The biodegradation method includes the following steps: step (1), cutting an appropriate quantity of plastic products into small pieces; step (2), placing the plastic products in a ball mill tank and milling the plastic products in vacuum in a ball mill; step (3), weighing and dispersing the milled plastic sample with water to prepare a dispersion with a concentration; step (4), mixing the micro-nano plastic dispersion with a metabolic enzyme solution, and placing the mixed solution in a vortex oscillator for mixing well; and step (5), incubating the mixed solution in a waterproof incubator. The present invention provides for the first time a method for biodegradation and metabolism of micro-nano plastics under mild conditions and under the induction of a metabolic enzyme, namely, glutathione S-transferase."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Metabolic enzyme-induced micro-nano plastic particle biodegradation method and product analysis method therefor","description":"A metabolic enzyme-induced micro-nano plastic particle biodegradation method and a product analysis method therefor are disclosed.
