Agricultural beneficial microbes accelerate soil degradation of poly(butylene adipate-<i>co</i>-terephthalate) (PBAT) films.

ABSTRACT: Three common agricultural beneficial microbes, Trichoderma harzianum, Bacillus cereus, and Pseudomonas fluorescens, were utilized as effective agents in enhancing the degradation of poly(butylene adipate-co-terephthalate) (PBAT) within a soil environment. All of microbes accelerated the degradation of PBAT. Under specific conditions(Tri15), the degradation rate of PBAT films at 360 days can achieve over 70%. Scanning electron microscopy (SEM) images show that the surface of PBAT films cracks after 360 days of exposure to these three specific microbes because of the degradation of the PBAT. Gel permeation chromatography (GPC) analysis reveals that in the presence of these microbes the PBAT undergoes progressive molar-mass reduction. The 16S rRNA sequencing analys
