ClearIntegration 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.
Multi-omics analysis reveals genes and metabolites involved in Bifidobacterium pseudocatenulatum biofilm formation
Multi-omics analysis of Bifidobacterium pseudocatenulatum biofilm formation on wheat fibers identified key genes and metabolites involved in biofilm development, providing insights into the molecular mechanisms of beneficial gut bacterial biofilm that could enhance probiotic function.
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.
Biofilms in plastisphere from freshwater wetlands: Biofilm formation, bacterial community assembly, and biogeochemical cycles
Researchers studied how bacteria form biofilms on microplastic surfaces in freshwater wetlands and found that these plastic-associated communities differ significantly from natural soil bacteria. The microplastic biofilms had lower diversity but higher activity in carbon processing and nitrogen cycling genes. This means microplastics in wetlands can alter natural nutrient cycles, potentially affecting water quality in ecosystems that many communities rely on.
Impact of microplastics on the intestinal microbiota: A systematic review of preclinical evidence
Across 28 preclinical studies, microplastics triggered intestinal dysbiosis characterized by increased Firmicutes and Proteobacteria and decreased Bacteroidetes, while increasing gut permeability and elevating pro-inflammatory cytokines including IL-1β, TNF-α, and IL-6.
Microplastic biofilms as potential hotspots for plastic biodegradation and nitrogen cycling: a metagenomic perspective
Researchers used genetic analysis to study the microbial communities that form biofilms on different types of microplastics in an estuarine environment. They found that these plastic-associated communities contained genes for both plastic degradation and nitrogen cycling, suggesting the biofilms may play dual roles in the ecosystem. The study indicates that microplastic surfaces in waterways create unique microbial habitats that could influence both pollution breakdown and nutrient processing.
A probiotic for preventing microplastic toxicity: Clostridium dalinum mitigates microplastic-induced damage via microbiota-metabolism-barrier interactions
Using metagenomics and metabolomics, this study found that the probiotic bacterium Clostridium dalinum reduced microplastic-induced gut damage in mice by modulating gut microbiota composition, metabolic pathways, and intestinal barrier integrity.
Exploring the Crucial Role of the Gut Microbiome in Advancing Food Processing Technologies
This review explores the role of gut microbiome composition in food processing and technology development, examining how microbial communities influence fermentation, nutrient bioavailability, and food safety, with implications for probiotic and prebiotic product design.
Biodegradation of microplastic by probiotic bifidobacterium
Researchers found that probiotic Bifidobacterium infantis can biodegrade microplastics, demonstrating a novel microbial approach to addressing plastic pollution using a gut-resident bacterium known for regulating intestinal microbiota.
The microplastic-crisis: Role of bacteria in fighting microplastic-effects in the digestive system
This review examines how microplastics affect the human digestive system and explores whether certain bacteria could help counteract the damage. Microplastics disrupt the gut by altering microbial communities, interfering with digestive enzymes, and damaging the protective mucus lining. The authors highlight the potential for probiotic bacteria to bind to microplastics, reduce inflammation, and help repair the gut environment, offering a possible protective strategy against microplastic-related digestive harm.
Exploring the Composition and Functions of Plastic Microbiome Using Whole-Genome Sequencing
Whole-genome sequencing of microbial biofilms on four types of marine microplastics revealed that plastic surfaces harbor distinct microbial communities with unique functional potential, including enrichment of Vibrio species with pathogenic and plastic-degrading capabilities.
New insight into the effect of microplastics on antibiotic resistance and bacterial community of biofilm
Researchers found that different types of microplastics promote distinct biofilm communities and enhance antibiotic resistance gene proliferation compared to natural substrates, suggesting microplastics serve as unique platforms for the spread of antimicrobial resistance.
Early stage of biofilm assembly on microplastics is structured by substrate size and bacterial motility
Researchers found that early-stage biofilm assembly on microplastics is strongly influenced by substrate size, with 0.3-mm particles harboring distinct bacterial communities enriched in motility and chemotaxis genes compared to larger 3-mm microplastics.
Biofilm formation on microplastics and interactions with antibiotics, antibiotic resistance genes and pathogens in aquatic environment
This review explains how microplastics in waterways develop bacterial biofilms on their surfaces that can harbor antibiotic-resistant bacteria and help spread antibiotic resistance genes to new environments. This is concerning for human health because these resistant microbes could eventually reach people through drinking water or seafood consumption.
Structural and Functional Characteristics of Microplastic Associated Biofilms in Response to Temporal Dynamics and Polymer Types
Researchers found that biofilm structural and functional characteristics on microplastics differ significantly depending on polymer type (polyethylene, polypropylene, and polystyrene) and change over time, with implications for understanding microbial colonization and the plastisphere.
Colonization characteristics and surface effects of microplastic biofilms: Implications for environmental behavior of typical pollutants
This review examines how bacteria colonize microplastic surfaces in water, forming biofilms that change how the plastics behave in the environment. These biofilms alter the surface properties of microplastics and affect how they absorb and transport heavy metals and other pollutants. Understanding biofilm formation on microplastics is important because it can make the particles more dangerous by concentrating toxic substances that could eventually enter the food chain.
A review on microbial-biofilm mediated mechanisms in marine microplastics degradation
This review examines how microbial biofilms form on microplastics in marine environments and their potential role in degrading these persistent pollutants. Researchers found that plastic-associated biofilm communities are diverse and influenced by factors such as polymer type, particle size, and seasonal conditions. The study identifies knowledge gaps in understanding how bacterial and fungal communities on microplastics may contribute to their breakdown in ocean environments.
Quantitative evaluation of microplastic interference with gut microbiota: Identifying sensitive indicators and key factors
This meta-analysis combined with machine learning found that the Firmicutes-to-Bacteroidetes ratio is the most sensitive biomarker of microplastic-induced gut microbiome disruption, with exposure concentration, particle size, and duration as the key drivers. The resulting predictive model (R=0.91) offers a quantitative tool for assessing gastrointestinal harm from microplastic exposure.

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.
