1.To prepare the Listeria Enrichment Broth,add 0.90ml of nalidixic acid solution and 0.34ml acriflavine HCI solution to 225ml of the base medium.

使用前225ml培养基中加入萘啶酮酸溶液0.90ml和吖啶黄溶液0.34ml可制成EB增菌液。

2.Listeria species in environmental samples from the food plant were detected by 3M Petrifilm by identifying the 210 typical colonies and 70 nontypical colonies from 112 environmental samples.

摘要共采集112环境样本，挑取了210典菌落，70非典菌落进行鉴定，评估3M测试片对食品加工环境中李特菌的检测能力。
