DETAILS

Description (English)
General description
α-Naphtylamine and sulfanilic acid are used for detection of nitrate reduction by bacteria. Organisms containing nitrate reductase reduce nitrate to nitrite, which forms a diazonium salt with sulfanilic acid and reacts with α-naphtylamine to form a red azo dye.
Description (简体中文)
General description
α-萘胺和磺胺酸用于检测细菌对硝酸盐的还原作用。含硝酸盐还原酶的生物体将硝酸盐还原为亚硝酸盐,亚硝酸盐与磺胺酸形成重氮盐,并与 α-萘胺反应形成红色偶氮染料。
