Abstract

The invention belongs to the technical field of plastic degradation, and discloses a Tenebrio molitor and a method for degrading plastic by using Tenebrio molitor. The mealworm feed attractant includes glutamic acid or glutamate, and sugars. Through the combined use of glutamic acid or glutamate and saccharides, the present invention can induce Tenebrio molitor to eat plastic, especially polystyrene, so that the daily rate of plastic degradation of Tenebrio molitor and its intestinal microorganisms is increased by about 125%. %‑224%. The method for degrading plastic by using Tenebrio molitor provided by the invention has the advantages of simple operation, easy preparation of raw materials, high plastic degradation efficiency, and can be suitable for large-scale degradation application of plastic.

Description

technical field [0001] The invention belongs to the technical field of plastic degradation, and in particular relates to a Tenebrio molitor and a method for degrading plastic by using Tenebrio molitor. Background technique [0002] Plastic is a very refractory material, such as polystyrene, which takes about 10,000 years to degrade naturally. Even if it can be degraded in nature, it will cause microplastic pollution, impact the natural ecology and food chain, and will also affect human drinking water resources and food in the long run. And burning plastic will also release many harmful substances. For example, burning polystyrene will produce about 50 kinds of harmful gases, such as styrene, benzene, carbon monoxide, methane, toluene and ethylene. At present, it is found that the use of biodegradable plastics does not detect harmful substances during the degradation process, which is a very environmentally friendly degradation method. However, using biodegradation, its eff...
