  • Patent number: 8129147
    Abstract: Methods for producing quadrivalent meningococcal meningitis polysaccharide and conjugate vaccines for serotypes A, C, Y and W-135 disclosed. Neisseria meningitidis fastidious medium was designed to maximize the yield of capsular polysaccharides and generate minimal cellular biomass and endotoxin in a short duration of fermentation. The crude polysaccharides are isolated, purified, and mechanically depolymerized by sonication. These purified polysaccharides were found in human clinical trials to be safe and immunogenic against meningococcal disease caused by N. meningitidis A, C, Y and W-135 serogroups in sub-Saharan Africa. In the preferred embodiment, the polysaccharides are conjugated to carrier proteins of diphtheria or tetanus toxiod to an average molecular size of 5100 to 9900 Daltons and provide broad spectrum protection to humans of all ages. Accelerated polysaccharide production and the efficacy of the resulting vaccine are demonstrated.

  • Publication number: 20120027888
    Abstract: Protein in an aqueous whey solution is degraded by adding a protease to the aqueous whey solution. After that, a whey degradation medium is prepared by adding yeast extract or the like to the aqueous whey solution. The whey degradation medium is inoculated with bacteriocin-producing lactic acid bacterium and the lactic acid bacterium is cultured while the whey degradation medium is maintained at pH of not lower than 5 and not higher than 6. After the completion of the culture, the whey degradation medium (culture solution) is centrifuged to thereby separate a concentrated cell suspension containing the lactic acid bacterium in a concentrated form. The concentrated cell suspension has extremely high antibacterial activity (several tens of thousands AU) and is usable as a food preservative. Further, yogurt is produced by fermenting a yogurt mix to which 0.01% to 0.1% by weight of the concentrated cell suspension is added. With this process, it is possible to suppress an increase in the acidity of the yogurt.

Further, polyoxyethylene sorbitan monooleate or propylene glycol monooleate is added to the whey degradation medium. The whey degradation medium is inoculated with bacteriocin-producing lactic acid bacterium and the lactic acid bacterium is cultured while the whey degradation medium is maintained at pH of 4 to 5. After the completion of the culture, the whey degradation medium (culture solution) is centrifuged to thereby separate therefrom a concentrated cell suspension containing the lactic acid bacterium in a concentrated form. The concentrated cell suspension has very low antibacterial activity (several tens AU or less). Then, by adding the concentrated cell suspension to a yogurt mix and fermenting the same, it is possible to produce yogurt containing the bacteriocin-producing lactic acid bacterium without any delay in the fermentation.

The control sample is grown with a nutrient having an isotope of a first atom, whereas the experimental sample is grown with a nutrient having a second isotope of the first atom. The experimental sample is grown with a stressing agent and regimen. The samples are admixed, and the formed composite is mass spectroscopically assayed for analyte peaks. The ratio of first isotope to second isotope is determined for the peaks, as is a sample median isotopic ratio. The ratio for assayed analyte peaks is compared with the median ratio. An analyte whose isotopic ratio significantly deviates from the median ratio is an analyte affected by the stressing agent.

  • Publication number: 20110027866
    Abstract: The method provides a simple, accurate and inexpensive way to prepare culture media for conducting microbiological analysis with an absolute minimum of facilities, extraneous equipment and time consuming procedures. The invention introduces the use of a carrier piece that is suitable for carrying a reactant material for combining with growth media. The carrier piece may be formed using (non-)porous, (non-)absorbent material, including paper, plastic, gum, fabric, or acetate. The carrier piece carries a single one or a combination of various reactant materials that are released into the medium or medium/test sample mixture upon contact therewith. The reactant materials may include, among other things, nutrients, inhibitors, including antibiotics and bile salts, enzyme substrates, and/or a catalyst for a gelling agent contained in the growth medium.

  • Publication number: 20110014661
    Abstract: The present invention relates to a method for the large scale in vivo synthesis of sialylated oligosaccharides, culturing a microorganism in a culture medium, optionally comprising an exogenous precursor such as lactose, wherein said microorganism comprises heterologous genes encoding a CMP-Neu5Ac synthetase, a sialic acid synthase, a GlcNAc-6-phosphate 2 epimerase and a sialyltransferase, and wherein the endogenous genes coding for sialic acid aldolase (NanA) and for ManNac kinase (NanK) have been deleted or inactivated. The invention also relates to these micoorganisms which are capable of producing internally activated sialic acid.

  • Patent number: 7842496
    Abstract: Selective growth media N4 agars that include a combination of high levels of yeast extract, possibly higher levels of protein, elevated levels of sugar and reduced levels of sodium chloride. The combination of ingredients provides the ability to detect Salmonella spp. and Shigella spp. with almost identical sensitivity while alleviating false-negative and false-positive problems commonly encountered with the presence of Proteus spp. and Citrobacter spp.

  • Publication number: 20100297166
    Abstract: Methods for producing quadrivalent meningococcal meningitis polysaccharide and conjugate vaccines for serotypes A, C, Y and W-135 disclosed. Neisseria meningitidis fastidious medium was designed to maximize the yield of capsular polysaccharides and generate minimal cellular biomass and endotoxin in a short duration of fermentation. The crude polysaccharides are isolated, purified, and mechanically depolymerized by sonication. These purified polysaccharides were found in human clinical trials to be safe and immunogenic against meningococcal disease caused by N. meningitidis A, C, Y and W-135 serogroups in sub-Saharan Africa. In the preferred embodiment, the polysaccharides are conjugated to carrier proteins of diphtheria or tetanus toxoid to an average molecular size of 5100 to 9900 Daltons and provide broad spectrum protection to humans of all ages. Accelerated polysaccharide production and the efficacy of the resulting vaccine are demonstrated.

  • Publication number: 20100267999
    Abstract: A method for producing a microbial growth stimulant (MGS) from a plant biomass is described. In one embodiment, an ammonium hydroxide solution is used to extract a solution of proteins and ammonia from the biomass. Some of the proteins and ammonia are separated from the extracted solution to provide the MGS solution. The removed ammonia can be recycled and the proteins are useful as animal feeds. In one embodiment, the method comprises extracting solubles from pretreated lignocellulosic biomass with a cellulase enzyme-producing growth medium (such T. reesei) in the presence of water and an aqueous extract.

  • Patent number: 7807439
    Abstract: The invention concerns a medium for specific detection of Staphylococcus aureus and/or discrimination between positive-coagulase Staphylococcus and negative-coagulase enabling Staphylococcus to isolate bacteria of the genus staphylococcus and identify the Staphylococcus aureus species, which use at least an enzymatic substrate, preferably a chromogenic or fluorescent agent, and still more preferably consisting of an indoxyl or naphthol base. The invention also concerns a method for identifying, and optionally counting, Staphylococcus aureus using such a medium. It consists of a Staphylococcus aureus culture medium and at least an enzymatic substrate enabling testing of an ?-glucosidase activity. The invention is particularly applicable in the field of diagnosis.
