Abstract

1531970 Producing xanthomonas colloids PFIZER Inc 5 Aug 1977 [5 Aug 1976 3 May 1977] 33003/77 Heading C3U A fermentation medium containing Xanthomonas hydrocolloids is obtained by cultivating aerobically a Xanthomonas microorganism, preferably X. compestris in an aqueous nutrient containing a carbohydrate, a nitrogen source and 0À1-10 g/l of an assimilable Krebs cycle acid, 1-200 p.p.m. of chelated calcium and 0À25-20 p.p.m. of iron, and trace elements until at least 100 p.p.m. of colloid is present whereby the whole broth produces mobility control solutions suitable for subterranean oil recovery which are free of insoluble matter having particle sizes of above 3 microns.
