NOVELTY - A Thaurea sp. strain T12 (CCTCC NO: M 2013477); and (GenBank (RTM: National institute of health (NIH) genetic sequence database) KF019186) capable of degrading triethylamine in wastewater, is new.    USE - The Thaurea sp. strain T12 is useful for degrading triethylamine in wastewater (all claimed).    ADVANTAGE - The Thaurea sp. strain has high degradation efficiency with respect to triethylamine present in high concentration in the wastewater, when compared to existing strains, and good adaptability, resistance properties and wastewater treatment application prospects.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) breeding method of the above-mentioned Thaurea sp., involves (a) adding 10 ml triethylamine cotnaining wastewater and 200 ml minimal salt medium (MSM) liquid culture medium to 500 ml conical flask, performing culturing process under shaking conditions at 150 revolutions per minute (rpm) and 30 degrees C for 6 hours, filtering cultured product, discarding precipitate, transferring filtrate as 5% inoculum into 100 mg/l MSM liquid culture medium, performing culturing process at 150 rpm and 30 degrees C for 48 hours, repeating the above-mentioned process until triethylamine is substantially removed, acclimatizing the medium for 7 days until concentration of the triethylamine in the wastewater reaches 100 mg/l, and again acclimatizing the medium for 4 days to obtain bacterial suspension, (b) diluting the bacterial suspension up to 10 times using sterilized water progressively up to 106-109 times, inoculating diluted bacterial suspension to MSM solid culture medium containing triethylamine as sole source of carbon and nitrogen, placing culture plate in inverted position inside the incubator, incubating the culture solution at 30 degrees C, observing growth of the bacteria during the culturing process, selecting single colony after 72 hours, scribing the solid culture medium containing 400 mg/l triethylamine, separating and purifying single colonies, repeating the above-mentioned process several times to obtain single colony and storing the single colony on slopes of culture slant, and (c) screening separated single colony, inoculating single colony into 400 mg/l triethylamine containing MSM culture medium, performing shaking culturing for 56 hours, measuring concentration of triethylamine change in the culture medium and selecting the culture medium containing single colony with significantly reduced triethylamine concentration; and (2) use of the Thaurea sp. for degrading triethylamine in wastewater.
