The hydrolysis of cellulose into fermentable sugars is a costly and rate-limiting step in the production of biofuels from renewable feedstocks. Developing new cellulase systems capable of increased cellulose hydrolysis rates would reduce biofuel production costs. With this in mind, we screened 55 fungal endoglucanases for their abilities to be expressed at(More)
Alcaligenes faecalis penicillin G acylase is more stable than the Escherichia coli enzyme. The activity of the A. faecalis enzyme was not affected by incubation at 50 degrees C for 20 min, whereas more than 50% of the E. coli enzyme was irreversibly inactivated by the same treatment. To study the molecular basis of this higher stability, the A. faecalis(More)
Endo-1,4-β-xylanases (EC hydrolyze the 1,4-β-D-xylosidic linkages in xylans, the most abundant hemicellulose in plant cell walls. Xylanase enzymes have numerous industrial applications, including the manufacturing of animal feed, bread, juice and wine, pulp and paper, and biofuels. In this study, two glycosyl hydrolase family 10 members designated(More)
