摘要: 为建立VBNC状态沙门氏菌实验室快速诱导条件,以4 ℃低温诱导为对照组,在此基础上,添加不同浓度Cu2+和冰醋酸作为快速诱导条件进行试验。结果表明,在4 ℃低温条件下,添加2~4 mM Cu2+对沙门氏菌进入VBNC状态有明显促进作用,与传统诱导条件相比,诱导时间平均提前15 d。对诱导进入VBNC状态的沙门氏菌进行16S rRNA鉴定,结果证明,所得菌为VBNC状态沙门氏菌。

Abstract: In order to establish the rapid induction condition of VBNC state Salmonella pulorum, the induction at the low temperature of 4 ℃ was selected as the control group, and on this basis, the experiment was conducted through adding different concentrations of Cu2+ and glacial acetic acid as the rapid induction condition. The results show that adding 2~4 mM Cu2+ could obviously promote Salmonella into VBNC state at 4 ℃ low temperature, and compared with the traditional induction condition, the induction time could be advanced 15 d averagely. The Salmonella entering into the VBNC state was identified by 16S rRNA test, and the results proved that the stains were Salmonella of VBNC state.

Key words: viable but non-culturable state, Salmonella, 16S rRNA, Cu2+
