Freeze-Drying Method of Salmonella enterica subsp. enterica TA1535/pSK1002

摘要

The present invention is used in the SOS genotoxicity detection / umu -test strains relates to a freeze-drying method. More specifically, the method of the present invention includes the steps of: (a) Salmonella Entebbe Rica ( Salmonella enterica ) culturing TA1535 / pSK1002 strain; (B) adding at least one preservative selected from the group consisting of frozen sucrose and trehalose to glucose, trehalose in strains cultured in said step (a); (C) freeze-drying the frozen preservative added strain in said step (b). According to the freeze-drying method for detecting genotoxicity strain of the present invention, can be stored for a long time, and the color-developing performance and retention, by providing a freeze-dried strains with improved survival rate, speed and ease of use is improved kit for the detection of genotoxicity (kit) can be very useful to take advantage of the production.
