Quality control process for the dairy industry, useful e.g. for selecting cultures with optimal properties, comprises detecting gene sequences indicative of quality by nucleic acid hybridization

摘要

Quality control method for the dairy industry in which a sample is tested simultaneously for many genes (A) relevant for quality. A prepared sample is treated with many nucleotide probes (I), each specific for a particular (A), and the resulting hybridization products are detected. Independent claims are also included for the following: (1) method for investigating cultures for simultaneous presence of genes (B1) that mediate resistance to phages; (2) method for investigating cultures for presence of desirable genes (B2) that affect milk product properties (flavor; odor; consistency of the end product); (3) microarrays for performing the new methods; and (4) methods for targeted selection of a culture, or set of cultures, for milk processing.
