Bacillus stearothermophilus strain BR325 demonstrating broad aromatic substrate capability was isolated from petroleum-contaminated soil. The chromosomally-located aromatic pathway from this isolate was cloned into Escherichia coli as a 32 kb insert in cosmid pHC79, conferring growth on benzene, phenol, and toluene as sole carbon sources.
This study was aimed at improving the gas barrier property of sugarcane based LLDPE using cellulose nanocrystals (CNCs). Specifically, this study evaluated the effect of CNC content on the crystallinity, tortuosity factor, carbon dioxide permeability (P CO2 ), and/or oxygen permeability (P O2 ) of bio-LLDPE sheets and films. All nanocomposites showed considerable improvement in gas barrier irrespective of the CNC content. The P CO2 coefficient of LLDPE sheets
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
