Abstract
- A micro-organism similar to Arthrobacter globiformis has been isolated from sewage by elective growth on a medium containing l-threonine as sole source of carbon and nitrogen. 2. Washed cell suspensions of the organism catalyse the complete disappearance of aminoacetone from the medium and its almost complete oxidation. 3. In the presence of iodoacetate, aminoacetone disappearance is accompanied by the accumulation of methylglyoxal, about 70% of the aminoacetone removed being accounted for in this way. 4. It is suggested that the conversion of aminoacetone into methylglyoxal is catalysed by an amine oxidase.
摘要
- 已从污水中分离出一种类似于球形节杆菌的微生物，该微生物在以L-苏氨酸作为唯一碳源和氮源的培养基上通过选择性生长而获得。2. 该微生物的洗涤细胞悬液能催化培养基中氨基丙酮完全消失并几乎将其完全氧化。3. 在碘乙酸存在的情况下，氨基丙酮消失的同时伴有甲基乙二醛的积累，以这种方式约70%被去除的氨基丙酮可得到解释。4. 有人提出，氨基丙酮向甲基乙二醛的转化是由一种胺氧化酶催化的。
