Biomolecular synthesis of sustainable materials and chemicals
Plants sustainably synthesize the most abundant and among the most diverse materials on Earth. By applying recent advances in life science technology (e.g. genomics, high-throughput instrumentation for biochemical and biophysical characterizations, bioinformatics), we as a community are learning how to better harness renewable plant resources to thereby enjoy better and more sustainable lives. At the same time, the global market for high-value biochemical and bioplastics from forest and agricultural sources is rapidly increasing, which presents new opportunities for forest and agricultural sectors that are important to Canada’s economy and support small communities across our country.
Accordingly, the aim of our research program is to harness recent advances in life science technology to discover and develop enzymes and non-catalytic proteins that can be used to sustainably synthesize high-value chemicals and polymers from renewable plant resources. Given the complexity and highly functionalized chemistry of plant macromolecules (e.g. hemicellulose and lignin), the reactive specificity of many enzymes is particularly valuable in the development of new bio-based materials that have tailored and reproducible performance. In particular, our biological approach to developing high-value products from plants benefits from two key advantages of many bioprocesses, 1) catalytic specificity that is critical to the bioactivity of derivatized biochemicals and modification of heterogeneous plant polymers, and 2) comparatively mild reaction requirements that retain valuable properties of starting plant materials (e.g. degree of polymerization).
