Sensitization of Listeria monocytogenes to low pH, organic acids, and osmotic stress by ethanol.

abstract：:A new method for the extraction of bacterial DNA from soil has been developed. Soil samples of 50 g were dispersed, and bacteria were released by use of a cation-exchange resin; subsequently, bacteria were separated from soil particles by low-speed centrifugation and lysed with lysozyme and ionic detergent, and the DN...
