Application of phanerochaete chrysosporium in degradation of tetracycline

Abstract

The invention relates to application of phanerochaete chrysosporium in degradation of tetracycline. According to the application, the microorganism species-phanerochaete chrysosporium which can degrade the tetracycline is discovered for the first time, and the content of the tetracycline in a water body can be easily, efficiently and quickly lowered through the action of biological metabolism and an enzyme system of the phanerochaete chrysosporium.

Description

technical field [0001] The invention relates to the field of microbiology and biodegradation, in particular to the application of Phanerochaete chrysosporium in degrading tetracycline. Background technique [0002] Antibiotics refer to a class of substances and their derivatives that are produced by bacteria, molds or other microorganisms during the reproduction process and can kill or inhibit other microorganisms. They are used to treat infections caused by sensitive microorganisms (usually bacteria or fungi). According to the statistics of the usage of antibiotics, in 1996, the amount of antibiotic feed additives used in the world accounted for 45.8% of the total amount of feed additives, and about 70% of the total output of antibiotics was used in animal husbandry; the veterinary drugs used in EU countries are mainly antibiotics and parasiticides Antibiotic veterinary drugs account for more than 70% of all veterinary drug consumption. The amount of antibiotics used in ea...

Problems solved by technology

However, from the reported literature, the existing methods still have the following problems: (1) using activated sludge adsorption to reduce the concentration of tetracycline in water, this method does not fundamentally reduce the content of tetracycline in the environment, and the residual The tetracycline in the excess sludge will bring the risk of secondary pollution to the environment; (2) The research on each process section in the sewage treatment plant shows that the primary treatment process of the sewage treatment plant has a negligible effect on the removal of antibiotic resistance genes ; The aerobic / anaerobic process in the secondary treatment process has a certain reduction effect on antibiotic resistance genes, but it is not obvious; (3) Using molecular methods, microorganisms have been found to be resistant to tetracyclines in activated sludge from sewage treatment plants. This provides a new idea for studying the degradation and removal of tetracycline from the perspective of microbiology, but the disadvantage of this method is that it cannot separate the live or pure microorganisms that can degrade tetracycline. no practical guidance
