ClearA comparative whole-genome approach identifies bacterial traits for marine microbial interactions
Researchers analyzed the complete genomes of 473 marine bacterial species to map out which interaction traits — like producing vitamins, growth hormones, or iron-grabbing compounds — each species carries. They found that specific bacterial groups are wired to interact more with each other and with algae, creating a genomic atlas that helps explain how ocean microbial communities assemble and function.
Novel functional insights into the microbiome inhabiting marine plastic debris: critical considerations to counteract the challenges of thin biofilms using multi-omics and comparative metaproteomics.
Researchers developed a comprehensive metaproteomics approach to study the microbial communities living on the surface of marine plastic debris, known as the plastisphere. The study reveals how microbes on plastic interact with each other and their environment, with implications for understanding how plastic-colonizing bacteria spread through the ocean.
Novel functional insights into the microbiome inhabiting marine plastic debris: critical considerations to counteract the challenges of thin biofilms using multi-omics and comparative metaproteomics
Researchers used advanced multi-omics techniques — simultaneously analyzing the DNA, proteins, and metabolic activity of microbes — to study the complex communities of bacteria and other microorganisms that colonize marine plastic debris (the "plastisphere"). The work reveals new ecological functions of these microbial films beyond plastic breakdown, including potential biotechnology applications and risks from pathogen hitchhiking on ocean plastic.

Beach wracks microbiome and its putative function in plastic polluted Mediterranean marine ecosystem
This study examined the microbial communities living on beach debris, including seagrass and plastic waste, along Mediterranean coastlines. Researchers found that while the bacterial communities on plastics were shaped more by beach conditions than by the type of plastic, these biofilms contained both plastic-degrading bacteria and potential human pathogens.
Genomic and proteomic profiles of biofilms on microplastics are decoupled from artificial surface properties
Genomic and proteomic analysis of biofilms on marine microplastics showed that community composition and functional profiles were primarily shaped by environmental conditions rather than the specific surface properties of the plastic substrate.
The structure and assembly mechanisms of plastisphere microbial community in natural marine environment
Researchers investigated how microbial communities colonize different types of microplastic surfaces in natural marine environments over an eight-week period. They found that the composition of these plastic-associated microbial communities, known as the plastisphere, was shaped more by environmental conditions and time than by the specific type of plastic. The study provides new understanding of the ecological processes governing how microorganisms assemble on ocean plastic debris.
Metagenome analysis of a soil and marine environment
This metagenomics thesis analyzed microbial communities on marine microplastics and in plant root zones, finding that the biofilm on plastic particles includes bacteria that may be capable of plastic degradation.
