Clostridium sporogenes was found to have an absolute requirement for selenium to utilize glycine but not proline as oxidant in Stickland-type fermentations. No glycine reductase activity was detectable in cells from media without added selenium. The data indicate that this organism could be used for microbiological assays for very low levels of selenium in certain forms.
已发现生孢梭菌在Stickland型发酵中利用甘氨酸作为氧化剂时对硒有绝对需求,但利用脯氨酸作为氧化剂时则不然。在未添加硒的培养基中的细胞中未检测到甘氨酸还原酶活性。数据表明,这种微生物可用于某些形式的极低水平硒的微生物学测定。
