Abstract
Cells of Escherichia coli will reduce sodium selenite to elemental selenium. Examination by electron microscopy of E. coli cultures grown in the presence of sodium selenite show selenium deposited on the cell membrane and cell wall but not in the cytoplasm.
摘要
大肠杆菌细胞会将亚硒酸钠还原为元素硒。对在亚硒酸钠存在下生长的大肠杆菌培养物进行电子显微镜检查发现，硒沉积在细胞膜和细胞壁上，而不是细胞质中。
