ClearMicroplastics in the diet of Hermetia illucens: Implications for development and midgut bacterial and fungal microbiota
Researchers fed black soldier fly larvae diets containing PVC microplastics at various concentrations and found the insects could tolerate even high levels (20% of diet) without significant increases in death rates. The larvae ingested and reduced the size of the plastic particles, and while their overall gut microbial diversity remained stable, certain bacterial and fungal populations shifted. This suggests black soldier flies could potentially help process plastic waste, though the safety of using these insects as animal feed after plastic exposure needs further study.
Black Soldier Fly (Hermetia illucens) Microbiome and Microbe Interactions: A Scoping Review
This scoping review examined all peer-reviewed literature on the microbiome of black soldier fly larvae, which are farmed worldwide to convert organic waste into biomaterials. Researchers found no evidence of a universally conserved core microbiome, as diet strongly shaped gut bacterial communities, though certain genera appeared frequently across studies regardless of diet. The review highlights the potential of gut-associated microbes as probiotics to improve larval fitness and bioconversion rates.
Modulation of Atlantic salmon (Salmo salar) gut microbiota composition and predicted metabolic capacity by feeding diets with processed black soldier fly (Hermetia illucens) larvae meals and fractions
Researchers fed Atlantic salmon different preparations of black soldier fly larvae — whole, de-fatted, or with exoskeletons removed — and found that full-fat larvae meal most favorably altered the gut bacteria in young salmon. The findings suggest that how insect feed is processed matters for fish gut health, which has implications for sustainable aquaculture practices.
The Role of Danio rerio in Understanding Pollutant-Induced Gut Microbiome Dysbiosis in Aquatic Ecosystems
This review examines how freshwater pollutants—including pesticides, heavy metals, antibiotics, dyes, and microplastics—disrupt gut microbiome composition in zebrafish and other aquatic animals. It highlights the zebrafish model as a key tool for understanding pollutant-driven microbiome dysbiosis and its metabolic consequences.
Examining the potential of plastic-fed black soldier fly larvae (Hermetia illucens) as "bioincubators" of plastic-degrading bacteria.
Researchers examined whether black soldier fly larvae (Hermetia illucens) fed on plastic waste can serve as 'bioincubators' for plastic-degrading bacteria, investigating how gut microbiota shifts in response to plastic-containing diets and whether these bacteria retain degradation activity.
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.
Effects of polystyrene microplastics on the composition of the microbiome and metabolism in larval zebrafish
Researchers exposed larval zebrafish to two sizes of polystyrene microplastics and found significant changes in gut microbiome composition and metabolic activity. The microplastics altered the abundance and diversity of gut bacteria and disrupted metabolic pathways important for development. The study suggests that early-life exposure to microplastics could have meaningful biological consequences by reshaping the gut environment of developing organisms.
Polystyrene microplastics induce gut microbiome and metabolome changes in Javanese medaka fish (Oryzias javanicus Bleeker, 1854)
Researchers found that polystyrene microplastic exposure altered gut microbiome composition and metabolic profiles in Javanese medaka fish, with effects on amino acid and lipid metabolism pathways suggesting microplastics can disrupt gut health in aquatic organisms.
Acute exposure to microplastics induces metabolic disturbances and gut dysbiosis in adult zebrafish (Danio rerio)
Researchers exposed adult zebrafish to polyethylene and polyester microplastics and used untargeted metabolomics and gut microbiome analysis to assess the effects. The study found that acute microplastic exposure caused significant metabolic disturbances and gut dysbiosis, altering key metabolites involved in lipid and amino acid metabolism.
Plastics shape the black soldier fly larvae gut microbiome and select for biodegrading functions
Researchers found that black soldier fly larvae can adapt their gut microbiome to digest a wide range of plastics, shifting their microbial communities to favor biodegrading functions. This suggests the insects could serve as living incubators for discovering new plastic-breaking enzymes for industrial cleanup applications.
A fishy gut feeling – current knowledge on gut microbiota in teleosts
This review summarizes what scientists know about the community of bacteria living in fish guts and how diet, environmental conditions, and pollutants shape that community. Microplastics and other pollutants can disrupt the gut microbiome in fish, harming their immune function and overall health. Since fish are a major food source for humans, understanding these effects matters for food safety.
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.
Effects of MP Polyethylene Microparticles on Microbiome and Inflammatory Response of Larval Zebrafish
Zebrafish larvae exposed to polyethylene microplastics for up to 10 days showed no broad metabolic disturbances or inflammatory changes, but oxidative stress markers increased at 15 days and the gut microbiome was disrupted, with higher levels of bacteria linked to intestinal disease. The findings suggest microplastics alter the microbial environment of fish guts without triggering obvious inflammation.
Microplastics affected black soldier fly (Hermetiaillucens) pupation and short chain fatty acids
Researchers exposed black soldier fly (Hermetia illucens) larvae to polypropylene microplastics and found that MP exposure delayed pupation, altered larval development, and shifted gut short-chain fatty acid profiles, suggesting that microplastics disrupt both development and gut microbiome function in this widely used bioconversion insect.
Within-species variation in the gut microbiome of medaka (Oryzias latipes) is driven by the interaction of light intensity and genetic background
This paper is not about microplastics; it studies how light intensity and evolutionary history (lineages selected under fishing-like vs. natural mortality) interact to shape gut microbiome diversity and composition in medaka fish.
The Role of Organic Waste Feed Combination on Growth Rate and Nutrient Content of Hermetia Illucens Larvae
This study examines how different organic waste feed combinations affect the growth and nutritional content of black soldier fly (Hermetia illucens) larvae. While not directly about microplastics, these larvae are also studied for their ability to biodegrade plastic waste.
Chronic Exposure of Adult Zebrafish to Polyethylene and Polyester-based Microplastics: Metabolomic and Gut Microbiome Alterations Reflecting Dysbiosis and Resilience
Researchers exposed adult zebrafish to polyethylene and polyester microplastics at environmentally relevant concentrations and found significant disruptions to metabolic pathways and gut microbiome composition. Polyethylene primarily affected cell membrane compounds and inflammation-related metabolites, while polyester altered lipid metabolism and gut bacterial interactions. The study reveals that chronic microplastic exposure can cause subtle but meaningful shifts in fish metabolism and gut health, even at low concentrations.
