Embodiment Construction

[0023] The present invention relates to a strain of Acinetobacter sp.T1, which is classified as Acinetobacter sp.T1, and has been preserved in the China Center for Type Culture Collection (CCTCC) on November 9, 2014, with the preservation number CCTCC NO. M 2014558, deposit address: Wuhan University, Wuhan, China.

[0024] The above-mentioned Acinetobacter has the following characteristics: the colony is white, round, with neat edges, smooth surface and moist. Microscopically observed as rod-shaped, no spores, no flagella, Gram-negative.

[0025] The above-mentioned Acinetobacter strain can be used to degrade terephthalic acid, a specific pollutant in printing and dyeing wastewater. One of the degradation methods is: the inoculation amount is 1%, the temperature is 20-40°C, the pH is 6-8, and the printing and dyeing wastewater ( The concentration of terephthalic acid is 100-1000mg / L), the rotation speed of the shaker is 150-200r / min, and the degradation efficiency is detected...

Abstract

The invention relates to acinetobacter which is classified to be Acinetobacter sp.T1 and is collected with the number of China center for type culture collection (CCTCC) NO.M2014558 in CCTCC on November 9th, 2014. The acinetobacter is applied to degradation of terephthalic acid in printing and dyeing wastewater. The acinetobacter disclosed by the invention is better in degradation performance for terephthalic acid in the printing and dyeing wastewater, higher in application value, high in degradation efficiency, short in required time, better in degradation effect under an aerobic condition and wider in application range.

Description

technical field [0001] The invention relates to a strain of Acinetobacter and its preparation method and application, especially the application of terephthalic acid in degrading waste water, belonging to the technical field of microbial application. Background technique [0002] Alkali reduction wastewater is produced in the alkali reduction process of polyester fabrics. The main components of alkali reduction wastewater are terephthalic acid (PTA), ethylene glycol (EG), polyester oligomers and a small amount of additives (such as quarterly Ammonium salt cationic surfactant, alkali-resistant penetrating agent and N, N-polyoxyethylene alkylamine), etc., among which, PTA accounts for 63% to 71% of the total COD charge, and is a characteristic pollutant of alkali reduction wastewater [1]. In alkali reduction wastewater, PTA enters the environment in the form of "three wastes". In some wastewater (such as PTA production wastewater and polyester production wastewater), the conc...
