremediation of xenobiotics and heavy metals: a comprehensive review of microbial ecology, molecular mechanisms, and emerging biotechnological applications
This review explores how bacterial biofilms can be used to break down environmental pollutants, including heavy metals, pesticides, oil spills, and microplastics. Researchers found that the unique structure of biofilms gives them superior pollutant-degrading abilities compared to free-floating bacteria, and new advances like CRISPR gene editing and nanoparticle integration are making them even more effective. The study suggests that biofilm-based approaches offer a cost-effective and environmentally friendly way to tackle a wide range of contamination problems.
Factors Affecting Biofilm Formation and the Effects of These Factors on Bacteria

The Influence of Coalescent Microbiotic Particles From Water and Soil on the Evolution and Spread of Antimicrobial Resistance
This review examines how microbiotic particles in water and soil serve as hotspots for bacterial interactions, facilitating the evolution and horizontal transfer of antimicrobial resistance genes between ecologically distant bacterial species through biofilm formation on particle surfaces.
A Bibliography Study of Biofilm Life Cycle
This bibliography study reviews the biofilm life cycle -- encompassing initial attachment, irreversible attachment, maturation, and dispersal -- and its implications for medicine, environmental science, and industrial applications. The review synthesizes key literature on the molecular and ecological mechanisms driving biofilm formation and identifies research gaps relevant to biofilm management and control.
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.
Phylogenetic Constitution and Survival of Microbial Biofilms Formed on the Surface of Polyethylene Composites Protected with Polyguanidine Biocides
Researchers fabricated polyethylene composites containing immobilized polyguanidine biocides and tested their effectiveness against multispecies microbial biofilms reconstructed from environmental isolates. Polyguanidine biocide suppressed binary and multispecies biofilm growth with a cumulative effect over time, disrupting dense three-dimensional biofilm structures primarily during later formation stages, though cooperative interactions within binary biofilms reduced biocide effectiveness.
The Importance of Biofilms to the Fate and Effects of Microplastics
This review examines how biofilms — communities of microorganisms that form on microplastic surfaces — affect the fate and ecological effects of plastic pollution. Biofilm formation alters how microplastics are transported, ingested, and degraded in the environment, and the plastisphere can harbor pathogens and antibiotic-resistant bacteria that may pose risks to human health.

Integration of Transcriptome and Metabolome Reveals the Genes and Metabolites Involved in Bifidobacterium bifidum Biofilm Formation
Transcriptome and metabolome analysis of Bifidobacterium bifidum biofilm formation identified key genes and metabolic pathways involved in surface attachment, finding that sugar metabolism, stress response genes, and specific surface proteins are upregulated in biofilm-forming cells compared to planktonic cultures.
Genomic and proteomic profiles of biofilms on microplastics are decoupled from artificial surface properties
Genomic and proteomic analysis of biofilms on marine microplastics showed that community composition and functional profiles were primarily shaped by environmental conditions rather than the specific surface properties of the plastic substrate.
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.
Marine microbial biofilms on diverse abiotic surfaces
This review provides an overview of how microbial biofilms form on various non-living surfaces in the ocean, including microplastics, seafloor sediments, and submerged structures. Researchers describe how these surface-attached microbial communities have unique compositions and functions that influence ocean ecology and biochemical processes. The study also examines how biofilms contribute to biocorrosion and biofouling, highlighting their broad significance for both natural marine systems and human-built infrastructure.
Quorum Sensing: Not Just a Bridge Between Bacteria
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.
