Abstract

Process for the extracellular preparation of homopolysaccharides of molecular weight 5 to 25 million with, in the main chain, exclusively beta -1,3-D-glucopyranose units, of which each third is beta -1,6-glycosidically linked to another glucose unit, characterised in that microorganisms in the form of at least one of the fungal strains DSM 6318, DSM 6319 and DSM 6320 are cultured in a nutrient medium with aeration and agitation at a temperature in the range from 15 to 40 DEG C, then the culture solution is separated from the biomass, and the water-soluble homopolysaccharide which is formed is isolated therefrom in a conventional manner, and the said fungal strains and the use of the polysaccharides, are described.
