Abstract
Free-living cells of Rhizobium leguminosarum 3841 have inducible oxidation systems for the catabolism of histidine, malonate, p-hydroxybenzoate, glycerol, mannitol and sorbitol. In addition to p-hydroxybenzoate, strain 3841 is able to use a variety of other aromatic substrates as sole carbon source. Cultured free-living bacteria of this strain have constitutive systems for the catabolism of acetate, pyruvate, succinate, fumarate, malate, glucose, fructose, sucrose, lactose, ribose and arabinose. However, isolated pea bacteroids of the same strain are unable to oxidize monosaccharides or disaccharides although they can oxidize the organic acids succinate, fumarate, malate and pyruvate.
