| Abstract: | Changes in the isoenzymatic patterns of alcohol dehydrogenase (EC 1.1.1.1) accompanying ageing of the lupine root nodules were observed. Ethanol and other products of anaerobic metabolic pathways (lactate and malate) are better respiratory substrates for bacteroids and symbiosomes (peribacteroid units, PBUs) than glucose and pyruvate. It is postulated that fermentative processes in lupine root nodule provide energy and substrates for bacteroids. |
