pyruvate oxidase with high thermal stability, this verwendendes analytical procedures and those containing analytical reagents.

摘要

A pyruvate oxidase having high thermal stability, being stable at a pH of 7.0 for 10 minutes at a temperature of up to 45 DEG C, can be obtained by culturing a strain of bacteria of the genus Lactobacillus which has pyruvate oxidase activity, such as Lactobacillus sp. TE-6103 (FERM BP-1419). This pyruvate oxidase can be used in analytical methods requiring such an enzyme, for which purpose it can form part of an analytical reagent for use in such a method.
