Abstract
A biological degradation process is disclosed. The biological gradation process utilizes a unique thermophilic aerobic bacterial mixture capable of converting, biologically or via oxidation, aqueous and other liquid streams containing substances that are ordinarily considered toxic to conventional biological systems. Substances ordinarily considered toxic to conventional biological systems, but which nevertheless are converted by the thermophilic aerobic bacterial mixture, include aniline; benzothiazole; 5,6-dihydro-2-methyl-N-phenyl-1,4-oxathiin-3-carboxamide; lindane (technically known as 1.alpha.,2.alpha.,3.beta.,4.alpha.,5.alpha.,6.beta.-hexachlorocyclohexane) ; 2-mercaptobenzothiazole; toluene; and combinations thereof. The unique thermophilic aerobic bacterial mixture comprises relative effective amounts of Pseudomonas stutzeri, Pseudomonas aeruginosa, Pseudomonas fluorescens, Pseudomonas mendocina and Alcaligenes denitrificans subsp. xylosoxydans. A biological degradation process for treating the liquid stream containing substances ordinarily considered toxic comprises contacting the stream with the thermophilic aerobic bacterial mixture, for an amount of time that is effective for de-toxifying the stream.
