“…85 The conditioning layer is important for biological sedimentation, which in turn depends on the roughness, hydrophobicity, and chemical nature of the initial matrix surface. 86 Because the attachment of organisms is governed by both environmental parameters and material properties, every species residing on a submerged surface is the product of selection processes and needs to be characterized deeply.…”

“…Due to the complex nature of biofilms, appropriate analytical techniques are required for characterizing them. 86 Staining assays utilizing dyes viz., crystal violet (CV), 1,9-dimethyl methylene blue (DMMB), and fluorescein-di-acetate (FDA) are the most common method for analysing biofilm. Another approach for studying biofilm utilizes molecular methods, like fluorescence in situ hybridization (FISH) and polymerase chain reaction (PCR), to identify the presence of specific gene sequences and to identify bacterial species associated with biofilm.…”

Microplastics are pollutants of emerging concern that have already gained significance in recent years because of their recalcitrant nature and their detrimental effects on living beings and the ecosystem. Due to their small size, microplastics are easily integrated into biogeochemical cycles and food webs, drastically affecting the environment. Our current knowledge on the interactions of microplastics with various components of ecosystems is limited; however, considering their potential long‐term impact, massive research efforts are underway to understand the environmental fate of microplastics and any possible strategies for remediation. In marine ecosystems, plastic surfaces are mostly colonized by microorganisms that form biofilms. Plastic‐biofilm interactions potentially influence the physical and chemical properties of the polymer, thereby leading to its degradation. Hence, to mitigate the foreseen nuisance of microplastics contamination, biofilms are being considered as potential candidates for the remediation of marine environments. Though the interactions between plastic and microbes are still inadequately understood, much of the research in the field is being focused on this aspect. In this review, we discuss several types and sources of microplastics, along with their trophic transfer and negative impacts on ecosystem. In addition, we focus on the current knowledge and explain the research gaps in understanding plastic‐microbe interactions in marine environments, while highlighting the role of biofilms in the degradation of microplastic debris. Finally, we comment on the future aspects and research priorities in this field to further elaborate the role of microorganisms in determining the fate of microplastics in aquatic ecosystems. © 2021 Society of Chemical Industry (SCI).
