摘要

PROBLEM TO BE SOLVED: To provide novel activated sludge excellent in 1,4-dioxane degrading ability.SOLUTION: The invention provides an activated sludge comprising at least one microorganism selected from 1,4-dioxane degrading microorganisms A, B and C, where the 16S rRNA gene of microorganism A has 97% or more identity to the base sequence of SEQ ID NO: 1, the 16S rRNA gene of microorganism B has 97% or more identity to the base sequence of SEQ ID NO: 2, and the 16S rRNA gene of microorganism C has 97% or more identity to the base sequence of SEQ ID NO: 3.SELECTED DRAWING: None
