Production and rheological properties of a succinoglycan from Pseudomonas sp. 31260 grown on wood hydrolysates.
Pseudomonas sp. ATCC 31260 produced substantial amounts of anionic extracellular polysaccharide (EPS) from a mineral acid hydrolysate of wood, prepared using the "Tennessee Valley Authority" process. Partially purified EPS production approached 16.5 g/L (as hexadecyltrimethylammonium bromide precipitate) when the pH of the hydrolysate was initially adjusted to 7.5 and amended with 0.05% each of peptone and yeast extract. This EPS, now characterized as a succinoglycan, is composed of glucose, galactose, succinate, pyruvate, and acetate. Solutions of this EPS are pseudoplastic, and under specified conditions, are rheologically comparable with commercially available xanthan.
