Publication number: 20080118580Abstract: The invention relates to the use of substances that influence fungal dimorphism for reducing the adhesion of fungi to surfaces. The invention also relates to washing and/or cleaning agents, textile treating agents and cleaning agents for mouth, teeth or dentures and to the use of said substances in said agents. The inventive substances are selected from propolis extracts, plant extracts, cinnamic acid and the derivatives thereof, monoterpenes, sesquiterpenes and diterpenes and the derivatives thereof, especially fucoidine, anethol, geraniol, farnesol or farnesol acid.Type: ApplicationFiled: December 3, 2007Publication date: May 22, 2008Inventors: Dirk Bockmuhl, Roland Breves, Mirko Weide, Stefan Stumpe, Michael Heinzel

Publication number: 20080003610Abstract: The invention relates to a method for quantitatively and/or qualitatively identifying germs in a sample, which method comprises a step (a) of preparing the sample by labeling at least some of the germs present in the sample by means of at least one fluorescent marker and a step (b) involving a quantitative and/or qualitative detection and/or evaluation by recording and/or measuring fluorescence emission, wherein, in step (b), the sample containing the fluorescently labeled germs, prepared in step (a), is subjected to an excitation radiation of a defined wavelength or a defined wavelength range for a defined period of time, and the time course of the fluorescence emission radiation generated due to said excitation is recorded, so that a discrimination first, between the measured signals caused by the fluorescently labeled germs, second, possible interfering signals is made possible, thereby identifying the fluorescently labeled germs in the sample in a quantitative and/or qualitative manner.Type: ApplicationFiled: August 8, 2007Publication date: January 3, 2008Inventors: Michael FRANK, Helmut HERRMANN, Friedhelm SIEPMANN, Stefan STUMPE, Andreas THUNCHEN

Publication number: 20060024710Abstract: A method for quantitative and/or qualitative determination of germs in a liquid sample comprises the steps of: (1) passing the sample through a filter thereby depositing the germs on a major portion of the filter so that a minor portion of the filter is free of germ deposits; (2) applying a fluorescent label to at least a portion of the deposited germs; (3) determining the presence and/or the amount of labeled germs by fluorescent reflection photometry. The method according to the present invention is suitable, for example, for quantitative and/or qualitative determination of germs in foodstuffs, surfactant-containing products such as washing and cleaning agents, surface treatment agents, dispersion products, cosmetics, hygiene products and personal care products, pharmaceuticals, adhesives, coolant lubricants, coatings and coating coagulations, as well as raw materials and starting materials for the aforesaid products.Type: ApplicationFiled: June 16, 2005Publication date: February 2, 2006Inventors: Tilo Weiss, Stefan Stumpe, Friedhelm Siepmann, Andreas Thuenchen, Frank Wienhausen, Andreas Katerkamp, Michael Heinzel, Roland Breves, Mirko Weide
