摘要:
Protein-rich nutrient supplements and animal feed supplements derived from an anaerobic bacterial process are generated through a myriad of cell rupturing and protein fractionation/purification processes. Bacterial fermentation systems and methods of obtaining one or more protein-containing portions from a fermentation process using carbon monoxide-containing gaseous substrates are provided. The invention further provides compositions of protein-rich nutrient supplements with useful applications for intake by a variety of different animals and humans.
摘要:
Acoustophoretic devices for separating particles from a non-flowing host fluid are disclosed. The devices include a substantially acoustically transparent container and a separation unit, with the container being placed within the separation unit. An ultrasonic transducer in the separation unit creates a planar or multi-dimensional acoustic standing wave within the container, trapping particles disposed within the non-flowing fluid and causing them to coalesce or agglomerate, then separate due to buoyancy or gravity forces.

摘要:
Methods, kits and reagents are provided for increasing the sensitivity of detecting the presence or absence of endospores by increasing the available protein for detection. The methods are fast and amendable to testing in a non-laboratory setting and use a protein detection reagent and solid microparticles.
摘要:
A bacterial spore comprising a modified prkC protein, wherein the extracellular domain of the modified prkC protein binds an agent which is not bound by the extracellular domain of the wild- type prkC protein, and wherein the agent is a germinant that stimulates germination of the bacterial spore, or a bacterial spore comprising a modified gerA protein, wherein the gerA protein has been modified such that the spore undergoes germination in the presence of a germinant which does not stimulate germination of a bacterial spore comprising wild- type gerA protein.
摘要:
La présente invention concerne un milieu réactionnel comprenant au moins un substrat de beta-glucosidase, et un composé de formule générale Ar-beta-D-glucoside, où Ar- désigne un composé aromatique, différent dudit substrat. Selon l'invention, un tel milieu peut être mis en œuvre dans un procédé de détection et/ou d'identification de C. difficile .
摘要:
A highly viable source of conidia of Botrytis cinerea, suitable for the botrytization of grapes is described. The invention relates to an aqueous composition comprising: conidia of Botrytis cinerea, at least one C3-6 polyol, and at least one monobasic alkaline salt, as well as pre formulates to obtain the same. Methods to perform a botrytization of a grapes, and methods to obtain a botrytized wine using the present compositions are also described.

The present invention provides isolated nucleic acid and amino acid sequences of Candida glabrata beta-tubulin, antibodies to C. glabrata beta-tubulin, and methods of screening to identify antifungals using biologically active C. glabrata beta-tubulin.
摘要:
A lanthanide is combined with a medium to be tested for endospores. The dipicolinic acid released from the endospores binds the lanthanides, which have distinctive emission (i.e., luminescence) spectra, and are detected using photoluminescence. The concentration of spores is determined by preparing a calibration curve that relates emission intensities to spore concentration for test samples with known spore concentrations. A lanthanide complex is used as the analysis reagent, and is comprised of lanthanide ions bound to multidentate ligands that increase the dipicolinic acid binding constant through a cooperative binding effect with respect to lanthanide chloride. The resulting combined effect of increasing the binding constant and eliminating coordinated water and equilibria increase the sensitivity of the endospore assay by an estimated three to four orders of magnitude over prior art of endospore detection based on lanthanide luminescence.
摘要:
The subject invention provides novel and advantageous methods for growing bacteria. The methods of the subject invention are particularly advantageous for growing parasitic bacteria, in vitro , without the presence of host tissue. In one embodiment of the subject invention, Pasteuria spores, such as those that infect the rootknot nematode Meloidogyne arenaria or other host nematodes, are grown in vitro . The process of the subject invention is highly advantageous because Pasteuria can be grown in the absence of nematode tissue.
