D.YR 1980 T1 The Effects of Carbon Dioxide on Nitrogenase-related Activities of Rhodopseudomonas capsulata JF Microbiology, VO 119 IS 1 SP 281 OP 284 DO https://doi.org/10.1099/00221287-119-1-281 PB Microbiology Society, SN 1465-2080, AB N2 fixation was investigated in suspensions of washed cells of the photosynthetic bacterium Rhodopseudomonas capsulata grown on various carbon and nitrogen sources. Maximum nitrogenase activities were common to cultures supplied with glutamate. Cells grown with nitrate contained appreciable nitrogenase activity and produced H2 in the light. Nitrogenase activity in washed cells derived from various nutritional conditions was markedly increased when NaHCO3 was included in the reaction mixtures., UL https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-119-1-281
