“…All strains were Gram-stain-negative and shared the following characteristics: catalase activity, ethanol oxidation, ketogenesis from glycerol, formation of 2-keto- d -gluconic acid and glucuronic acid from glucose, acid production from d -arabinose, d -fructose, d -glucose, d -galactose, d -mannitol, d -mannose, d -ribose, d -xylose, ethanol, glycerol, melibiose and meso-erythritol. All results, except for the formation of 2-keto- d -gluconic acid and glucuronic acid from glucose for Gluconobacter aidae AC 10 T [29], were obtained in the present study. The following characteristics were uniformly absent: oxidase activity, growth in SM medium with 2 % NaCl and growth in 30 % d -glucose, growth on d -ribose, d -xylose, dulcitol, ethanol, l -arabitol, methanol, raffinose and sodium acetate as the sole carbon source.…”
