The uptake of iron by Listeria monocytogenes was studied. The microorganism was found to bind both 59Fe(II) and [59Fe3+]citrate. In contrast, L. monocytogenes was unable to acquire iron from [59Fe3+]ferroxamine or [59Fe3+]EDTA or as 59FeCl3. The data suggest that iron is acquired principally as iron(II) and that a citrate-inducible iron uptake system is also operative.
研究了单核细胞增生李斯特菌对铁的摄取。发现该微生物能结合59Fe(II)和[59Fe3+]柠檬酸盐。相比之下,单核细胞增生李斯特菌无法从[59Fe3+]去铁胺或[59Fe3+]乙二胺四乙酸中获取铁,也不能以59FeCl3的形式获取铁。数据表明,铁主要以亚铁形式被摄取,且一种柠檬酸盐诱导的铁摄取系统也起作用。
