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:
A substrate for mushroom cultivation comprises a polyene fungicide, in particular natamycin. Mushrooms cultivated in such substrates can be harvested earlier than mushrooms cultivated in substrates which do not include polyene fungicides. Alternatively, mushrooms grown in a substrate comprising a polyene fungicide achieve a greater size than mushrooms grown for the same amount of time in a substrate which does not include a polyene fungicide.
