The recombinant endoglucanase IV (Cel5; encoded by egIV) of Ruminococcus albus was compared with protein Cel5-CBM6 comprised of Cel5 fused at the C-terminus with the single-cellulose binding domain II (CBM6) of Clostridium stercorarium xylanase A, in order to improve its binding ability. Previous analyses using ball-milled cellulose had suggested that a(More)
Hydrolysis of cellulose requires two different types of cellulases: exo- and endocellulase. Here, we investigated for the hydrolysis of cellulose by two types of cellulases, an endoglucanase (Cel5) from Ruminococcus albus fused with the xylanase A cellulose binding domain II (CBM6) of Clostridium stercorarium and Thermobifidus fusca E3, an exoglucanase(More)
The purpose of this research is to develop and characterize a novel biomimetic nanocomposite that closely mimics the properties of real bone such as morphology, composition and mechanical characteristics. This novel porous nanocomposite is composed of cotton-sourced cellulose microcrystals, hydroxyapatite nanoparticles and poly l-lactide acid. A unique(More)
Lignocellulosic materials derived from forages, namely timothy grass, alfalfa, reed canary grass, and agricultural residues, such as corn stalks and barley straw, were pretreated using ammonia fiber explosion (AFEX) process. The pretreated materials were directly saccharified by cellulolytic enzymes. Sixty to 80% of theoretical yield of sugars were obtained(More)
