Abstract

The results are given of the ortho-nitrophenol test for beta-galactosidase production (ONPG test) on 588 strains of 123 aerobic species of bacteria, representing 30 genera. Apart from some strains of Erwinia herbicola (synonym Chromobacterium typhiflavum) and of Yersinia spp, these strains were not members of the Enterobacteriaceae, in which family the ONPG test is widely used and well documented. The strains were also tested for acid production from 1, 5, and 10% lactose and the findings are discussed in relation to the ONPG test.

摘要

给出了对代表30个属的123个需氧菌种的588株细菌进行β-半乳糖苷酶产生的邻硝基苯酚试验(ONPG试验)的结果。除了一些草生欧文氏菌(同义词:淡黄杆菌)和耶尔森氏菌属的菌株外,这些菌株不是肠杆菌科的成员,而在肠杆菌科中ONPG试验被广泛使用且有充分记录。还对这些菌株进行了从1%、5%和10%乳糖产酸的测试,并结合ONPG试验对结果进行了讨论。
