“…Previous studies have shown that the phylum Campylobacterota is among those microorganisms that may possess the capability to degrade MPs, potentially utilizing the plastic particles as a growth substrate. The other abundant phyla were found as Bacteroidetes at 15.72%, Firmicutes at 11.76%, and Proteobacteria at 7.95%, this finding is consistent with previous investigations that have characterized microbial communities inhabiting the surfaces of marine MPs [ 18 , 19 ]. In addition, species within the phyla Proteobacteria and Bacteroidetes have been identified as pivotal group in the initial colonization of plastic surfaces in marine [ 20 ].…”

“…In contrast to phylum Proteobacteria (7.95%) of the biofilm on M_MP, Proteobacteria was the most dominant phylum of the plastisphere with a substantial abundance of 74.35% in F_MP. Bacteroidetes (10.75%), Actinobacteria ( 6.5%), Planctomycetota (3.88%), Firmicutes (2%), and Verrucomicrobiota (1.33%), consistent with previous studies investigating microbial diversity of biofilms on MPs on freshwater [ 19 , 24 ]. The prevalence of these phyla was anticipated, as they are commonly distributed throughout the environment.…”

Microplastics (MPs) are major concern due to their potential harm to ecosystems and most research has focused on their presence and fate, with limited attention to their biodegradation in aquatic ecosystems. Nevertheless, MPs act as hotspots for the colonization by a diverse range of microorganisms that can adhere to plastic surfaces, resulting in the subsequent formation of biofilms—a potential threat especially in terms of pathogenicity. This study employed 16S rRNA and 18S rRNA sequencing metagenomic analyses to investigate microbial communities within biofilms on plastic materials exposed to long‐term marine and freshwater environments. Three Arcobacter species (Arcobacter nitrofigilis, Arcobacter acticola, and Arcobacter suis) emerged as dominant species in M_MP sample, while Flavobacterium tructae was the predominant species within the F_MP sample. The 18S rRNA sequencing revealed the presence of the fungal phylum Ascomycota and the microalgal species Pseudocharaciopsis ovalis in F_MP. Although, the primary species detected on M_MP and F_MP samples include bacteria previously implicated as pathogen, the predominant species identified in this study were unconnected to MP‐associated biofilms or MP degradation. Their presence constitutes a novel discovery, opening promising avenues for the exploration of their potential involvement in the biodegradation of MPs within aquatic environments.
