Enzymatic hydrolysis of cellulose by microorganisms is a key
step in the global carbon cycle. Despite its abundance only a
small percentage of microorganisms can degrade cellulose,
probably because it is present in recalcitrant cell walls. There
are at least five distinct mechanisms used by different
microorganisms to degrade cellulose all of which involve
cellulases. Cellulolytic organisms and cellulases are extremely

ABSTRACT Soil microbial diversity represents the largest global reservoir of novel microorganisms and enzymes. In this study, we
coupled functional metagenomics and DNA stable-isotope probing (DNA-SIP) using multiple plant-derived carbon substrates
and diverse soils to characterize active soil bacterial communities and their glycoside hydrolase genes, which have value for industrial applications. We incubated samples from three disparate Canadian soils (tundra, temperate rainforest, and agricultural)

I am a Ph.D. student in the Interdepartmental Microbiology program. My research focuses on determining the key microbial organisms involved in C cycling, particularly cellulose degradation. I use a combination of field experiments, to determine the impact of plant/soil interactions on microbial cellulose degradation, and lab incubations with fluorescently labeled cellulose nanocrystals to directly determine the key microbes involved in C cycling.
