“…Further, the DA analyses were carried out to nd the in uence of environment on the abundance of taxa. The microbial composition is known to be in uenced by polymer types (Song et al 2023). Also, sequencing depth is a serious concern, which can introduce bias in microbiome studies (Ramakodi 2021b(Ramakodi , 2021a).…”

Microplastics (MPs) are a potential threat to the marine environment and its associated ecosystem functions. Earlier investigations revealed that the microbiome plays a crucial role in deciding the fate of MPs in the environment. Further studies also highlighted the influences of environment and polymer types on the plastisphere microbiome. Nevertheless, the major factor that determines the plastisphere microbiome remains elusive. Thus, we examined the publicly available marine plastisphere data generated from polyethylene (PE), polypropylene (PP), and polystyrene (PS), collected from three different locations to identify the importance of environment and /or polymer types in shaping the microbiome. The beta diversity analyses showed a clear distinction between samples collected from different locations. The PERMANOVA results illustrated a significant influence of environment and sample type (control/PE/PP/PS) on the microbial communities. However, the influence of sample type on microbial diversity was not significant (P-value>0.05) when the control samples were removed from the dataset but the environment remained a significant factor (P-value<0.05). Further, the differential abundance analyses explicitly showed the abundance of several taxa to be significantly influenced (adjusted P-value<0.05) by the locations than the polymer types. Thus, this study suggests that both the surrounding environment and polymer types determine the microbial communities on marine MPs but the role of environment in shaping the microbial composition is greater than that of polymer types.

“…Microscopy observations indicated that freshwater eukaryotic microbes of various trophic levels may represent a significant portion of plastisphere biodiversity ( Carson et al, 2013 ; Oberbeckmann et al, 2014 ; Bryant et al, 2016 ; Masó et al, 2016 ), although high-throughput sequencing data are still limited ( Kettner et al, 2017 ; Bhagwat et al, 2021 ; González-Pleiter et al, 2021 ; Li et al, 2021 ; Wang et al, 2021 ; Weig et al, 2021 ; Xue et al, 2021 ; Chaudhary et al, 2022 ; Di Pippo et al, 2022 ; Li W. et al, 2023 ; Martínez-Campos et al, 2023 ; Miao et al, 2023 ; Song et al, 2023 ; Xu et al, 2024 ; Zhang et al, 2024 ). Different taxa of primary producers (Chlorophyta, Charophyta, Bacillariophyta), primary/secondary consumers (Peritrichia, Oligotrichia), mixotrophs (Dinophyceaea), saprotrophic/parasitic fungi (Cryptomycota, Peronosperales, Oomycetes), and metazoan consumers were retrieved ( Table 1 ).…”

“…Several studies have shown that the presence of taxa associated with the biodegradation process is strictly connected to environmental factors such as light exposure (including UV radiation), heat, humidity, absorbed chemicals, pH, and oxygen levels, depending on the specific sampling sites ( Tiwari et al, 2020 ; Yuan et al, 2020 ; Martínez-Campos et al, 2021 ; Vincent et al, 2022 ; Li W. et al, 2023 ). However, although mediated by biofilm composition and development ( Miao et al, 2021 ; for further details see Sun et al, 2023 ), plastic polymer type and properties as surface morphology, topography, hydrophobicity, electric charge distribution, molecular weight, mobility, crystallinity, types of functional groups, additives, and plasticizers were likely the main abiotic factors affecting the overall biodegradation process ( Tiwari et al, 2020 ; Yuan et al, 2020 ; Song et al, 2023 ).…”

The plastisphere, a unique microbial biofilm community colonizing plastic debris and microplastics (MPs) in aquatic environments, has attracted increasing attention owing to its ecological and public health implications. This review consolidates current state of knowledge on freshwater plastisphere, focussing on its biodiversity, community assembly, and interactions with environmental factors. Current biomolecular approaches revealed a variety of prokaryotic and eukaryotic taxa associated with plastic surfaces. Despite their ecological importance, the presence of potentially pathogenic bacteria and mobile genetic elements (i.e., antibiotic resistance genes) raises concerns for ecosystem and human health. However, the extent of these risks and their implications remain unclear. Advanced sequencing technologies are promising for elucidating the functions of plastisphere, particularly in plastic biodegradation processes. Overall, this review emphasizes the need for comprehensive studies to understand plastisphere dynamics in freshwater and to support effective management strategies to mitigate the impact of plastic pollution on freshwater resources.

“…However, low abundancies of plastic-specific OTUs were detected in a large analysis of marine biofilms on plastic ( Scales et al, 2021 ) but this seems to be restricted to the beginning of biofilm formation as plastic surfaces are being masked by biofilms with time. Additionally, nutrient availability may influence the structure of biofilm communities on plastic ( Song et al, 2023 ).…”

The environmental fate of plastic particles in water bodies is influenced by microbial biofilm formation. Invertebrate grazers may be affected when foraging biofilms on plastics compared to biofilms on natural substrata but the mechanistic basis for these effects is unknown. For analyzing these effects in ecotoxicological assays stable and reproducible biofilm communities are required that are related to the environmental site of interest. Here, a defined biofilm community was established and used to perform grazing experiments with a freshwater snail. For this, snippets of different plastic materials were incubated in the photic zone of three different freshwater sites. Amplicon sequencing of biofilms formed on these snippets showed that the site of incubation and not the plastic material dominated the microbial community composition. From these biofilms, individual microbial strains as well as photoautotrophic consortia were isolated; these consortia consisted of heterotrophic bacteria that were apparently nourished by microalga. While biofilms formed by defined dual cultures of a microalga and an Alphaproteobacterium were not accepted by the snail P. fontinalis, a photoautotrophic consortium (Co_3) sustained growth and metabolism of this grazer. Amplicon sequencing revealed that consortium Co_3, which could be stably maintained on solid medium under photoautotrophic conditions, reproducibly formed biofilms of a defined composition on three different plastic materials and on glass surfaces. In conclusion, our study shows that the generation of domesticated photoautotrophic microbial communities is a valid novel approach for establishing laboratory ecotoxicological assays with higher environmental relevance than those based on defined microbiota.
