The Effects of Probiotics on the Recovery of Growth, Digestive, Antioxidant, Immune Functions, and Gut Microbiota of Chinese Hooksnout Carp (Opsariichthys bidens) Under Microplastic Stress
Researchers exposed juvenile Chinese hooksnout carp to polystyrene microplastics for seven days, then administered Bacillus coagulans probiotics at three doses for 56 days and found that medium and high probiotic doses significantly improved growth, digestive enzyme activity, antioxidant function, and gut microbiota recovery.
Investigation of microplastic accumulation in Rastrelliger kanagurta fish gut and microplastic degradation behaviour of existing gut bacteria Pseudomonas sp.
Researchers found microplastic accumulation in the gut of Indian mackerel fish and identified a Pseudomonas species from the gut bacteria capable of degrading nylon microplastics, suggesting a potential probiotic role in microplastic breakdown.
Connection between the Gut Microbiota of Largemouth Bass (Micropterus salmoides) and Microbiota of the aquaponics system Environment
Researchers investigated the relationship between gut microbiota composition in largemouth bass and the presence of microplastics in their digestive tracts, finding that microplastic-exposed fish showed distinct microbial community profiles. Certain bacterial taxa associated with plastic degradation were enriched in fish with higher microplastic burdens, suggesting gut microbiota adapt to plastic ingestion.
Characteristics of microplastic pollution in golden pompano (Trachinotus ovatus) aquaculture areas and the relationship between colonized-microbiota on microplastics and intestinal microflora
Researchers found that microplastics in golden pompano aquaculture areas colonize with distinct microbial communities that overlap with the fish's gut microbiota, increasing Proteobacteria and decreasing Firmicutes in the intestinal flora of fish living in more contaminated estuarine settings.
The Characteristics of Intestinal Bacterial Community in Three Omnivorous Fishes and Their Interaction with Microbiota from Habitats
This study examined the gut bacterial communities of three omnivorous fish species in artificial fishery habitats, comparing them to bacteria in the surrounding water and sediment. Fish gut microbiomes partially reflected the environmental microbiota, suggesting habitat quality affects fish gut health. This is relevant to microplastics because microplastics alter both aquatic microbial communities and fish gut microbiomes.
Chironomus riparius Larval Gut Bacteriobiota and Its Potential in Microplastic Degradation
Researchers characterized the gut bacteria of Chironomus riparius midge larvae and identified strains with plastic-degrading enzyme potential, suggesting that the gut microbiome of sediment-dwelling invertebrates may play a role in breaking down ingested microplastics in freshwater ecosystems.
Plastics in our water: Fish microbiomes at risk?
This review examined how microplastics and leached plasticizers affect the gut microbiomes of freshwater and marine fish, summarizing evidence for dysbiosis and reduced microbial diversity and discussing potential consequences for fish immunity, metabolism, and environmental fitness.
Microplastics Change the Food Utilization of Filter-Feeding Fish via Gut Microbiota
Researchers found that microplastic exposure changed the food utilization patterns of filter-feeding silver carp by altering their gut microbiota. After exposure, the fish shifted from primarily consuming phytoplankton to greater utilization of zooplankton, driven by microplastic-induced changes in gut bacterial communities that affected digestive enzyme gene expression, suggesting microplastics can disrupt aquatic food web dynamics.
The characteristics of the novel bacterial strain Pseudomonas mendocina isolatedfrom freshwater aquaculture farm
Researchers characterised a novel Pseudomonas mendocina bacterial strain isolated from a freshwater aquaculture farm, examining its plastic-biodegrading properties and evaluating its potential to address plastic contamination affecting water quality and fish product safety.
Polystyrene microplastics interaction and influence on the growth kinetics and metabolism of tilapia gut probiotic Bacillus tropicus ACS1
Polystyrene microplastics were found to alter the gut microbiome of tilapia, disrupting the growth kinetics and metabolism of probiotic bacteria, with potential implications for fish health and aquaculture productivity.
The effect of planktivorous fish (juvenile Perca fluviatilis) on the taxonomic diversity of microplastic particles-colonized bacterial community
Researchers tested whether the presence of perch (a common freshwater fish) affects the bacterial communities colonizing microplastic particles in water. Fish exudates — waste products released into the water — significantly increased the abundance and diversity of bacteria growing on both polyethylene and polystyrene surfaces, which could eventually accelerate microbial degradation of the plastics. This has implications for understanding the long-term fate of microplastics in natural lake and river environments where fish and plastic debris coexist.
Histomorphological Changes in Fish Gut in Response to Prebiotics and Probiotics Treatment to Improve Their Health Status: A Review
This review summarizes how prebiotics and probiotics, beneficial supplements added to fish feed, can improve gut health and disease resistance in farmed fish. A healthy gut microbiome is critical for nutrient absorption and immune defense in fish. While not directly about microplastics, the research is relevant because microplastics are known to disrupt gut bacteria in aquatic organisms, and probiotics may help counteract some of those effects.
Ingested Microplastics Can Act as Microbial Vectors of Ichthyofauna
Nylon strips ingested and excreted by wild fish were found to harbor adherent microbiota including potential pathogens, demonstrating that microplastics can vector microorganisms through fish gut passage and into aquatic environments.
