报告摘要:

Our generation faces daunting energy and environmental challenges, ranging from greenhouse gas emissionsto the accumulation of persistent contaminants. The solutions to those challenges cannot rely on chemicasolutions alone but require integrated approaches with high energy efficiency yet low negative environmentaimpacts. To overcome these challenges, we have constructed various chem-bio and material-bio hybrid systemsand processes to achieve sustainable commodity product manufacturing from CO2 and efficient bioremediationof persistent organic pollutants (POPs) like PFAS. First, we have integrated the catalyst and microbial designsto build highly efficient Chem-Bio synthetic pathways, producing electrobioplastics and electrobiodiesel fromCO2 with more than four-fold higher efficiency than natural photosynthesis. Second, we employed a reverseengineering principle and designed a biomimicking sorbent derived from lignocellulosic biomass, achieving arecord level of PFAS absorption. Since the sorbent is lignocelulosic biomass-based, it can support the growth ofbioremediation fungus and induce redox enzyme expression. The material-bio system creates an integratedtreatment train, where the biomimicking sorbent absorbs PFAS and presents to fungus for bioremediation.avoiding secondary hazards and substantially improving bioremediation capacity. Furthermore, based on ourunderstanding of biomass structure, we have designed a lignin nanoparticle-doped catalyst to achieve efficienPOP degradation and bacterial removal under ambient conditions. Finally, we have leveraged the chemometricsapproach to achieve efficient community sampling and risk management for safeguarding public health throuarreducing environmental chemical exposure in vulnerable communities.
