20080268524 | Method of Modifying the Viability of a Lyophilized Microorganism by Treating the Growth Medium Thereof with Gases - The invention relates to a method of producing lyophilized microorganisms, such as lyophilized bacteria, of the type in which a culture medium is inoculated with one or more strains of microorganisms during one of the steps of the method. The invention is characterised in that, prior to the inoculation step, the culture medium is treated with a treatment gas comprising an inert gas or a reducing gas or a mixture of such inert and reducing gases, in order to obtain a determined redox potential value Eh for the medium, which is less than the value obtained when the medium is in equilibrium with the air. | 10-30-2008 |
20090053798 | Method of Improving Storage Stability of Dried Microorganisms - The present invention relates to a method of improving storage stability of dried microorganisms, such as dried lactic acid bacteria, by allowing the dried microorganisms to coexist with an L-arginine acidic amino acid salt, a composition comprising dried microorganisms and an L-arginine acidic amino acid salt and a process for producing the same, and a method of storing dried microorganisms in the presence of an L-arginine acidic amino acid salt. The storage stability of dried microorganisms can be improved by allowing the dried microorganisms to coexist with an L-arginine acidic amino acid salt. | 02-26-2009 |
20090123992 | Shape-Shifting Vitrification Device - This invention is a storage device (cryocontainer) for the vitrification method of cryopreservation that uses shape memory materials to create a novel shape-shifting feature in which the relevant heat transfer zone of the cryocontainer can be thermally morphed between a shape conducive to biological specimen handling and to a shape conducive to rapid heat transfer. This feature utilizes the temperature induced phase transformation of shape memory materials. The temperature inducement occurs naturally within the normal temperature changes that occur during vitrification. | 05-14-2009 |
20100196996 | Process For Preserving Biological Materials For Extended Periods Of Time - The present invention provides for a process for preserving biological material. The process comprises subjecting the biological material to a fixation process and then packaging the biological material in a container under a controlled atmosphere of noble gas. In the process, the controlled atmosphere of noble gas utilized comprises one or more noble gases selected from argon, xenon, helium, neon, krypton and radon. The process optionally also utilizes one or more additional gases selected from nitric oxide, hydrogen, hydrogen sulfide, carbon monoxide, carbon dioxide, nitrogen and oxygen. This process allows for the long term storage of the biological material. | 08-05-2010 |
20110027868 | APPARATUS AND METHOD FOR DEHYDRATING BIOLOGICAL MATERIALS - An apparatus for dehydrating a liquid sample of biological material has a microwave waveguide that is open to the atmosphere. It has a microwave generator, means for introducing a container of the material into the waveguide, means for evacuating the container, means for rotating the container and means for removing the container from the waveguide. It can include means for moving the container through the waveguide and for sealing it. In a dehydration method, a container of the liquid sample is put into the open waveguide, evacuated, rotated at high speed and microwaved. The container of dehydrated material is then removed from the waveguide. The apparatus and method are particularly suitable for dehydrating vaccines. | 02-03-2011 |
20160053219 | SYSTEMS, METHODS, AND DEVICES FOR TEMPERATURE CONTROL - Systems, methods, and devices are disclosed for improved temperature control, particularly within a predetermined range of temperatures near or above varying ambient temperatures. Previously-unrealized advantages are recognized for maintaining samples, particularly medical and/or biological specimens, at a temperature within a predetermined range of temperatures near or above ambient temperature that selectively promote and/or selectively inhibit organism growth, organism viability, biochemical reactions, and/or chemical reactions. Systems, methods, and devices may include at least phase change material selected and configured to maintain a sample at a predetermined temperature range between about 22° Celsius and about 100° Celsius during a predetermined time period. | 02-25-2016 |
