Patent number: 7824882Abstract: 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).Type: GrantFiled: June 2, 2005Date of Patent: November 2, 2010Assignee: DSM IP Assets B.V.Inventors: Pieter Cornelis Langeveld, Johannes Theodorus Arie van Pelt, Jacobus Stark, Tim de Graaf

Patent number: 7736588Abstract: Detection arrangement and method for detecting presence of a residue in a sample include determining color values of the sample, associated with the L*a*b color model. A value of a composite parameter Z is calculated as follows: A=wL+waa+wbb where wL, wa and wb are weighting factors having a value depending on the residue and the sample. A determination is made whether or not the sample comprises more or less than a predetermined amount of the residue in dependence on the value of the composition parameter Z. In a preferred embodiment, the arrangement is used to detect antibiotic residues, e.g. penicillin-G, in food products, elg. Milk, or body fluids, e.g. blood, urine.Type: GrantFiled: October 10, 2002Date of Patent: June 15, 2010Assignee: DSM IP Assets B.V.Inventors: Pieter Cornelis Langeveld, Karl Heinrich Van Hemert, Johannes Hendrik Pieter Machiel Kerkhof, Jacobus Stark
