摘要： An object is to provide an efficient treatment method for organic compounds using constitutive 1,4-dioxane-degrading bacterium strain N23. As a means for achieving the object, a biodegradation treatment method is provided, wherein organic compounds are biodegradation-treated with strain N23, which is a constitutive 1,4-dioxane-degrading bacterium deposited under Accession No. NITE BP-02032, under a condition of pH 3.0 or higher but no higher than 5.5.
