Zusammenfassung:	A process for the production of polysaccharide consisting of a partially acetylated variable block copolymer of D-mannuronic and L-guluronic acid residues, comprises cultivating in a nutrient medium therefor a strain of Pseudomonas, which is non-pathogenic to humans, and which has been obtained by treating a non-mucoid species of Pseudomonas, which is non-pathogenic to humans, with a beta -lactam or aminoglycoside antibiotic whereby a mucoid strain tolerant to said antibiotic was selected, and isolating from the medium the polysaccharide produced.
