1531644 Xanthomonas polysaccharides RHONE POULENC INDUSTRIES 23 Feb 1977 [26 Feb 1976] 07670/77 Heading C3U A process for producing polysaccharides comprise3 fermenting a glucide by a microorganism of the genus Xanthomonas wherein after the initial preparation of the inoculum a fermentation medium containing ammonium phosphate as the sole source of nitrogen is used for the subsequent fermentation stage or stages. The ammonium phosphate is usually used at a concentration of 1-6 g./l. expressed as diammonium phosphate and the preferred microorganism is X. campestris.
