Biosynthesis of enzymes, catalyzing amino acid conversion in food products, and deposition of end products of protein metabolism is a current problem for hygiene-indicatory microorganisms. Results are reported of a study of decarboxylase and aminotransferase activities of a large number of Proteus strains. It was found that aminotransferases are produced by all members of this group of microorganisms, despite the specific differences in their quantitative characteristics. The composition of the different protein-containing food substrata exerts emphatic influence on the induction of these enzymes. The results of study of decarboxylase activity also point to some specific differences, applicable in the differential diagnosis. The inferences summarize the importance of the whole Proteus group as hygiene-indicatory microorganisms, producing enzymes of essential importance for the quality and biologic value of food products.
催化食品中氨基酸转化的酶的生物合成以及蛋白质代谢终产物的沉积是卫生指示微生物面临的一个当前问题。本文报道了对大量变形杆菌菌株的脱羧酶和转氨酶活性的研究结果。结果发现，尽管该组微生物在数量特征上存在特定差异，但所有成员均能产生转氨酶。不同含蛋白质食物底物的组成对这些酶的诱导有显著影响。脱羧酶活性的研究结果也表明了一些适用于鉴别诊断的特定差异。这些推论总结了整个变形杆菌属作为卫生指示微生物的重要性，它们产生的酶对食品质量和生物学价值至关重要。
