Process for producing exocellular biopolymers

Abstract

Abstract 1. A process for the production of biopolymers by aerobic culturing of microorganisms in an aqueous mutrient medium, in which the microorganisms are cultured in a water-in-oil emulsion (W/O emulsion) stable under fermentation conditions, characterized in that exocellular biopolymers having a thickening effect on microorganism strains which form the aqueous nutrient medium and which are derived from the following bacteria and yeast species or geni are cultured : Bacillus spp. Leuconostoc spp. Streptococcus mutans Streptococcus spp. Azotobacter spp. Rhizobium spp. Escherichia coli Klebsiella aerogenes Azotobacter xylinum Arthrobacter viscosus Pseudomonas aeruginosa Achromobacter spp. Alcaligenes faecalis var. myxogenes Agrobacterium spp. Erwinia spp. Sphaerotilus natans Rhodotorula spp. Pichia spp. Pachysolen tannophilus Lipomyces spp. Hansenula capsulata Hansenula holstii Cryptococcus spp. Torulopsis molischiana Torulopsis pinus Aureobasidium pullulans.
