Biomass pre-treatment and production of intermediates (part 1)
Comparative Characterization of Two Similar Anaerobic Fungal Acetyl Xylan Esterases Upregulated on Lignocellulose
Short Introductive summary
Anaerobic Fungi (Neocallimastigomycota) are ubiquitous in the digestive tracts of herbivores, where they aid the animal in digesting plant biomass. Apart from the mechanical degradation of plant biomass via their filamentous structures, anaerobic fungi have a vast array of carbohydrate active enzymes at their disposal. Most of these enzymes are not yet characterized, making these fungi a potential source of novel, more efficient enzymes. We investigated two similar acetyl xylan esterases from Neocallimastix californiae, both upregulated in the presence of lignocellulose. With this comparative characterization, we aimed to gain insights into the effects of sequence variations on function in the vast enzyme arsenal of anaerobic gut fungi.

Presenter's biography
After finishing my master's thesis on biological methanation, I became a PhD student in the research group Environmental Biotechnology and Bioenergy at Zurich University of Applied Sciences, where I am currently studying the carbohydrate active enzymes of anaerobic gut fungi.
