Abstract:
Provided is a test system, a test method and a test kit for the determination of the presence of an antibiotic in a fluid based on a test medium comprising a test organism, at least one substance that provides a solid state, nutrients and an indicator, wherein the end-pH of said test medium at or after the time required for said determination is equal to or higher than 7.2 Said pH value can be realized by adding oligosaccharides, preferably a disaccharide or trisaccharide (eg. Lactose, gentobiose, maltotriose). Most preferably, said oligosaccharide is a non-reducing oligosaccharide (eg. Raffinose, sucrose or trehalose). .
Abstract:
The present invention relates to the treatment of banana and potato plants with a composition containing natamycin and at least one phosphite containing compound.
Abstract:
The present invention relates to a novel method for the rapid detection of the presence or absence of antimicrobial residues in eggs. A one step test method is described in which residues of antimicrobial compounds such as antibiotics are detected while inhibiting compounds naturally present in samples obtained from eggs, which may interfere with the test, are inactivated.
Abstract:
The present invention provides a test medium comprising a test microorganism, an indicator and a metal in ionized form, wherein the valence of said metal is at least 2 and the concentration of said metal is between 0.001 M and 1 M. Furthermore, there is provided a method for the determination of the presence of an antibiotic characterized in that a metal salt is added to said test medium and/or to said sample of fluid. Finally, there is provided a kit suitable for the determination of an antibiotic in a fluid.
Abstract:
The present invention relates to a novel method for the rapid detection of the presence or absence of antimicrobial residues in products preferably food products.
Abstract:
Provided is a test system, a test method and a test kit based on a test medium comprising Bromothymol Blue or a structurally related indicator.
