Hydrothermal liquefaction is a thermochemical technique for obtaining crude bio-oil from lignocellulosic biomass with moderate temperature and pressure. The crude bio-oil can then be upgraded to various biofuels and bioproducts. Hydrothermal liquefaction is amenable to use of biomass feedstocks that have high-moisture. The overall goal of this research is to demonstrate the effectiveness of white rot fungus (WRF) as a pretreatment option in the production of bio-oil from switchgrass through hydrothermal liquefaction. If WRF is an effective pretreatment, it could be a cost-effective option for commercialization, allowing hydrothermal liquefaction to be used on an industrial scale to produce high quality …

Development of biomass feedstocks with desirable traits for cost-effective conversion is one of the main focus areas in biofuels research. As suggested by techno-economic analyses, the success of a lignocellulose-based biorefinery largely relies on the utilization of lignin to generate value-added products, i.e. fuels and chemicals. The fate of lignin and its structural/compositional changes during pretreatment have received increasing attention; however, the effect of genetic modification on the fractionation, depolymerization and catalytic upgrading of lignin from genetically engineered plants is not well understood. This study aims to fractionate and characterize the lignin streams from a wild-type and two genetically engineered …
