摘要:
The current invention provides a recombinant bacterium, the recombinant bacterium being genetically modified to decrease or eliminate the display of lipoteichoic acid (LTA), surface layer protein B (SlpB) and surface layer protein X (SlpX) on the surface of said bacterium. Efficacious therapies for a subject suffering from an inflammation mediated disease are also provided. The methods of the current invention comprise administering to a subject in need thereof a therapeutically effective amount of the recombinant L. acidophilus cells or a therapeutically effective amount of the isolated surface layer protein A (SlpA) or a non-naturally occurring derivative thereof. The recombinant L. acidophilus cells or SlpA isolated from L. acidophilus can be in a pharmaceutical composition comprising a pharmaceutically acceptable carrier and/or excipient. In an embodiment of the invention, the pharmaceutical composition is administered orally.
摘要:
The present invention relates to fermentation processes. The objective of the invention was to provide methods for producing nisin containing ferments and formulating such ferments into preservatives. It was in particular an object of the present invention to provide improved processes for producing nisin containing ferments by simple and efficient (batch) culturing and allowing for simple down-stream processing either into a liquid, semi-liquid or a dry powder product, having sufficient nisin content and stability, good handling properties and satisfactory organoleptic properties. Such processes are provided, as well as the products that can be obtained with it and their use.
摘要:
Recombinant bacteria capable of metabolizing sucrose are described. The recombinant bacteria comprise in their genome or on at least one recombinant construct, a novel nucleotide sequence encoding a polypeptide having sucrose transporter activity and a nucleotide sequence encoding a polypeptide having sucrose hydrolase activity. These nucleotide sequences are each operably linked to the same or a different promoter. Recombinant bacteria capable of metabolizing sucrose to produce glycerol and/or glycerol-derived products such as 1,3-propanediol and 3-hydroxypropionic acid are also described.

摘要:
TRFs useful for identifying strains of interest are provided. A method of identifying one or more strain that can be used as a direct-fed microbial is also provided. One or more strain identified by the method is additionally provided. A method is also provided for administering to an animal an effective amount of the one or more strain. Additionally provided is an isolated strain chosen from at least one of Lactobacillus acidophilus strain PlB C6 (NRRL B-50103), Lactobacillus salivanus strain o24όe 33w (NRRL B-50102), Pediococcus acidilactici strain o246e 42 (NRRL BoOl 71), and Pediococcus acidilactici strain PU e3 (NRRL B-50101). An isolated strain having all of the identifying characteristics of one of the strains listed above is also provided. One or more strain can be administered as a direct-fed microbial to an animal. Methods of preparing a direct-fed microbial are also provided.
摘要:
This invention provides isolated and characterized secreted molecules from probiotic bacteria from the genera Lactobacillus, Lactococcus, Streptococcus or Bifidobacterium for use in compositions and methods for the treatment and/or prevention of infection by harmful pathogenic bacteria such as Salmonella or E.coh The isolated secreted molecules can also be used in nutritional or medical food products which provide probiotics to the gastrointestinal tract of a mammal
