摘 要: 研究筛选一株具有玉米赤霉烯酮(zearalenone,ZEA)转化降解能力的不动杆菌P5,发现该菌株发酵72 h后,可降解98%的ZEA. 经过培养基成分初步探索,发现以乙酸钠和硝酸铵分别作为无机碳源和氮源的培养基有利于该菌株彻底高效地降解ZEA,且不会生成α-玉米赤霉烯醇(α-zearalenol,ZOL)等次级有毒代谢物。
关 键 词: 食品检验学;玉米赤霉烯酮;有效降解;不动杆菌;高效液相色谱

Abstract: This research identified an Acinetobacter sp. P5 which could degradate zearalenone (ZEA) and found that 98% of ZEA could be degradated after fementating for 72 h. Based on the preliminary exploration of medium components, it was found that it was beneficial for this strain to degrade ZEA thoroughly and efficiently by the application of sodium acetate and ammonium nitrate as the inorganic carbon source and the nitrogen source of the medium, and this degradation did not generate secondary mycotoxic metobolite such as α-zearalenol (ZOL).
Key words: food inspection; zearalenone; effective degradation; Acinetobacter; high performance liquid chromatography
