Researchers used high-throughput DNA sequencing to profile bacterial communities colonizing microplastics in the intertidal zone of China's Yangtze Estuary, finding that plastisphere community composition reflected the particles' sedimentary versus aquatic origins and included keystone taxa adapted to surface-colonization as well as potential pathogens hitchhiking on plastic surfaces.
Seasonal biofilm formation on floating microplastics in coastal waters of intensified marinculture area
Researchers investigated seasonal biofilm formation on floating polyethylene and polypropylene microplastics in four coastal mariculture zones in southeast China, finding that biofilm bacterial community composition differed less between winter and summer than the surrounding planktonic bacteria. The results suggest biofilms on microplastics provide a buffering microenvironment that stabilizes bacterial communities across seasons.
Marine microplastic-associated bacterial community succession in response to geography, exposure time, and plastic type in China's coastal seawaters
Researchers used high-throughput gene sequencing to track how microbial communities on polypropylene and polyvinyl chloride microplastics changed over a full year in Chinese coastal waters. They found that the composition of plastic-associated bacterial communities varied significantly across geographic locations and over time, with Alphaproteobacteria being consistently dominant. The study reveals that the plastisphere is a dynamic ecosystem shaped by both environmental conditions and the duration of exposure.
Bacterial Communities in Zostera marina Seagrass Beds of Northern China
Researchers characterized bacterial communities in Zostera marina seagrass beds in northern China, comparing microbiome composition between seagrass-associated and bare sediment sites. Seagrass beds supported distinct microbial communities with higher diversity and enrichment of nitrogen-cycling bacteria, highlighting the role of seagrass in structuring sediment microbiomes and nutrient cycling.
Seasonal Dynamics of Marine Bacterial Communities in Aquaculture Farms: The case of the Northern Ionian Coastal Ecosystem (Mediterranean Sea)
Researchers characterized seasonal bacterial community dynamics across three Greek aquaculture farms in the Mediterranean, finding lower microbial diversity at farm sites compared to controls, with season being the primary driver of community composition changes.
Seasonal and Spatial Dynamics of Fungal Diversity and Communities in the Intertidal Zones of Qingdao, China
Researchers examined seasonal and spatial dynamics of fungal communities in intertidal zones of Qingdao, China, using DNA metabarcoding. The study found that sediment fungal communities shifted with both season and location, while seawater communities changed only seasonally, and unexpectedly, the lowest fungal diversity was observed during summer at swimming beaches with heavy tourist activity.
Exploring the Microdiversity Within Marine Bacterial Taxa: Toward an Integrated Biogeography in the Southern Ocean
Researchers used advanced sequencing techniques to study the fine-scale diversity and geographic distribution of bacteria in the Southern Ocean. Understanding ocean microbial communities is relevant to microplastic research because plastics in the ocean host distinct microbial communities that can alter local ecology.
Bacterial Community Structure and Its Influencing Factors in Surface Sediments of the Nyang River in the Dry Season, China
Researchers analyzed bacterial community diversity in surface sediments of the Nyang River in Tibet using high-throughput sequencing, finding that climate warming and human activities along this plateau river have measurably shaped microbial composition and structure.
Impact of mariculture-derived microplastics on bacterial biofilm formation and their potential threat to mariculture: A case in situ study on the Sungo Bay, China
Scientists examined biofilm colonization on mariculture-derived microplastics (fishing nets, foams, floats) in Sanggou Bay, China over 21 days and found distinct microbial communities including potential fish pathogens and antibiotic resistance genes, raising concerns for mariculture safety.
Contrasting the diversity patterns and processes of microbial community assembly in water and sediment in Lake Wuchang, China
This study investigated how bacterial communities are distributed between water and sediment in Lake Wuchang, China, finding that different ecological processes drive community assembly in each habitat. Understanding these microbial patterns helps clarify ecosystem function in freshwater lakes.

Researchers characterized prokaryotic communities in sewer sediments across multifunctional, commercial, and residential urban areas using 16S rRNA amplicon sequencing, finding significant compositional differences linked to land use and nutrient levels. Network analysis revealed the residential area harbored the most complex and stable microbial network, while stochastic processes dominated community assembly across all zones.
Multi-omics-based approach reveals the effects of microplastics on microbial abundance and function of sediments in Shenzhen coastal waters
Researchers used a multi-omics approach combining metagenomics and metatranscriptomics to investigate how microplastic contamination affects microbial community abundance and functional gene expression in coastal sediments from eastern and western Shenzhen, China. They found microplastic concentrations of 119 items per kilogram in eastern sediments and 664 items per kilogram in western sediments, with higher contamination sites showing significant shifts in microbial community composition and altered expression of genes involved in carbon, nitrogen, and sulfur cycling.
Microplastic pollution and its relationship with the bacterial community in coastal sediments near Guangdong Province, South China
This study systematically characterized microplastic pollution in coastal sediments near Guangdong Province, China, and found that microplastic abundance was linked to changes in the local bacterial community.
