This study examines the plastisphere-biofouling nexus through a PRISMA-guided systematic review, bibliometric mapping, narrative-quantitative synthesis, and conceptual evidence integration of studies published between 2015 and 2025. From 1,248 records identified in Web of Science Core Collection and Scopus, 124 primary studies were retained for comparative synthesis. The reviewed evidence shows that microplastics frequently support distinct biofilm-associated microbial communities, although reported patterns vary across polymer type, exposure duration, environmental setting, microbial method, and biofilm measurement approach. Proteobacteria and Bacteroidetes were repeatedly reported among dominant bacterial groups, while opportunistic genera such as Vibrio and Pseudoalteromonas were detected in some plastisphere biofilms. Evidence for polymer-specific microbial diversity, contaminant retention, and environmental-driver effects remains context-dependent. Biofilm-coated microplastics may modify contaminant interactions under specific conditions, but current evidence does not support universal contaminant enhancement, confirmed pathogen transmission, or direct human health risk. This review identifies the plastisphere-biofouling nexus as an emerging ecological interface in coastal waters and highlights the need for standardized, field-relevant, and functionally validated studies.","PeriodicalId":8898,"journal":{"name":"Biofouling","volume":" ","pages":"752-770"},"PeriodicalIF":2.5,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148454332","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Treatment of pre-formed 24 h biofilms resulted in partial but significant biomass reduction, reaching up to ∼69% for P. fluorescens and ∼51% for S. epidermidis. Confocal microscopy confirmed pronounced structural disruption of mature biofilms following NADES exposure, particularly for CCLA.

However, the molecular mechanisms underlying this activity remain poorly understood. Here, we report that berberine effectively inhibits S. aureus biofilm formation with a minimum biofilm inhibitory concentration (MBIC) of 32 µg ml-1. XTT assays demonstrated a marked reduction in biofilm metabolic activity, while high-content screening (HCS) combined with three-dimensional reconstruction revealed significant decreases in biofilm biomass and thickness. Mechanistically, berberine selectively suppressed the production of key extracellular polymeric substance (EPS) components, particularly polysaccharide intercellular adhesin (PIA) and proteins, without significantly affecting extracellular DNA (eDNA) levels. Transcriptomic profiling integrated with protein-protein interaction (PPI) network modeling suggested that srrA, a response regulator within the two-component system, may serve as a central hub gene downregulated by berberine. Quantitative PCR (qPCR) further corroborated the altered expression of srrA and associated genes (walR, atpB, luxS, icaR). Collectively, these findings provide mechanistic insights into berberine's antibiofilm activity and point to srrA-mediated EPS regulation as a candidate pathway warranting further investigation.","PeriodicalId":8898,"journal":{"name":"Biofouling","volume":" ","pages":"619-632"},"PeriodicalIF":2.5,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148263148","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using standardised mesh substrates and DNA metabarcoding with the 18S rRNA gene, we characterised over 10,000 amplicon sequence variants (ASVs) across 216 samples, revealing 541 species from 249 taxonomic classes. Exposed sites exhibited marked seasonal contrasts: winter communities were dominated by hydroids (e.g. Coryne eximia), whereas summer assemblages were rich in amphipods (e.g. Jassa slatteryi). Sheltered sites showed more stable biomass and diversity but greater site-level variability, especially in summer. Temperature and wind fetch were strongly associated with community variation, with larger seasonal fluctuations observed under high-exposure conditions. Notably, several dominant species were non-native, underscoring the importance of early detection and tailored antifouling strategies.","PeriodicalId":8898,"journal":{"name":"Biofouling","volume":" ","pages":"571-587"},"PeriodicalIF":2.5,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148257199","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

R. officinalis and L. angustifolia oils also demonstrated notable antimicrobial effects, reducing bacterial viability, biofilm biomass, and metabolic activity, although effectiveness varied with species and biofilm structure.

The activity of these oils may be associated with disruption of bacterial membranes, biofilm architecture, and induction of oxidative stress.

This study investigated Bacillus subtilis strain engineered with three fluorescent reporter genes by integrating microscopic and macroscopic analyses to uncover the intrinsic mechanisms driving heterogeneous growth under competitive constraints. The results show that stress accumulation leads to the formation of a pronounced thickness peak in the interfacial region between two neighboring biofilms under strong competition (inoculation-center distance, d = 2 mm). Under nutrient-rich conditions, a ring-shaped elevation emerges approximately 4 mm from the colony center, providing an expanded spatial niche that facilitates bacterial survival. Self-healing rates of incisions at different locations of biofilms were compared to evaluate the effect of competition. The findings show that the self-healing capacity of biofilms in competitive environments is governed by both biofilm age and competitive intensity. Incorporating nutrient diffusion, environmental pressure, and phenotype-switching probabilities, a cellular automaton model was further developed to simulate the competitive growth of the biofilms.","PeriodicalId":8898,"journal":{"name":"Biofouling","volume":" ","pages":"588-601"},"PeriodicalIF":2.5,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148013385","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
