Abstract
In Azorhizobium caulinodans strain IRBG 46, H2 evolved by nitrogenase Induced uptake hydrogenase ex-planta. The strain expressed an efficient H2 recycling system under both symbiotic and ex-planta conditions. For the first time, a comparable relative efficiency of electron transfer to N2 via nitrogenase under symbiotic as well as ex-planta conditions for both Hup− strain B11 as well as Hup+ strain IRBG 46, has been reported. The study also suggested a coordinate regulatory relationship between rubisco and hup genes.
