Abstract

Euglena gracilis strain Z, green, dark-brown, and "bleached" with N-methyl-N-nitro-N-nitrosoguanidine, was found to contain 2 soluble enzymes which reduce nitrofurans. A small amount of activity was demonstrated also in a particulate fraction of sonic extracts, but none in isolated chloroplasts. The reduction of 5 nitrofurans, having widely differing bleaching activities, by each of the 2 enzymes was examined.

摘要

纤细裸藻Z株，绿色、深棕色以及用N-甲基-N-硝基-N-亚硝基胍“漂白”的菌株，被发现含有两种可还原硝基呋喃的可溶性酶。在超声提取物的颗粒部分也显示出少量活性，但在分离的叶绿体中没有活性。研究了这两种酶对5种具有广泛不同漂白活性的硝基呋喃的还原作用。
