Here, we report the 4.12-Mb draft genome sequence of Arthrobacter sp. strain 7749, isolated from marine sediment samples of the Antarctic Peninsula, using enriched medium with (RS)-1-(4-phenyl)-ethanol as a carbon source. This genome sequence will provide relevant information for applications in enantioselective alcohol oxidation to improve industrial catalytic processes.
Applications of gold and selenium chemistry are reported as novel approaches to promote lignin depolymerization into more valuable chemicals via selective oxidation reactions (alcohol oxidations and Baeyer‐Villiger reactions). In this study, we proposed two different oxidative methodologies using Au/SiO2 and phenylseleninic acid resin (PAR) as stable and reusable catalysts to promote selective transformations of the β‐O‐4 linkage of lignin model compounds. After evaluating the catalytic systems under batch conditions, they were both applied in a packed‐bed reactor for continuous flow operations. By using Au/SiO2 as a catalyst under flow conditions, ketones were efficiently obtained (up to 86% conversion) from the oxidation of alcohols with a residence time (tR) of 30 min. In the case of Baeyer‐Villiger oxidations catalyzed by phenylseleninic acid resin, the corresponding esters were obtained in up to 91% conversion (tR=30 min). Both systems efficiently catalyzed the conversion of the lignin model compounds.magnified image
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.
