Polyurethane enzymatic degradation
WebMar 24, 2024 · In contrast with polymers constructed via carbon-carbon bonds, PBAT was first considered as a compostable biopolymer because polyesters are more susceptible to enzymatic degradation, such as by esterases 8. However, albeit easier to be fragmented in the environment, the natural degradation rate of PBAT is quite slow. WebThe physicochemical indices of water quality parameters, the real-time quantification of pollutant concentrations, and the rhizosphere enzyme activity and microbial community were detected using a synthetic wastewater hydroponic experiment to investigate: 1) the difference between specific and non-specific degradation of PAHs by different ROA …
