The natural resistance of plant cell walls to microbial and enzymatic deconstruction, known as biomass recalcitrance, is still not completely understood and is still largely responsible for the high cost of lignocellulose conversion. Several technologies have been developed in the past to allow the conversion process of lignocellulosic materials. However, research is still needed to answer some of the questions regarding the conversion and to make the process cost-competitive in today’s markets.
Research in Labbé’s lab focuses on the development of new roads to effectively fractionate biomass components (cellulose, hemicellulose, and lignin). The products of this research will be unpolluted building blocks that can be converted into fuels, products and chemicals. It will also help to answer some fundamental questions such as how can we reduce the recalcitrance of lignocellulosic biomass, what is the real structure of lignin, how can we extract lignin from plant tissues with minimum degradation with the overall aim of optimizing the utilization of cellulosic and phenolic plant constituents for fuels and chemicals?
Additionally, rapid and inexpensive methods that monitor the chemical composition of biomass samples are key elements to enable the commercialization of lignocellulosic biomass conversion to fuels and chemicals. The chemical composition of biomass feedstock varies as a function of many factors including plant genetics, growth environment, harvesting time, and storage. These needs motivate Labbé’s second research area: the development of high throughput technologies that can be employed at different levels (field, lab, biorefinery) to determine the quality and performance of biomass.
The overall goal of Labbé’s research program will directly help advance the mission and vision of the Center for Renewable Carbon, Agricultural Experiment Station, University of Tennessee.
