Abstract
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.
Claims10
A biodegradation treatment method comprising biodegradation-treating at least one organic compound, to reduce concentration thereof, with strain N23, which is a constitutive 1,4-dioxane-degrading bacterium deposited under Accession No. NITE BP-02032, under a condition of pH 3.8 or higher but no higher than 5.5, which is lower than an optimal pH for 1,4-dioxane degradation activity and growth of the bacterium, while maintaining 80% or greater of degradation activity at pH 7.0 and maintaining the capability of growth,
- wherein the organic compound is selected from the group consisting of cyclic ethers, ethylene glycol, diethylene glycol, 1,4-butanediol, and combinations thereof.
