ClearComparative metagenomic analysis from Sundarbans ecosystems advances our understanding of microbial communities and their functional roles
Researchers used metagenome analysis — reading all genetic material from environmental samples — to map the microbial communities in the world's largest mangrove forest, the Sundarbans, finding a rich diversity of bacteria including methane-processors, nitrogen-cyclers, and pollution-remediating species absent from nearby non-mangrove soils. The study provides the first comprehensive microbial inventory of this critical ecosystem and highlights its potential for bioremediation of environmental pollutants.
Peer Review #2 of "Large-scale differences in diversity and functional adaptations of prokaryotic communities from conserved and anthropogenically impacted mangrove sediments in a tropical estuary (v0.2)"
This is a peer review comment on a study examining microbial communities in mangrove sediments affected by human activities. It is a peer review document, not a primary research paper, and is not directly focused on microplastics.
Diversity of Indigenous Bacteria from Mangrove Sediments in the Waters of Ambon Bay, Maluku
Researchers compared culture-based and culture-independent methods to characterise indigenous bacterial diversity in polluted versus natural mangrove sediments in Ambon Bay, Maluku, Indonesia, while also assessing physicochemical influences on community composition. They identified 33 isolates including Acinetobacter haemolyticus and Exiguobacterium acetylicum as dominant species across both habitat types.
A review on microplastic pollution in the mangrove wetlands and microbial strategies for its remediation
Researchers reviewed the growing problem of microplastic pollution in mangrove wetland ecosystems and its effects on the biological communities that depend on these habitats. They found that microplastic exposure can substantially alter the microbial communities critical to nutrient cycling in mangrove environments. The review also explores microbial bioremediation strategies as a sustainable approach to addressing plastic pollution in these threatened coastal ecosystems.

Finding microbial composition and biological processes as predictive signature to access the ongoing status of mangrove preservation
Using DNA sequencing, researchers mapped the microbial communities in mangrove soils of a large Brazilian bay, comparing pristine and polluted areas near a petroleum refinery. Polluted mangroves showed increased populations of bacteria adapted to breaking down hydrocarbons, while beneficial organisms like diatoms declined. While focused on oil pollution, the findings are relevant to microplastics research because mangroves act as filters for coastal pollution, and degraded mangrove ecosystems are less effective at trapping microplastics before they reach the ocean.
Baja California Sur mangrove deep peat microbial communities cycle nitrogen but do not affect old carbon pool
Researchers examined how microbial communities in deep mangrove peat cycle nitrogen without significantly decomposing the ancient carbon stored there, which helps mangroves remain long-term carbon sinks. Microbial community composition changed with peat age but nitrogen cycling activity was maintained. These findings support the view that protecting mangroves is important for climate change mitigation through carbon sequestration.
16S rRNA gene amplicon-based metagenomic analysis of bacterial communities in the rhizospheres of selected mangrove species from Mida Creek and Gazi Bay, Kenya
This metagenomic study characterized rhizosphere bacterial communities of four mangrove tree species in Kenya, finding species-specific differences in microbial diversity and community structure that reflect the distinct root chemistry and sediment conditions of each mangrove host.
Screening for Polypropylene Degradation Potential of Bacteria Isolated from Mangrove Ecosystems in Peninsular Malaysia
Two bacterial species isolated from mangrove sediments in Malaysia were found to partially degrade polypropylene plastic, as measured by weight loss and surface changes after incubation. Mangrove-associated bacteria capable of degrading plastics could have potential applications in biological plastic remediation.
Engineering the mangrove soil microbiome for selection of polyethylene terephthalate-transforming bacterial consortia.
Researchers engineered enrichment cultures from mangrove soil to select bacterial consortia capable of transforming polyethylene terephthalate (PET), finding via metagenome-assembled genomes that PET catabolism was distributed across multiple taxa harbouring putative novel PET-active hydrolases. They also described a novel species, Mangrovimarina plasticivorans, as a key consortium member containing genes for PET monomer metabolism.

Colonization characteristics and dynamic transition of archaea communities on polyethylene and polypropylene microplastics in the sediments of mangrove ecosystems
Researchers found that microplastics in mangrove sediments host distinct communities of archaea (ancient microorganisms) that differ from those in surrounding sediments, with some species linked to increased methane production. The microbial communities on microplastic surfaces shifted over time and showed increased potential for methane emissions and changes in nitrogen cycling. This suggests that microplastic pollution in coastal wetlands could amplify greenhouse gas production and disrupt nutrient cycles that support these critical ecosystems.

This study investigated whether bacteria isolated from mangrove sediments in Malaysia could degrade common microplastics under laboratory conditions, finding that bacterial consortia could break down polyethylene and polypropylene over time. The research suggests that mangrove microbial communities may harbor plastic-degrading bacteria relevant to natural bioremediation.

A review of antibiotic accumulation, degradation and ecological risk in typical mangrove ecosystems
This bibliometric and meta-analysis review synthesizes research on antibiotic accumulation and degradation in mangrove ecosystems, finding that sediment properties drive antibiotic buildup while specific bacteria mediate biodegradation — a balance further disrupted by co-contaminants such as microplastics and heavy metals. The review warns that antibiotic contamination in mangroves promotes the spread of antibiotic resistance genes and disrupts essential ecosystem functions like carbon and nitrogen cycling.
Microplastics and heavy metals reshape mangrove rhizosphere microbiomes and compromise carbon fixation potential
Researchers investigated how microplastics and heavy metals together affect the microbial communities around mangrove tree roots.

The study highlights that microplastic-metal co-contamination poses a compounding threat to mangrove ecosystems, which play an important role in coastal carbon storage.
