Abstract
The deuteration of organic molecules is considerably important in organic and medicinal chemistry. An electrochemical membrane reactor using proton-conducting graphene oxide (GO) nanosheets was developed to synthesize valuable deuterium-labeled products via an efficient hydrogen-to-deuterium (H/D) exchange under mild conditions at ambient temperature and atmospheric pressure. Deuterons (D+) formed by the anodic oxidation of heavy water (D2O) at the Pt/C anode permeate through the GO membrane to the Pt/C cathode, where organic molecules with functional groups (C≡C and C═O) are deuterated with adsorbed atomic D species. Deuteration occurs in outstanding yields with high levels of D incorporation. We also achieved the electrodeuteration of a drug molecule, ibuprofen, demonstrating the promising feasibility of the GO membrane reactor in the pharmaceutical industry.

Abstract
A bacterial strain, Pseudomonas bohemica strain ins3 was newly isolated as a resistant strain against high concentrations of hinokitiol. This strain was revealed not only to show resistance but also completely remove this compound from its culture broth. In addition, its mechanism was revealed to be independent of conventional aromatic dioxygenases, ie catechol-1,2- or 2,3-dioxygenases.
