讲座内容：

To convert lignocellulosic biomass to fuels and chemicals, two platforms are commonly used: (1) Thermochemical platform – Biomass is thermally processed to pyrolysis oil or synthesis gas, which is subsequently catalytically transformed into chemicals and fuels, and (2) sugar platform – Enzymes are added to biomass to produce sugars that are fermented to industrial chemicals or fuels. The thermochemical-biological conversion process is a hybrid approach that employs both thermochemical and biological processes to transform biomass to chemicals and fuels. Depending on the thermochemical process used, the hybrid platform can either be a fast pyrolysis of biomass into pyrolytic substrates followed by microbial fermentation, or a gasification of biomass into synthesis gas (syngas) followed by syngas fermentation.

Microalgae have been widely studied to remove nutrients from wastewater but the commercial implementation of open pond as a treatment system has not happened due to high operation cost and the large footprint of these systems. His research group developed a unique culture system so called revolving algal biofilm (RAB) for solving the above problems. The RAB system has been used for municipal wastewater and food industrial effluent with superior efficiency of removing nitrogen, phosphorus and special chemicals.
