WebStudies of • OH distribution in Taurus Molecular Cloud-1 (TMC-1) [32] suggest that in dense gas, • OH is mainly formed by dissociative recombination of H 3 O +. Dissociative recombination is the reaction in which a molecular ion recombines with an electron and dissociates into neutral fragments. Important formation mechanisms for • OH are: Webthese reactions by performing hydrogenations under an atmosphere of hydrogen gas in growth media containing E. coli DD-2 (optical density OD 600 =0.4). This engineered strain produces hydrogen from glucose using an inducible pathway consisting of a pyruvate ferredoxin oxidoreductase, a ferredoxin,anda [Fe-Fe] hydrogenase.[13] Weobserved little
