Publication number: 20150376601Abstract: 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: ApplicationFiled: May 5, 2015Publication date: December 31, 2015Inventors: Gabor Kiss, Janos Kiss, Katalin Sztancsik Ambrusne Kovacs, Georgina Bernath

Patent number: 9169170Abstract: An alkylating process such as hydroalkylating process comprising feeding a gas material and a liquid material into the reactor, distributing the liquid material to the upper surface of a bed of a catalyst substantially uniformly. The substantial uniform distribution of the liquid material to the upper surface allows for substantially uniform distribution of liquid reaction medium in the bed, thereby preventing hot spot and undesirable continuous liquid zone, both of which can cause the production of undesired by-products. The invention is particularly useful for the hydroalkylation reaction of benzene in making cyclohexylbenzene, which can be used for making cyclohexanone and phenol.Type: GrantFiled: September 4, 2014Date of Patent: October 27, 2015Assignee: ExxonMobil Chemical Patents Inc.Inventors: Gabor Kiss, Keith H. Kuechler
