Abstract: The rapid growing bio-refining industry is hindered by the slow reaction rate of cellobiohydrolase catalyzed hydrolysis. Analysis of the mechanism of enzyme interaction in the ...

ABSTRACT: Many nanoparticles have been created over the last few decades using a variety of techniques and used to develop environmental technology, including water treatment, the detection of ...

The pH-rate profile (log kobs = f(pH)), shows that the hydrolysis reaction of the LAS, is conducted by a catalysis acid-base mechanism, with multiple reaction pathways. The rate constants, kH, kOH and ...

Bifunctional acid−base catalysts are highly desirable for industrially relevant chemical processes. Owing to their ability to activate electrophiles and nucleophiles simultaneously, they allow the ...

The high efficiency of cellulase-catalyzed cellulose hydrolysis is due to not just the unique structural configuration of the catalytic site but also the assistance of the CBD in associating cellulase ...
