“…To date, many studies have explored the plastisphere in aquatic ecosystems such as oceans ( Delacuvellerie et al, 2022b ), lakes ( Di Pippo et al, 2022 ), and rivers ( Delacuvellerie et al, 2022a ), as well as in soil ecosystems such as farmlands ( Wang et al, 2022 ), mountains ( Rüthi et al, 2023 ), and landfills ( MacLean et al, 2021 ), using techniques such as amplicon sequencing and metagenome sequencing. These studies have analyzed the microbial community structures in the plastisphere and compared them to the microbial community structures in the surrounding environment from the same environmental source ( Zhang S. J. et al, 2022 ; Zhurina et al, 2022 ). Moreover, the formation of mature and stable biofilms on the surfaces of plastic debris is required for the establishment of the plastisphere and the gradual formation of biofilms reduces the hydrophobicity of plastic and alters its functional groups ( Tu et al, 2020 ; Du et al, 2022 ).…”

Numerous microorganisms and other invertebrates that are able to degrade polyethylene (PE) have been reported. However, studies on PE biodegradation are still limited due to its extreme stability and the lack of explicit insights into the mechanisms and efficient enzymes involved in its metabolism by microorganisms. In this review, current studies of PE biodegradation, including the fundamental stages, important microorganisms and enzymes, and functional microbial consortia, were examined. Considering the bottlenecks in the construction of PE-degrading consortia, a combination of top-down and bottom-up approaches is proposed to identify the mechanisms and metabolites of PE degradation, related enzymes, and efficient synthetic microbial consortia. In addition, the exploration of the plastisphere based on omics tools is proposed as a future principal research direction for the construction of synthetic microbial consortia for PE degradation. Combining chemical and biological upcycling processes for PE waste could be widely applied in various fields to promote a sustainable environment.

“…Many studies investigated biofouling communities developed on plastics floating in the oceans or deposited in sediments using metagenomic approaches. Due to limited space, we refer readers to reviews about this topic [ 78 , 79 , 80 ]. In general, the studies confirmed the presence of diverse and specific microbial communities associated with different types of plastic which were different from microbes in the water column.…”

Biofouling is the growth of organisms on wet surfaces. Biofouling includes micro- (bacteria and unicellular algae) and macrofouling (mussels, barnacles, tube worms, bryozoans, etc.) and is a major problem for industries. However, the settlement and growth of some biofouling species, like oysters and corals, can be desirable. Thus, it is important to understand the process of biofouling in detail. Modern “omic” techniques, such as metabolomics, metagenomics, transcriptomics, and proteomics, provide unique opportunities to study biofouling organisms and communities and investigate their metabolites and environmental interactions. In this review, we analyze the recent publications that employ metagenomic, metabolomic, and proteomic techniques for the investigation of biofouling and biofouling organisms. Specific emphasis is given to metagenomics, proteomics and publications using combinations of different “omics” techniques. Finally, this review presents the future outlook for the use of “omics” techniques in marine biofouling studies. Like all trans-disciplinary research, environmental “omics” is in its infancy and will advance rapidly as researchers develop the necessary expertise, theory, and technology.

“…A quantity of industrial and household water tanks, pipes and plumbing elements, elements of children's playgrounds and swimming pools are made of polyethylene. Although PE-based materials are highly resistant to microbial biocorrosion, they are susceptible to biofouling by multispecies microbial biofilms [1]. The formation of those biofilms might be an essential factor influencing the decomposition and overall damage sustained by those materials in both consumable products and packaging [2].…”

“…In addition, the formation of microbial biofilms on PE surfaces influences the state of ecosystems, as the microplastics can migrate over considerable distances (especially in hydro-and aerosphere) as a substrate for invasive species, including hazardous and pathogenic microorganisms, changing the cycle of biogenic elements and the composition of native microbiota [1].…”

A series of biocide-containing polyethylene composites were obtained using novel guanidine-containing copolymers immobilized on an inert mineral carrier. Multispecies microbial communities were isolated from the surface of polyethylene samples either incubated or found in the environment, and their taxonomic composition was determined. Biofilms reconstructed using microorganisms obtained from different ecotopes were shown to intensively foul polyethylene surfaces. The presence of polyguanidine biocide suppressed the growth and survival of both binary and multispecies biofilms, with a cumulative effect during long-term incubation. When microorganisms were co-cultivated in binary biofilms, the phenomenon of a decrease in biocide effectiveness was demonstrated. This protective effect is potentially based on cooperative interactions inside the binary biofilm community. Scanning electron microscopy showed a pronounced difference in the architecture of reconstructed biofilms incubated in the presence of biocide in comparison to control samples, where biocide suppressed the formation of dense and well-organized three-dimensional structures. Biofilm disruption by immobilized biocides occurred primarily during the later stages of biofilm formation, probably caused by polycation interaction with their negatively charged extracellular components.
