Ecological factors and adaptive processes in N2-fixing bacterial populations of the plant environmen. Nevertheless, understanding the ecology of diazotrophs cannot be achieved by studying only laboratory micro-organisms. It is necessary to study naturally-occurring populations, to characterize their densities, size, composition, variability and variations in order to understand how a plant can sel

Growth and survival of , and , in binary continuous cultureduring nutrient starvation were examined at various dilution rates. At D = 0.05 h., K. values for succinate consumed were calculated. . viability was inversely related to dilution rate whereas . was directly related. Slightly lower values of viability were obtained in mixed culture, but the ratio be

Enrichment of diazotrophic bacteria from rice soil in continuous culture microaerobic conditions (8.7 µmol 0./l) with malate as the sole carbon source. The starting material was a Korean rice soil including intact root pieces. The enrichment process was governed by the dilution rate. High dilution rates resulted in the enrichment of ., whereas low dilution rates led to

Biochemistry and physiology of nitrogen fixation with particular emphasis on nitrogen-fixing phototrms. Evidence suggests that fixed carbon dissimilation rather than direct photoreduction from oxidised inorganic compounds or exogenous photosynthetic electron donors is the major route of reductant supply to nitrogenase in phototrophs; in . pyruvate is a possible electron donor to nitrogenase; in cy
