Abstract: L. monocytogenes was incubated into non-selective enrichment broth TSBYE and selective enrichment broth UVM-LEB, DFB and FB with different temperatures. Comparing the growth curve, the highest growth temperature and the bestgrowth amount in TSBYE, UVM-LEB, DFB and FB were obtained. The growth of L. monocytogenes was evidently inhibitedby the selective media and the inhibition of FB was better than UVM-LEB and DFB,while the inhibition of DFB almost equaledto UVM-LEB. The lowest measurable concentrations of L. monocytogenes in UVM-LEB, DFB and FB were 5.2/ml 、52/mland 5200/ml respectively after 24 hours incubation,and 0.52/ml、0.052/ml and 0.52/ml respectively after 48 hours incubation.As selective enrichment broth, DFB and FB were better than UVM-LEB.

Key words: Listeria monocytogenes, selective enrichment broth, non-selective enrichment broth
