Patent number: 5849550Abstract: A method for producing lysocellin in bead form comprises:(a) cultivating a lysocellin-producing microorganism in an aqueous nutrient-containing fermentation broth under lysocellin-producing conditions;(b) adding a base or inorganic phosphate to the fermentation broth within about the first 24 hours of the beginning of the fermentation in an amount sufficient to ensure that the lysocellin is produced in the form of a cation salt of lysocellin;(c) providing a lipid to the fermentation broth such that the lipid is present in the broth in a sufficient amount to form discrete beads with the lysocellin in the fermentation broth; and(d) separating the beads from the broth.Type: GrantFiled: June 30, 1995Date of Patent: December 15, 1998Assignee: Mallinckrodt Veterinary, Inc.Inventors: Donald R. Hahn, James R. McMullen, Vikram P. Mehrotra

Patent number: 5849289Abstract: The antibiotic reuterin is obtained by cultivating strains of Lactobacillus reuteri under controlled conditions. Reuterin has inhibitory activity against Gram positive and Gram negative bacteria, against the yeast, Saccharomyces cerevisiae, and against the protozoan, Trypanosoma cruzi. Reuterin-producing strains are identified by growth inhibition of susceptible microorganisms in the presence of glycerol or glyceraldehyde. Lactobacillus reuteri strains may be used for reducing the number of non-Lactobacillus reuteri bacteria in food items and in the gastrointestinal tracts of animals.Type: GrantFiled: June 7, 1995Date of Patent: December 15, 1998Assignee: Biogaia Biologics ABInventors: Walter J. Dobrogosz, Sven E. Lindgren

Patent number: 5846743Abstract: Methods and compositions for facilitating the transport of a membrane-impermeable extracellular agent having an intracellular activity across the membrane of a cell are provided. The methods involve covalently coupling an amino terminal blocking group to a transport-mediating peptide to form a carrier molecule. The carrier molecule is covalently coupled to the extracellular agent to form a membrane-permeable prodrug. The transport-mediating peptides are highly basic and bind to polyphosphoinositides.Type: GrantFiled: November 22, 1996Date of Patent: December 8, 1998Assignee: Brigham and Women's Hospital, Inc.Inventors: Paul A. Janmey, C. Casey Cunningham, John H. Hartwig, Thomas P. Stossel, Roland Vegner

Patent number: 5846793Abstract: A process for preparing optically active (R)-3-chloro-1,2-propanediol, which comprises subjecting (R,S)-3-chloro-1,2-propanediol to the reaction of a microorganism belonging to genus Serratia in a reaction mixture, and then collecting the residual (R)-3-chloro-1,2-propanediol. According to the process of the present invention, (R)-3-chloro-1,2-propanediol can be efficiently prepared starting from low cost (R,S)-3-chloro-1,2-propanediol.Type: GrantFiled: December 27, 1990Date of Patent: December 8, 1998Assignee: Kanegafuchi Kagaku Kogyo Kabushiki KaishaInventors: Hideyuki Takahashi, Satoru Tsuda, Yoshio Nakamura, Masahiro Ogura, Tadayoshi Shiraishi, Yoshio Shimada, Kiyoshi Watanabe
