Abstract
Ethers including dioxanes are degraded by bringing an ether-containing influent into intimate contact, under growth or resting conditions and in the presence of oxygen, with a culture comprising a bacterium having the characterizing microbiological properties of Amycolata ATCC 55486 or a mutant thereof which retains the characterizing microbiological property of being capable of utilizing dioxane as a sole carbon growth source.
Claims10
A process for the degradation of ethers which comprises bringing an ether-containing liquid influent into intimate contact, with a culture comprising an actinomycete, genus Amycolata, having all identifying characteristics of ATCC 55486, or a mutant thereof which retains the characterizing microbiological property of being capable of utilizing dioxane as a sole carbon growth source, in the presence of oxygen, and under growth or resting conditions permitting said actinomycete or said mutant thereof to utilize the ether as a carbon source, thereby degrading said ether.
A process for the degradation of dioxanes which comprises bringing a dioxane-containing liquid influent into intimate contact, in the presence of oxygen, at a temperature of from about 10.degree. C. to about 42.degree. C., and at a pH of from about 5 to about 8, with a culture comprising an actinomycete, genus Amycolata, ATCC 55486 or a mutant thereof which retains the characterizing microbiological property of the parent microorganism of being capable of utilizing dioxane as a sole carbon source, and under suitable conditions permitting said actinomycete or said mutant thereof to utilize the dioxane as a carbon source, thereby degrading said dioxane.
A biologically pure culture of Amycolata ATCC 55486, or a mutant thereof possessing the capability of the parent microorganism of using dioxane as a sole carbon source.
