摘要/Abstract

摘要： 从南大西洋深海海水中分离到一株放线菌菌株R104，该菌株的发酵无细胞上清液对黄曲霉毒素合成的抑制率高达96.2%，经16S rDNA序列分析，初步将该菌株鉴定为微杆菌（Microbacterium），这是首次报道深海来源的微杆菌具有抑制黄曲霉毒素合成的能力。

关键词: 深海, 微杆菌, 黄曲霉毒素

Abstract: An actinobacterial strain R104 was isolated from deep-sea water of the South Atlantic. After fermentation，the cell-free supernatant of strain R104 showed strong inhibition activity against aflatoxin producing with an inhibition ratio of 96.2%. This strain was identified as Microbacterium by 16S rDNA sequence analysis. To the best of our knowledge，this was the first report that Microbacterium from deep-sea was capable of inhibiting aflatoxin production.

Key words: deep-sea, Microbacterium, aflatoxin
