説明

The oxidative activities of the acetic acid bacteria for the various carbohydrates were again determined. The substrates used were glucose, K-gluconate, Ca-2-ketogluconate, sucrose, L-arabinose, mannitol, fructose, sorbose, Na-succinate, Na-acetate, ethanol and amyl alcohol, which were typically selected from many carbohydrates according to the results obtained until 1955 in our investigation.<br> Thus some variations were discussed on the characters of the acetic acid bacteria.<br> The result is shown in Table II. Then the acetic acid bacteria were divided into five groups; Acetobacter group (typical species: A. aceti) which oxidized strongly ethanol and succinate, the pigment-producing group I (typical species: A. aurantium) which oxidized also succinate and thus was a noteworthy group as the intermediate type between Acetobacter and Gluconobacter, the pigment-producing group II (typical species: A. melanogenum) which did not oxidize succinate, Gluconobacter group I (typical species: A. oxydans) which could produce both 2-and 5-ketogluconates, and Gluconobacter group II (typical species: A. suboxydans var. α) which oxidized only weakly ethanol and produced mainly 5-ketogluconate.<br> Thus, the reality of the intermediate strains reported by Asai et al.(12) was confirmed independently.<br> The typical pattern of carbohydrates oxidation of each group is shown in Fig. 2_??_7.<br> In comparison with the results obtained until 1955, the variations were recognized on the oxidizability for carbohydrates and on the ketogenic character in some species or strains. These findings are shown in Tables II and III.
