Abstract
The use of poly (butylene adipate-co-terephthalate) (PBAT) has increased widely but PBAT-degrading bacteria have rarely been studied. During this study, we used farm soil (Shaanxi (yuan Jia cun)) to isolate and identify PBAT-degrading bacteria (Bacillus strains). We then accessed the effect of growth factors on PBAT degradation as well as the lipase activity of PBAT-degrading bacteria. The serial dilution method was used to isolate the PBAT-degrading microbes from the farm soil of Xinjiang. Microbial colonies were spread and streaked many times to get pure colonies. Xin-A and Xin-B were gram-positive bacteria. Lipase production of these strains was studied using para nitrophenyl palmitate as a substrate which showed that both bacteria were lipase producing and the lipase production of Xin-B (14 U/mL) was superior to Xin-A (11.7 U/mL) degrading almost 13.7% PBAT in 14 days. These results provide technical support for the highly efficient degradation of PBAT in the environment.
