Recalcitrance of biomass feedstock remains a challenge for microbial conversion of lignocellulose into biofuel and biochemicals. Clostridium cellulosi, one thermophilic bacterial strain dominated in compost, could hydrolyze lignocellulose at elevated temperature by secreting more than 38 glycoside hydrolases belong to 15 different families. Though one(More)
Glycoside hydrolase (GH) family 5 is one of the largest GH families with various GH activities including lichenase, but the structural basis of the GH5 lichenase activity is still unknown. A novel thermostable lichenase F32EG5 belonging to GH5 was identified from an extremely thermophilic bacterium Caldicellulosiruptor sp. F32. F32EG5 is a bi-functional(More)
β-1,3-Glucans, important structural components of cell wall or nutritional components of the endosperm, are extensively found in bacteria, fungi, yeast, algae, and plants. The structural complexity of β-1,3-glucans implies that the enzymatic depolymerization of polysaccharides needs combined activities of distinct enzymes. In this study, Lam16A-GH, the(More)
