Abstract

The invention provides a strain of Stenotrophomonas that efficiently degrades polybutylene terephthalate / adipate and the application thereof. The present invention isolates and screens a PBAT-degrading bacterium that can secrete lipase, Stenotrophomonas sp.strain YCJ1, from the soil of Yanxia Town, Liquan County, Shaanxi Province, and names it Stenotrophomonas sp. Species Collection and Management Center, the deposit number is CGMCC 18059. The advantage of the present invention is that the bacterium can secrete lipase and efficiently degrade PBAT, and the bacterium has a better degradation effect under alkaline conditions, and the Stenotrophomonas and its lipase can be used as enzyme preparations and biological agents It has a good application value when applied to the environmental remediation of PBAT and PBAT-based biodegradable materials in alkaline environment.

Description

technical field

[0001] The invention belongs to the technical field of PBAT degradation, and in particular relates to a strain of Stenotrophomonas sp.strain YCJ1 that efficiently degrades PBAT. Background technique

[0002] Polybutylene terephthalate / adipate (PBAT) is an aliphatic biodegradable material, because it has good mechanical properties, thermoplasticity and performance of traditional plastics, and at the same time, PBAT can be destroyed by microorganisms in the environment. It is degraded by lipase and has good biodegradability, which makes PBAT widely used in agriculture, food and packaging industries. However, current studies have found that the degree of degradation of PBAT is closely related to the physical and chemical properties of the environment, such as pH, temperature, and humidity. This is reflected in the fact that the degradation rate of PBAT in the northwest region is far lower than that in the southwest region. Moreover, the types and quantities of m...
