The expression and maintenance of nitrogenase (C(2)H(2)) activity in growing, microaerobic liquid cultures of Rhizobium japonicum 3I1b110 was found to be stringently dependent on the sustained supply of CO(2). This requirement for CO(2) appeared to exceed the basal requirement for growth and was not related to effects on pH.
