DOI: 10.1002/biot.201600450
Abstract: An esterase from Clostridium botulinum (Cbotu_EstA) previously reported to hydrolyze the biodegradable polyester poly(butylene adipate-co-terephthalate) was redesigned to improve the hydrolysis of synthetic polyesters. Increased activity was indeed observed for del71Cbotu_EstA variant, which performed activity… read more here.

DOI: 10.1002/btpr.3059
Abstract: A comprehensive review of the literature shows that enzyme hydrolysis efficiency decreases with increased solids loadings at constant enzyme:cellulose ratios for pretreated lignocellulosic substrates. In seeking a mechanistic explanation for this phenomenon, we found that… read more here.

DOI: 10.1002/cssc.201700032
Abstract: Urea tends to be hydrolyzed by urease and then migrate into the environment, which results in a low utilization efficiency and severe environmental contamination. To solve this problem, a network-structured nanocomposite (sodium humate-attapulgite-polyacrylamide) was fabricated… read more here.
