摘要
在强酸性介质(70% HClO4)中，链霉素形成荧光团(λ ex = 312 nm;λ em = 381 nm)，结构未知。根据这一反应，分别对纯产物或粗产物和培养物进行了荧光测定。荧光测量的浓度范围为10(-8)- 2 X 10(-7)摩尔。讨论了测定的干扰，对结果进行了统计评价，并对微生物学和荧光学结果进行了比较。
In strongly acidic medium (70% HClO4) streptothricins form a fluorophore (lambda ex = 312 nm; lambda em = 381 nm) with unknown structure. A fluorimetric determination of pure or crude products and cultures, respectively, was worked out based on this reaction. Concentrations for fluorescence measurements were in the range of 10(-8) - 2 X 10(-7) moles. Interferences of the assay are discussed, a statistical evaluation of results and a comparison between microbiological and fluorimetric findings are given.
