Percent G+C profiling accurately reveals diet-related differences in the gastrointestinal microbial community of broiler chickens.

abstract：:The killing of Listeria monocytogenes following exposure to low pH, organic acids, and osmotic stress was enhanced by the addition of 5% (vol/vol) ethanol. At pH 3, for example, the presence of this agent stimulated killing by more than 3 log units in 40 min of exposure. The rate of cell death at pH 3.0 was dependent ...
