Abstract:
The present invention relates to a novel method for the rapid detection of the presence or absence of antimicrobial drug residues belonging to the class of the quinolones in liquid samples such as milk, meat juice, serum, urine, blood, eggs or extracts obtained from animal tissues or food products.
Abstract:
The present invention describes a composition comprising epsilon-poly-L-lysine and an anti-fungal agent. The composition has improved anti-microbial activity. Also covered are methods for preserving foodstuffs, agricultural products, adhesives, paints, inks, cosmetics and pharmaceutical products by applying the composition of the invention. The composition of the invention is stable and effective against a broad-spectrum of microbe.
Abstract:
The present invention describes a process to preserve a water-containing product such as a foodstuff, which comprises adding natamycin and nisin to the product, whereby at least 90% (w/v) of natamycin is dissolved and/or less than 10% (w/v) of natamycin is present in crystal form.
Abstract translation:本发明描述了一种保存含水产品如食品的方法,其包括将游霉素和乳链菌肽加入到产品中,由此至少90%(w / v)的游霉素溶解和/或少于10% w / v)的游霉素以晶体形式存在。
Abstract:
The present invention provides 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 component that binds to an antibiotic. Preferably the component that binds to an antibiotic is an antibody or a penicillin binding protein.
Abstract:
The present invention relates to a process to treat banana plants against disease wherein a polyene antibiotic is applied on the plant. In particular a process is described to protect banana crops from the devastating Sigatoka and Panama diseases. To that effect, banana plants are treated with a preparation comprising an amount of a polyene antibiotic effective to prevent or inhibit mould growth, especially M. fijensis and Fusarium oxysporum f sp. cubense.
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:
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.
Abstract:
Detection arrangement and method for detecting presence of a residue in a sample by determining color values of the sample, associated with the L*a*b color model, where a value of a composite parameter Z is calculated as follows: Z = w L + w a a + w b b where w L , w a , and w b are weighting factors having a value depending on said residue and said sample, and a determination is made whether or not said sample comprises more or less than a predetermined amount of said residue in dependence on said value of said composite parameter Z. In a preferred embodiment, the arrangement is used to detect antibiotic residues, e.g. penicillin-G, in food products, e.g. milk, or body fluids, e.g. blood, urine.
Abstract:
The present invention relates to a microbiological test method for detecting antibacterial compounds in liquid samples such as milk, meat juice, serum and urine. The method employs an acid-base or redox indicator to detect growth of a test organism and is characterised in that a thermophilic strain of Bacillus or Streptococcus, e.g. Bacillus stearothermophilus var. calidolactis C953, is employed at a concentration of above 10 CFU/ml, preferably between 2 x 10 and 3 x 10 CFU/ml.
Abstract:
The present invention provides a method of preparing an improved antifungal composition containing an antifungal compound of the polyene type such as natamycin wherein the antifungal compound is incorporated into the composition in a form which shows an enhanced activity, e.g. in the form of a solution and/or being in a modified polymorphic form.
