Isolation and identification of catalase-producing strain CE-1
产过氧化氢酶菌株CE-1 的筛选与鉴定

Catalase-producing strain CE-1 was isolated from water samples using H2O2-containing plate screening and activity assay of the shake flask culture method. The values of the activity and specific activity were 1356.2 U/mL and 3401U/mg, respectively. CE-1 was Gram negative and rod in shape. Based on the comprehensive analysis of morphological and physiological characteristics, the 16S rDNA phylogenetic tree, and the differences among different species of Aeromonas, strain CE-1 was identified to be Aeromonas.
