Abstract
Die Erfindung betrifft ein Faengersubstrat zur Sammlung luftgetragener Mikroorganismen mit einer Oberflaeche, die ganz oder zu wesentlichen Teilen aus feuchtigkeitsbindendem Glas und/oder einer solchen Glaskeramik besteht, wobei die Oberflaeche zum unspezifischen Sammeln der Mikroorganismen frei von Naehrstoffquellen sein oder zum selektiven Sammeln von Mikroorganismen Naehrstoffquellen aufweisen kann, die durch das Glas selbst oder durch Zusaetze bereitgestellt sein koennen. Das Faengersubstrat kann mittels geeigneter Zusaetze als Bioindikator fungieren.

 

DE 10051515 A UPAB: 20020701 NOVELTY - Capture substrate (A) for collecting airborne microorganisms has a surface made entirely, or at least mainly, of moisture-retaining glass and/or glass-ceramic, is new. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) bioindicator for qualitative or quantitative analysis of airborne microorganisms that includes (A); and (2) method for either integrative, non-specific or selective collection of airborne microorganisms using (A). USE - (A) is used in bioindicators for qualitative or quantitative analysis of airborne microorganisms (bacteria, viruses, fungi and yeast), either for non-specific (integrative) or selective collection, e.g. in hospitals or working/living environments. ADVANTAGE - (A) can be exposed to the environment for a long time without drying out (so that captured microorganisms remain viable and capable of characterization) and allows simple and reliable indication of air contamination. It is made from inexpensive materials; is simple to handle, requires no maintenance and is non-polluting; also since it is very small, it is inconspicuous.
