在弗里克塞尔湖中紫色非硫细菌典型的多功能性，在暗反应方面来说Madigan 1988 1998可能因此比紫色硫细菌在生理方面更有利。
The typical versatility of purple non-sulfur bacteria in terms of dark metabolism (Madigan 1988, 1998) may thus favor this physiological group over purple sulfur bacteria in Lake Fryxell.
本文基于维生素K_3（亚硫酸氢钠甲萘醌）或甲萘醌在碱性介质中与氨基硫脲生成紫色化合物的反应。
The method was based on the reaction of the vitamin K_3 (menadione sodium bisulfite) or menadione with thiosemicarbazide to form an violet compound in alkaline medium.
以NBT/BCIP为酶反应显色底物观察到在细胞周围形成许多暗紫色颗粒，证实病毒与细胞间存在着稳定的结合。
Using an NBT/BCIP color detection system, dark purple grains were seen around cells by light microscopy and indicated stable binding between DIG-WSSV and hemocytes.
在碳酸钾中，它变成黑色，而在明矾中一开始却什么反应都没有，直到煮沸后紫色都溢出来了。
In potash it turns black, but in alum nothing happens until you bring it to the boil, then purple colour comes flooding out.
