Abstract: By substituting biomass with a surface-active substance in a fermentation broth containing amino acid before spray-drying, granulated animal feed additives with improved product specifications were obtained.

Abstract: Process for fluidized bed granulation of amino acid-containing fermentation broths comprising the steps Introduction of a drying gas with a temperature of 100° C.-450° C. into the fluidized bed granulation chamber Spraying of the amino acid-containing fermentation broth into the fluidized bed granulation chamber Discharge of the granules granulated in the fluidized bed granulation chamber with the drying gas stream, and drying of the discharged granules in a fluidized bed drying step, wherein the discharged granulated granules are a granule mixture with various particle sizes and contains an oversize fraction, wherein the oversize comprises the particle sizes which lie above a desired particle size, an wherein the oversize fraction is removed from the discharged granule mixture and then comminuted and the comminuted oversize and the granule mixture from which the oversize was separated are fed into the fluidized bed drying step.

Abstract: The invention relates to cells and a method for producing acetone.

Abstract: The invention relates to a method for producing a low-molecular-weight organic compound, such as acetone, butanol, and ethanol, in a fermentation process. The method contains a step of introducing a gas flow into an aqueous solution containing microorganisms producing the low-molecular-weight organic compound; a step of recovering the gas flow through a compound comprising isophoron; and optionally a step of separating the low-molecular-weight organic compound from the composition comprising isophoron.

Abstract: The invention relates to a method comprising the following method steps: A) providing an aqueous solution comprising microorganisms producing low-molecular, organic compounds; B) introducing at least one gas or gas mixture into the aqueous solution; C) recovering the gas flow through a compound comprising an isophoron; and optionally D) separating the low-molecular, organic compound from the composition comprising the isophoron.

Abstract: The invention relates to a granular fermentation-broth-based feed additive, comprising an L-amino acid selected from the group consisting of L-lysine, L-methionine, L-threonine, L-tryptophan, L-valine or mixtures of these, suitable for the preparation of feeds for animals kept in aquaculture, where the content of the L-amino acid or the mixtures thereof amount to 20% by weight of the total composition of the granular feed additive; where at least 70% by weight of the particles have a particle diameter of from >63 ?m to <300 ?m, where the biomass content amounts to ?5% by weight and where the surface of the particles is fully or partially coated with an edible oil, wherein the L-amino acid is L-lysine, is present as a sulphate salt and the molar ratio of sulphate to L-lysine amounts to at least 0.5.
