Abstract Insects damaging and penetrating plastic packaged materials has been reported since the 1950s. Radical innovation breakthroughs of biodegradation have initiated discovery plastics by Tenebrio molitor larvae in 2015 followed Galleria mellonella 2017. Here we review updated studies on insect-mediated plastics. Plastic insect larvae, mainly some species darkling beetles (Tenebrionidae) pyralid moths (Pyralidae) is currently a highly active potentially transformative area research. Over past eight years, publications increased explosively, including discoveries ability different to biodegrade plastics, performance, contribution host microbiomes, impacts polymer types their physic-chemical properties, responsible enzymes secreted gut microbes. To date, almost all major polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), terephthalate (PET), polyurethane (PUR), polystyrene (PS) can be biodegraded T. ten other representing Tenebrionidae Pyralidae families. The processes are symbiotic reactions or performed synergistic efforts both gut-microbes rapidly depolymerize with hourly half-lives. digestive ezymens bioreagents screted insects play an essential role plasatic certain New research itself, transcriptomes, proteomes metabolomes evaluated mechanisms insects.

The Development of Yellow Mealworm (Tenebrio molitor) as a Cheap and Simple Model to Evaluate Acute Toxicity, Locomotor Activity Changes, and Metabolite Profile Alterations Induced by Nanoplastics of Different Sizes

Journal of Applied Toxicology, Год журнала: 2025, Номер unknown

ABSTRACT Due to the wide uses of plastic products, nanoplastics are ubiquitous contaminants in environment. Hence, extensive studies used various models evaluate toxicity nanoplastics. In present study, we developed yellow mealworm ( Tenebrio molitor ) as an alternative model investigate acute Our results showed that microinjection with 500 mg/kg significantly increased death rate mealworms after 24 or 48 h, 100 nm particles being more effective compared 20 ones. Meanwhile, dose‐dependent increase was observed injection 2–200 Exposure 2 but not also led hyperactivity mealworms. Both types altered metabolite profiles, up‐regulated and down‐regulated 9 12 metabolites, whereas 16 25 respectively. Enrichment analysis revealed affected alpha‐linolenic acid metabolism (ko00592) purine (ko00230). For metabolites belonging these pathways, stearidonic guanine. Combined, size‐dependent effects on toxicity, profile changes These indicated potential a cheap simple

Enhancing Plastic Decomposition in Mealworms (Tenebrio molitor): The Role of Nutritional Amino Acids and Water

Advanced Energy and Sustainability Research, Год журнала: 2025, Номер unknown

Опубликована: Фев. 23, 2025

Certain insects, such as mealworms ( Tenebrio molitor ), have shown the ability to effectively biodecompose plastic waste under environmentally benign conditions. However, sustaining this biodecomposition within insect populations presents challenges, high mortality rates and relatively slow decomposition limit viability of large‐scale recycling. To enhance process, protein‐rich nutritional additives are usually necessary. Despite this, there has been little guidance on selecting suitable nutrients for plastic‐eating insects like mealworms. In systematic investigation, aqueous solutions representative nonessential amino acids (NEAAs) essential (EAAs) used compared polystyrene by The study demonstrates that essentiality abundance in significantly impact rate biodecomposition. High‐abundance EAAs, phenylalanine (Phe) valine (Val), provide most notable enhancements, while low‐abundance NEAAs, cysteine (Cys), do not rate. results also indicate both water individual free acid reduce cannibalistic behavior among mealworms, enhancing their value. These findings a more rational basis cofeeds improve process.

The effects of alumina and polystyrene nanoparticles on global DNA methylation, antimicrobial peptides and intergenerational inheritance of Galleria mellonella

Drug and Chemical Toxicology, Год журнала: 2025, Номер unknown, С. 1 - 14

Опубликована: Март 31, 2025

The epigenetic and immunological effects of nanoparticles (NPs), which have started to be described as nano-pollutants today, are great interest in living organisms. Particularly alumina (Al) polystyrene (PS) among the most produced NPs. Galleria mellonella larvae, an ideal model for multi-generational these NPs on global DNA methylation immune system, were used experiments. Al-NPs bought, PS-NPs by single emulsion solvent evaporation method. Al administered larvae at different concentrations changing only water content diet. Global levels first second generations determined HPLC. expression β-actin, transferrin, galiomycin, p38 MAPK genes constitute antimicrobial peptides, one humoral responses, RT-qPCR two generations. data obtained revealed that increased methylation, partially suppressed responses. Furthermore, changes genomic immune-related gene induced generation found inherited next generation. Considering importance multigenerational our study results contribute literature reveal such studies.

Polyethylene (PE) is the second most abundant plastic worldwide due to its broad application in manufacturing disposable materials such as bags and bottles. Since it highly resistant natural biodegradation, can accumulate landfills, causing various ecological toxicological consequences. Even though microbial degradation of PE has been extensively investigated, complete biodegradation yet be achieved, comparisons experiment findings are not practical. This may wide variety substances used, a culture conditions, many published still need key chemistry materials, well basic biochemistry microbiology. review highlights for standardization studies defining biochemical terms. It aims identify deficiencies challenges experiments, enhancing future research scientific technological advancement. provides biochemically based definition summarizes microorganisms responsible biodegradation.
