ClearA preliminary study of the association between colonization of microorganism on microplastics and intestinal microbiota in shrimp under natural conditions
Microplastics were detected in shrimp pond sediment (5,129 ± 1,176 items/kg) and in Litopenaeus vannamei shrimp tissue (14.08 ± 5.70 items/g), with MP abundance positively correlated between sediments and shrimp, and the microbiome on plastic surfaces differing from the shrimps' intestinal microbiota.
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. Higher microplastic levels were associated with shifts in microbial diversity, suggesting plastic pollution can alter the microbial ecology of marine sediments.
The effects of environmental Microplastic on wharf roach (Ligia exotica): A Multi-Omics approach
Wild wharf roaches collected from a microplastic-contaminated South Korean shoreline had 50 times more plastic particles in their guts than roaches from a cleaner site, and the contaminated animals also carried elevated levels of brominated flame retardants leached from the polystyrene foam they had ingested. Gene expression analysis revealed that the contaminated roaches showed altered immune, metabolic, and stress-response pathways. Because wharf roaches are a key detritus-consuming species in coastal ecosystems, this study demonstrates that microplastic pollution can have cascading biological effects from the base of the food web.

Microplastic contamination and microbial colonization in coastal area of Busan City, Korea
Researchers investigated microplastic concentrations, characteristics, and associated microbial communities across six coastal sites in Busan, South Korea, finding average concentrations of 94 particles/m3 dominated by PE, PP, and PS polymers, and using 16S rRNA sequencing to demonstrate that MP-associated bacterial communities were distinct from surrounding seawater, enriched in Psychrobacter, Pseudomonas, and Flavobacterium.
Influence of Microplastics on the Growth and the Intestinal Microbiota Composition of Brine Shrimp
Researchers exposed brine shrimp to polyethylene and polystyrene microplastics and found that both types significantly reduced growth rates, with body length decreasing by 15-18%. The study also revealed that microplastic ingestion altered the gut microbiota composition, increasing microbial diversity and shifting the balance of key bacterial groups in the shrimp intestines.
Microplastic contamination alters microbial community in commercially important bivalves, Geloina expansa, Anadara cornea, and Meretrix meretrix from tropical waters
Researchers exposed three commercially important tropical bivalve species to polyethylene terephthalate microplastics for 10 days and found significant changes in their gut microbial communities. The effects varied between species and collection locations, with some bivalves showing increased harmful bacteria and reduced beneficial microbes. The study suggests that microplastic pollution can disrupt the gut health of seafood species that are important food sources in tropical regions.
Toxicological effects of microplastics in Litopenaeus vannamei as indicated by an integrated microbiome, proteomic and metabolomic approach
Shrimp (Litopenaeus vannamei) exposed to five microplastic types for 14 days showed gut microbiota shifts (increased Bacteroidetes and Proteobacteria, decreased Firmicutes) and altered haemolymph proteomes, with each MP type producing distinct immune pathway effects.
Exposure to nanoplastics disturbs the gut microbiome in the soil oligochaete Enchytraeus crypticus
Researchers fed the soil oligochaete Enchytraeus crypticus diets containing different concentrations of nano-polystyrene particles and found that exposure significantly altered the gut microbiome composition. The study suggests that nanoplastic ingestion can disturb the microbial communities in soil invertebrate digestive systems, which may have cascading effects on nutrient processing and organism health.
The effects of exposure to microplastics and pollutants on the arthropod microbiome
This thesis investigated how microplastics and other pollutants (pesticides, detergents, metals) affect the gut microbiome of freshwater invertebrates. Disruption of the host-microbiome relationship by microplastics could impair immune function and overall health in aquatic organisms that form important parts of the food web.
Changes in the microbiome and associated host tissue structure in the blue mussel (Mytilus edulis) following exposure to polystyrene microparticles
Blue mussels (Mytilus edulis) exposed to polystyrene microplastics at concentrations found in coastal waters showed reduced microbiome diversity in digestive gland and gill tissues at high exposure levels, along with altered host tissue structure. The co-disruption of the microbiome and host tissues suggests that MP exposure can degrade the symbiotic relationships that support mussel health.
Microbiome: A forgotten target of environmental micro(nano)plastics?
This review examines how micro- and nanoplastics affect the microbiome of various organisms, an area that has received less attention than other toxicological endpoints. Researchers found that most studies focused on polystyrene particles and that exposure consistently disrupted microbiome composition, triggered immune responses, and altered enzyme activity across organisms including crustaceans, fish, and mammals. The study highlights the microbiome as an important but often overlooked target of microplastic pollution.

Abundance and characterization of microplastics in amphipods from the Japanese coastal environment
Researchers found high levels of microplastic ingestion in coastal amphipods from Japan, with up to 76 particles per individual and 83% of particles smaller than 90 µm, predominantly polyethylene, raising concerns about microplastic transfer through coastal food webs.
Analysis of 16S rRNA amplicon data illuminates the major role of environment in determining the marine plastisphere microbial communities
By reanalyzing publicly available microbiome data from marine microplastics collected at multiple ocean locations, this study found that the surrounding water environment shapes the community of microbes living on plastic surfaces (the plastisphere) more strongly than the type of plastic polymer does. While both location and polymer type matter, once environmental differences were accounted for, polymer type alone had no statistically significant effect on microbial diversity. This is important because microplastics can carry and transport harmful microbes across vast ocean distances, and understanding what controls those communities helps assess the ecological risk.
