Patent number: 9605256Abstract: Procedure for the specific isolation of total DNA content of bacterial germs of different samples, in the course of which the cells are lysated, the DNA content of the lysate is bound selectively, it is washed and then the desalinated linear polymer nucleic acid is eluted from the binding surface in an aqueous solution. Before cell lysis the nonviable bacterial cells are separated from the viable cells on the basis of their different cell surface physical-chemical characteristics, the viable cells of the sample are kept and then lysated using a mechanical and/or enzymatic, favorably lysozyme enzymatic method. After this exclusively double-stranded DNA deriving from the lysate of viable cells is bound on a —SiO2—TiO2— matrix containing chemically activated —OH and dodecylamine groups, and after washing it, the desalinated linear polymer nucleic acid is eluted in an aqueous solution.Type: GrantFiled: May 5, 2015Date of Patent: March 28, 2017Assignee: Diagon Ltd.Inventors: Gabor Kiss, Janos Kiss, Katalin Sztancsik Ambrusne Kovacs, Georgina Bernath

Publication number: 20130324436Abstract: Disclosed are procedures and kits for nucleic acid-based molecular diagnostic determination of bacterial germ counts during which procedure evolutionarily conserved genes and genes coding for characteristic pathogenicity markers, favourably microbial enzyme, toxin, special resistance, are detected using real-time PCR amplification method with the application of fluorescent hydrolysis probes. The multiplication of nucleotide chains takes place with oligonucleotides annealing to the structural gene 5? end region and to the adjacent upstream regulatory promoter-operator region so that the presence of the structural gene is shown along with the adjacent upstream regulatory promoter-operator sequences; the functional nature of the structural gene is simultaneously checked. The result is measured with a genome unit equivalent DNA amount calibrated to the germ number of sample units equivalent to standard procedures.Type: ApplicationFiled: November 30, 2010Publication date: December 5, 2013Applicant: DIAGON KFTInventors: Gabor Kiss, Janos Kiss, Timea Kiss, Ambrusne Sztancsik Katalin Kovacs, Georgina Bernath

Patent number: 3979259Abstract: The invention relates to a process for the production of a fermentation broth with increased vitamin B.sub.12 content by a fermentation process carried out with a methane-producing mixed bacterium population under anaerobic septic conditions in the presence of known nutrient components and precursors.
