Identification of Corynebacterium amycolatum and Other Nonlipophilic Fermentative Corynebacteria of Human Origin

摘要

Four identification tests, proposed in addition to conventional methods, were evaluated with 320 fermentative nonlipophilicCorynebacterium strains: growth at 20°C, glucose fermentation at 42°C, alkalinization of sodium formate, and acid production from ethylene glycol. These tests were highly discriminant.Corynebacterium amycolatum displayed a unique profile, allowing it to be distinguished from similar species, such as C. xerosis, C. striatum, and C. minutissimum.
