Abstract: The present invention provides a process for spray freezing or spray freeze drying under conditions of very low oxygen pressure, such as under essentially anaerobic conditions, and particularly a process for spray freezing strict anaerobic microorganisms (bacteria) under conditions where the level of oxygen is very low, or essentially anaerobic. Further, the invention provides a product achievable by the processes and an apparatus usable in the process.
Abstract: The present invention relates to the field of frozen or dry compositions for prokaryotes, in particular fermentative bacteria such as lactic acid bacteria, a method for preparing frozen or dry prokaryotic compositions and compositions which may be prepared by said method. The cells in a cell concentrate are activated by allowing them to ferment a carbohydrate, before freezing and/or drying to provide a product. The hydrophobicity of the cell surface increases during activation, and this has been found to increase the storage stability of the product.

Abstract: Disclosed are non-naturally-occurring microorganisms for the production of N-acetylneuraminic acid, a method for the production of N-acetylneuraminic acid by fermentation of the non-naturally-occurring microorganisms, and nutritional compositions containing N-acetylneuraminic acid which has been produced by fermentation of the non-naturally-occurring microorganisms.
Abstract: Disclosed is a method for purifying sialylated oligosaccharides from a fermentation broth, cell-lysate or biocatalytic reaction mixture for obtaining high amounts of desired sialylated oligosaccharides in high purity. The method is particular suitable for the large-scale economic purification of sialylated human milk oligosaccharides (such as 3?-sialyllactose, 6?-sialyllactose or sialylated lacto-N-tetraose derivatives) from microbial fermentation, using recombinant bacterial cells or yeast cells. The obtained material is of high purity and can be used for food or medical application such like medical nutrition products, infant formula, dietary supplements, general nutrition products (e.g. dairy drinks).

Abstract: The present invention relates to a process for making low-moisture mozzarella cheese using recent developments in the technical knowledge about the interactions between cultures, coagulants and cheese technology to increase cheese yields and maintain the cheese quality and functionalities. An optimization may lead to a higher pH and higher dry matter of the curd at the whey off step i.e. pH higher than 6.3 and ideally higher than 6.4 and solid non-fact content higher than 18%, without any modification of the curd composition at the stretching step, i.e. pH between 5.0 and 5.3 and more precisely between without any modification of the curd composition at the stretching step, i.e. pH between 5.0 and 5.3 and more precisely between 5.05 and 5.25, Ca/SNF between 1.7% and 2.4% and more precisely between 1.7 and 2.2%, dry matter between 53% and 55% and more precisely between 53.5% and 54.5%. The coagulant has a C/P ratio of at least 25.
Abstract: The present invention relates to a method for producing fucosylated oligosaccharides by using a recombinant prokaryotic host cell that is cultivated on a gluconeogenic substrate, as well as to the host cell and its use. The host cell is genetically modified in that the activity of a fructose-6-phosphate converting enzyme is abolished or lowered, and the transport of the produced fucosylated oligosaccharide through the cell membrane is facilitated by an exogenous transport protein.

Abstract: The present invention relates to encapsulation of microbial cultures to improve the robustness and stability upon storage. In particular, the present invention relates to dry preparations of microbial cultures, such as lactic acid bacteria (LAB), coated by a fat-matrix that increase survivability and mitigate post-acidification upon storage at ambient temperature for extended periods of time.
Abstract: Present invention relates to dried lactic acid bacteria compositions are stabilised with synergistic mixtures of stabilisers selected from oligofructans, maltodextrin, inulin and pea fibre. The mixtures have been found to stabilise the compositions during the drying (e.g. freeze-drying) process and during storage.
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.
