Degradation bacteria for sulfonamide antibiotics and application thereof

Abstract

The invention discloses a degradation bacteria for sulfonamide antibiotics and an application thereof, wherein the bacteria is Sakaguchia cladiensis A5 and is preserved in Guangdong Center of Microbial Culture Collection at Jan. 26th, 2018, and is assigned the accession number of GDMCC No.60319. The bacterial strain has great degradation effect on sulfonamide antibiotics such as sulfamerazine, sulfamethoxazole and the like, and can be used for degradation treatment to sulfonamide antibiotics pollution to application objects comprising wastewater, waste residue, water environment, soil and thelike, which contain the sulfonamide antibiotics. The bacterial strain can reduce damage on ecological environmental safety due to the antibiotics, is energy-saving and environment-friendly, and has extensive application prospect.

Description

technical field

[0001] The invention belongs to the technical field of environmental pollutant treatment. More specifically, it relates to a sulfonamide antibiotic degrading bacterium and its application. Background technique

[0002] my country is a big country in the production and use of antibiotics. Thousands of tons of antibiotics are used in poultry farming and personal medical care every year. Among them, sulfonamide antibiotics have become my country's pharmaceutical and veterinary antibiotics due to their broad-spectrum, high quality and low price advantages. The most widely used category. In fact, most antibiotics are not fully absorbed by the body. Studies have found that up to 85% to 90% of antibiotics enter the environment through excrement in the form of drug prototypes or metabolites, causing serious pollution to soil and water. Mo Cehui's research group mainly focused on the impact of antibiotic pollution on vegetable planting and agricultural food safety i...
