The authors studied ways of utilization of arginine and of the products of its metabolism (ornithine, agmatine, and urea) in the microoganisms of Citrobacter genus. Arginine- and ornithine-decarboxylase activity was revealed by spectrophotometric method of decarboxylation products in the form of dinitrophenyl-derivatives in a small number of strains. Almost all the strains studied demonstrated a sufficiently high agmatine-ureohydrolase reaction. Arginase was constantly revealed. These microbes were capable of urea utilization in prolonged incubation.
作者研究了柠檬酸杆菌属微生物中精氨酸及其代谢产物（鸟氨酸、胍丁胺和尿素）的利用方式。通过分光光度法测定少量菌株中以二硝基苯基衍生物形式存在的脱羧产物，揭示了精氨酸脱羧酶和鸟氨酸脱羧酶的活性。几乎所有研究的菌株都表现出足够高的胍丁胺尿素水解酶反应。精氨酸酶一直存在。这些微生物在长时间培养中能够利用尿素。
