Abstract: The present invention relates to a method for preparing a concentrated polysaccharide mass, in particular a method for preparing concentrated glucan or schizophyllan, in particular a method for redispersing glucan or schizophyllan for producing a ready-to-use mass.

Abstract: The presently claimed invention is directed to a method for the preparation of an aqueous solution comprising at least one beta-glucan comprising at least the steps of a) fermentation of at least one fungal strain in an a fermentation broth, b) addition of at least one acid to the fermentation broth to adjust the pH to a value in the range of ?2.0 to ?4.0 and c) filtration of the fermentation broth to obtain an aqueous solution comprising the at least one beta-glucan and at least one beta-glucan that is obtained by this method.

Abstract: Fermenter for producing a shear-thinning medium comprising a tank volume and a stirring arrangement having an improved distribution capacity or a more uniform shear stress.

Abstract: The presently claimed invention relates to a method for concentrating a beta-glucan comprising at least the following steps: (a1) contacting an aqueous beta-glucan solution having a concentration [c1] with at least one precipitating agent p1 to obtain a precipitated beta-glucan in a solvent mixture comprising water and the at least one precipitating agent p1; (b1) separating the precipitated beta-glucan from the solvent mixture comprising water and the at least one precipitating agent p1 to obtain a precipitated beta-glucan having a concentration [c2]; and (c1) applying force to the precipitated beta-glucan of (b1) to obtain a precipitated beta-glucan having a concentration [c3].

Abstract: The present invention relates to a process for the fermentation of fungal strains which secrete glucans with a ?-1,3-glycosidically linked main chain and side chains ?-1,6-glycosidically bonded thereto, in a cascade of tanks using high-shear mixers.

Abstract: A bioreactor for cultivating phototrophic microorganism, includes a transparent upper plate and a lower plate, the upper plate being disposed above and spaced apart from the lower plate and defining therebetween a continuous cultivation volume having an inlet port and an outlet port, each of the plates including a plurality of parallel-facing deformations including peaks and troughs disposed in a regularly repeating geometric pattern. Further, a method of operating the bioreactor includes supplying a liquid culture of phototrophic microorganisms in the cultivation volume, supplying the microorganisms with nutrients, incubating the culture in daylight and harvesting at least one of the microorganisms and metabolites that have diffused into the culture medium are harvested.
