A slimy non-spore-forming bacterium strain 10C3 isolated from soil was motile with peritrichous flagella and named Alcaligenes faecalis var. myxogenes. Studies were made on the conditions necessary for maximal production of a new acidic succinoglucan polysaccha-ride by this strain in shaken cultures. Much production was observed with sucrose, glucose, xylose, galactose, cellobiose, maltose, fructose, mannose and rhamnose. The yield was greatest with sucrose and decreased in order with the above sugars from about 36 to 23 per cent. The most suitable medium contained 4 per cent sugar, 0.5 per cent yeast extract and one per cent calcium carbonate in tap water. The optimum temperature was 28°C.
