Abstract

Aeromonas sp. will methylate trimethyl lead acetate (Me3PbOAc) to volatile tetramethyl lead (Me4Pb). Examination of cultures grown in the presence of Me3PbOAc revealed no major irregularities between cells of the treated and untreated cultures. Some cells, however, showed evidence that intracytoplasmic materials had been leached from the cells. The lead-treated cells were interpreted to contain lead ions on the basis of energy-dispersive X-ray analysis.

摘要

气单胞菌属细菌会将醋酸三甲基铅（Me3PbOAc）甲基化生成挥发性的四甲基铅（Me4Pb）。对在醋酸三甲基铅存在下培养的菌进行检查发现，处理过的培养物和未处理的培养物中的细胞之间没有重大异常。然而，一些细胞显示出有胞质物质从细胞中渗出的迹象。根据能量色散X射线分析，经铅处理的细胞被认为含有铅离子。
