The biodegradation of polypropylene (PP), a highly persistent nonhydrolyzable polymer, by Tenebrio molitor has been confirmed using commercial PP microplastics (MPs) (Mn 26.59 and Mw 187.12 kDa). This confirmation was based on the reduction mass, change in molecular weight (MW), positive Δδ13C residual PP. A MW-dependent mechanism investigated five high-purity MPs, classified into low (0.83 6.20 kDa), medium (50.40 108.0 high (575.0 kDa) MW categories to access impact depolymerization pattern associated gene expression gut bacteria larval host. larvae can depolymerize/biodegrade polymers with although consumption rate losses increased, survival rates declined increasing MW. is similar observations polystyrene (PS) polyethylene (PE), i.e., both Mn decreased after being fed PP, while and/or increased fed. microbiota exhibited specific associations, such as Kluyvera sp.

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.

The insect Tenebrio molitor exhibits ultrafast efficiency in biodegrading polystyrene (PS). However, the generation and fate of nanoplastics (NPs) intestine during plastic biodegradation remain unknown. In this study, we investigated PS microplastics (MPs) mediated by T. larvae over a 4-week period confirmed analyzing Δδ13C before after biotreatment (−28.37‰ versus −24.88‰) as an effective tool. ·OH radicals, primarily contributed gut microbiota, H2O2, produced host, both increased MP digestion. size distribution residual particles excrements fluctuated within micrometer ranges. NPs were detected but not excrements. At end Weeks 1, 2, 3, 4, concentrations tissues 3.778, 2.505, 2.087, 2.853 ng/lava, respectively, while glands quantified at 0.636, 0.284, 0.113 ng/lava eventually fell below detection limit. remained limit 5 6. This indicates that initially, generated entered glands, then declined gradually disappeared or possibly biodegraded Week associated with elevated plastic-degrading capacities larvae. Our findings unveil rapid synergistic larval host well NPs, providing new insights into risks invertebrate-mediated biodegradation.
