  • Patent number: 9605256
    Abstract: 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.

  • Patent number: 9555403
    Abstract: A process for activating a hydroalkylation catalyst in a first state comprising an acid component and a hydrogenating metal component, including: (i) treatment at a temperature of at least 120° C. in the presence of hydrogen for a first duration to produce a catalyst in a second state having a first hydroalkylation activity; (ii) contacting the catalyst in the second state with an aromatic compound and hydrogen under a hydroalkylation condition effective to convert at least part of the aromatic compound to a cycloalkylaromatic compound and produce a catalyst in a third state; and (iii) treating the catalyst in the third state at a temperature of at least 160° C. in the presence of hydrogen but advantageously in the substantial absence of the aromatic compound for a third duration to produce an activated catalyst in a fourth state having a third hydroalkylation activity greater than the first hydroalkylation activity.
