摘要：

Homogenization by blending or stomaching was compared for the recovery of Listeria monocytogenes from inoculated intact beef tissue. There were no differences in numbers of recovered bacteria (P>0.10) attributable to either homogenization time or method. Fewer viable bacteria (P<0.05) were recovered in phosphate buffer than either buffered peptone water or 2% trisodium citrate buffer. Tween 80 increased the numbers of bacteria recovered from fat tissue (P<0.05). Stomaching is an acceptable method for homogenizing samples for Listeria analysis. Copyright © 1990, Wiley Blackwell.
