Abstract: The present invention describes an efficient way to isolate a sialic acid from a fermentation broth. The sialic acid contained in the fermentation broth is produced by bacterial fermentation. The inventive process comprises a step of removing biomass from the fermentation broth, a step of subjecting the resulting solution to at least one of a cationic ion exchanger treatment and an anionic ion exchanger treatment and a step of removing salts after the ion exchanger treatment. The process can provide the sialic acid in spray-dried form as well as in form of sialic acid crystals.
Abstract: The present disclosure relates to a process for electrostatic spray drying of a living microorganism, the process comprising the following steps: a. Providing a suspension, comprising a number of components, including a microorganism, a solvent and an additive; b. Applying an electrostatic charge to said suspension; c. Forming droplets of said suspension; d. Drying said droplets, thereby forming dried particles; and e. (Optionally) collecting the dried particles.

Abstract: The present invention relates to microencapsulated microbial cultures with high storage stability and methods for producing these. In particular, the present invention relates to microbial cultures formulated in complex coacervates comprising octenyl succinic anhydride (OSA) starch and chitosan, products comprising such formulations.
Abstract: Disclosed are genetically-engineered gram-negative bacterial cells for the production of an oligosaccharide of interest, wherein the bacterial cell possesses a saccharide transporter and/or a porin being expressed from a recombinant gene or a deregulated endogenous gene, thereby facilitating the translocation of the oligosaccharide of interest from the cell's cytoplasm into the cell's environment. Also disclosed are methods for producing an oligosaccharide of interest which used said genetically-engineered gram-negative bacterial cells.

Abstract: The present invention concerns an efficient way to isolate L-fucose from a fermentation broth. The L-fucose contained in the fermentation broth is produced by microbial fermentation (bacterial or yeasts). The inventive process comprises a step of removing biomass from the fermentation broth, a step of subjecting the resulting solution to at least one of a cationic ion exchanger treatment and an anionic ion exchanger treatment and a step of removing salts after the ion exchanger treatment. The process can provide L-fucose in powder form, in granulated form as well as in form of L-fucose crystals.
Abstract: The present invention relates to a composition suitable for preparing a dairy product comprising at least one starter culture and a Lactobacillus rhamnosus strain capable of imparting onto the dairy product an enhanced creamy flavor without affecting the rheology negatively, the fermentation time or the post-acidification of the dairy product. The present invention further relates to processes for preparing a dairy product, such as a low-fat yogurt or cheese, which has a high content of diacetyl. A Lactobacillus rhamnosus strain useful for preparing such dairy product is also part of the present invention.
