“…However, these results diverge from those of Sérvulo et al (2023), who reported stable communities over a 1-year immersion period. In terms of taxonomic diversity, Ascomycota dominate plastic-associated fungal communities, where other fungal phyla are also present (De Tender et al, 2017;Kettner et al, 2017;Lacerda et al, 2020Lacerda et al, , 2022Philippe et al, 2023;Sérvulo et al, 2023;Zeghal et al, 2021), which aligns with the general patterns in pelagic marine fungal diversity (Jones et al, 2019). Moreover, plastic-associated Chytridiomycota exhibit higher abundance during the autumn and winter seasons (Sérvulo et al, 2023) or at higher latitudes (Kettner et al, 2017;Kirstein et al, 2018).…”

Fungi in marine ecosystems play crucial roles as saprotrophs, parasites, and pathogens. The definition of marine fungi has evolved over the past century. Currently, “marine fungi” are defined as any fungi recovered repeatedly from marine habitats that are able to grow and/or sporulate in marine environments, form symbiotic relationships with other marine organisms, adapt and evolve at the genetic level, or are active metabolically in marine environments. While there are a number of recent reviews synthesizing our knowledge derived from over a century of research on marine fungi, this review article focuses on the state of knowledge on planktonic marine fungi from the coastal and open ocean, defined as fungi that are in suspension or attached to particles, substrates or in association with hosts in the pelagic zone of the ocean, and their roles in remineralization of organic matter and major biogeochemical cycles. This review differs from previous ones by focusing on biogeochemical impacts of planktonic marine fungi and methodological considerations for investigating their diversity and ecological functions. Importantly, we point out gaps in our knowledge and the potential methodological biases that might have contributed to these gaps. Finally, we highlight recommendations that will facilitate future studies of marine fungi. This article first provides a brief overview of the diversity of planktonic marine fungi, followed by a discussion of the biogeochemical impacts of planktonic marine fungi, and a wide range of methods that can be used to study marine fungi.

“…It was shown that as the plastic biofilm cover develops, the effect of the polymer type on the microbiome composition is weakening until it is almost unnoticeable [2, 17]. This notion was validated in a recent study that showed that the polymer type affects microbiome composition and metabolic functionality in early marine plastic communities but not mature communities [26].…”

“…While the composition of the plastic-attached microbiome differs from that of natural organic debris [13], the effect of the plastic polymer type remains elusive and often undetectable [8, 14-16]. A few studies showed polymer-based variations in the early marine plastic microbiome, a few days to several weeks old [17-22]. However, statistically valid colonization and succession signatures of individual species within a naturally developed biofilm are missing.…”

During the past decades since plastic was introduced to the world, marine microorganisms have been adapted for life on marine plastic debris, forming unique plastic-attached microbial communities. To date, little is known about the colonization and succession processes that take place on plastic surfaces in marine environments and how the plastic polymer type affects the plastic-attached microbiome composition. To address this knowledge gap, we examined the colonization and succession dynamics of marine bacteria on four common plastic polymers - PE, PP, PS, and PET-compared to glass and wood in a controlled seawater system under different temperatures. Using a simple experimental design, coupled with a long-read 16S rRNA metabarcoding pipeline and a set of complementary data analyses, we characterized the temporal trends in the composition of the bacterial microbiome developed on different surfaces over 2 - 90 days. By applying weighted gene co-expression network (WGCNA) analysis, we established co-occurrence networks and identified genera with specific succession signatures, significant enrichment on specific plastic polymers and/or strong intra-genus connections. Among them, members of genusAlcanivoraxwere significantly enriched on either PE or PP plastic surfaces as early as 2 days post-inoculation.Alcanivoraxcolonization preference to polyolefins was confirmed in colonization assays with pureAlcanivoraxstrains. Our research approach presented here may contribute to understanding how plastisphere communities are being formed and help identify taxa with specific adaptations to plastic surfaces.
