Abstract: The present invention is directed to a method and means for the neutralization, binding, and/or inactivation of antimicrobials in a test sample. The invention is also directed to a method of detecting the presence of one or more microorganisms in a test sample by culturing the test sample in a culture media comprising one or more primary amine-containing compounds.
Abstract: The present invention relates to a method for enhancing growth of plants which comprises contacting a Trichoderma strain with the plant or a plant seed under conditions effective for the Trichoderma strain to colonize the roots of the plant or a plant grown from the plant seed, thereby creating a plant-Trichoderma system. The plant or plant seed is grown under conditions effective to sustain the plant-Trichoderma system in a planting medium and to enhance plant growth, where the Trichoderma strain is selected from the group consisting of Trichoderma atroviride strain WW10TC4 (ATCC accession number PTA 9707), Trichoderma harzianum strain RR17Bc (ATCC accession number PTA 9708), Trichoderma harzianum strain F11Bab (ATCC accession number PTA 9709), and combinations thereof.

Abstract: The present invention relates to collagen hydrogels. Particularly, the invention relates to hydrogels comprising a telopeptide collagen (“telo-collagen”) and an atelopeptide collagen (“atelo-collagen”); hydrogels comprising collagen and chitosan; methods of making the hydrogels; methods of reducing gelation of a hydrogel mixture at room temperature; methods of reducing compaction of cells; and methods of culturing cells on such hydrogels.
Abstract: Identification of infectious pathogens, particularly viruses, bacteria and other microorganisms is effected with a method whereby pathogens of acute infections can be identified, without first culturing them in external nutrient media, by mass spectrometric measurement of their protein profiles obtained from pathogens directly precipitated from body fluid into pellets by centrifuging. With this method, pathogens which cause acute infections can be identified in less than one hour.
Abstract: A lactic acid component (e.g., lactic acid or oligo (lactic acid)) can be obtained by extraction from a lactic acid fermentation liquor with a pH of 4.8 or less, using at least one solvent selected from the group consisting of toluene, xylene, mesitylene, ethylbenzene, methanol, ethanol, propanol, butanol, and mineral spirit. Furthermore, oligo (lactic acid) can be obtained, by heating a lactic acid fermentation liquor with a pH of 4.8 or less under reduced pressure, and washing, with water, the fermentation liquor containing a produced oligo (lactic acid). Hence, a method is provided for separating a lactic acid component from a lactic acid fermentation liquor, which is free from incorporation of impurities and which includes simple steps.

Abstract: The present invention relates to a microplate, or microtitration plate, having an invagination consisting of a continuous peripheral channel making it possible to add thereto, in a single introduction step, a liquid acting as an “evaporation curtain”. The invention is also directed to a device comprising such a microplate, to a manufacturing method and to use of such a microplate.
Abstract: Embodiments described herein generally relate to systems and methods for promoting the expansion of high density non-adherent cells through the use of a cell growth chamber, a mass transfer device, and a fluid circulation loop. Improved cell growth is achieved in the cell growth chamber by using a chamber having a particular orientation and shape, e.g., conical, to create a media-rich reservoir for growing cells. By placing the chamber in a vertical position, the force of media flow along the chamber walls is substantially equal and opposite to the gravitational force on the cells. The interaction of these forces maintains the non-adherent cells in suspension. The use of the cell growth chamber in conjunction with the mass transfer device and fluid circulation loop(s) creates efficiencies by relying on the cumulative and combined features of the devices.
Abstract: Methods for culturing undifferentiated mammalian cells, such as stem and progenitor cells, are provided. The methods involve incubating the cell in the presence of a sustained release composition containing at least one growth factor, wherein the sustained release composition continuously releases the growth factor(s), and wherein the presence of the sustained level of growth factor maintains the cell in an undifferentiated state.
Abstract: A method of diagnosing a pathological condition by detecting microparticles in a sample of bodily fluid using dynamic light scattering (DLS) is disclosed.
