The metal complex, in particular ammonium ferric citrate, contains a concentration ranging between 0.3 and 0.9 mg/ml, ... 06/23/05 - 20050136508 - Method and apparatus for detecting and quantifying bacterial spores on a surface A method and an apparatus for detecting and quantifying bacterial spores on a surface. In accordance with the method: a matrix including lanthanide ions is provided on the surface containing the bacterial spores; functionalized aromatic molecules are released from the bacterial spores on the surface; a complex of the lanthanide ... 06/16/05 - 20050130256 - Isolation and cultivation of microorganisms from natural environments and drug discovery based thereon The method of the invention is directed to the novel use of a diffusion chamber within which previously “uncultivatible” microorganisms can be isolated. Rather than attempting to replicate the natural environment of an unknown microorganism, the method of the invention provides for exposing dividing microorganisms to all the components of ... 06/16/05 - 20050130255 - Process control based on microbiological activity The present invention relates to the determination of environmental conditions for the purpose of process control using microorganisms. The present invention uses the priciple that intrinsic changes in a microorganism after applying an external stimulus are characteristic of the nature of the stimulus the microorganism receives from outside. By measuring ... 06/09/05 - 20050124027 - Method for recovering microorganisms from a sample The present invention provides for a method for recovering microorganisms from a sample which is rapid and provides microorganisms substantially free of adsorbents and other particles. The method comprises the steps of: (a) mixing a sample comprising a medium, an adsorbent and microorganisms with a first solution in a first ... 06/09/05 - 20050124026 - Methods for detecting bacterial pathogens (d) detecting Staphylococcus aureus in the resulting suspension of step (c) by using an agglutination test. ... ### FreshPatents.com Support |
