Example Embodiment

[0010] Specific embodiment 1: The new use of a Klebsiella strain of this embodiment, which is used to remove tetracycline from water, and the Klebsiella is Klebsiella sp. MFX strain.

Example Embodiment

[0011] Specific embodiment two: this embodiment is different from specific embodiment one in that: the strain is Klebsiella sp. MFX strain, the preservation number: CGMCC No.6243, the preservation unit is: China Microbial Culture Collection Management Committee General Microbiology Center, the preservation address is: No. 1 Beichen West Road, Chaoyang District, Beijing, China, and the preservation date is: June 20, 2012. Others are the same as the first embodiment.

Example Embodiment

[0012] Specific embodiment three: This embodiment is different from the specific embodiment 1: The specific operation of using Klebsiella to remove tetracycline from water is as follows:

[0013] 1. Add microbial flocculant and coagulant aid to tetracycline water to obtain a mixed solution; wherein the volume ratio of microbial flocculant to tetracycline water is 3:100; the volume ratio of coagulant aid to tetracycline water is 9:10000;

[0014] 2. After adjusting the pH value of the mixed solution, put it into a shaker, shake for 0.1 to 90 minutes, and then take it out and let it stand for 5 minutes to complete;

[0015] Among them, the preparation process of the microbial flocculant is as follows: Mix the dry powder of the microbial flocculant MFX with distilled water in a mass-volume ratio of 1g:480~520mL, place it on a magnetic stirrer, and obtain a microbe with a concentration of 2.0g / L after stirring. Flocculant; The microbial flocculant MFX dry powder is prepared from Klebsiel...

Abstract

The invention relates to new application of Klebsiella sp.. Strains are used for removing tetracycline in water. The tetracycline removal rate of the Klebsiella sp. MFX strains can reach 71.68%.

Description

technical field [0001] The present invention relates to a new application of Klebsiella Background technique [0002] In the late 1990s, as a new type of pollutant in the environment, antibiotics began to attract widespread attention from foreign scholars for their environmental pollution and harm. Drugs for humans or animals are the main source of antibiotics. After the drugs are ingested by humans or animals, only a small part is actually metabolized, and most of them are excreted in the form of parent compounds or metabolites through animal feces and urine and enter the breeding wastewater Or in the surrounding water environment medium. The impact of antibiotic pollution in the water environment on human health is mainly manifested in the following two points: Pollution of drinking water and potential harm such as triple effects and intestinal flora imbalance; pollution of soil and food, and ultimately indirect harm to humans. Among them, antibiotics such as tetracyclin...
