| Abstract: |
| Antibiotics, a group of chemicals, are widely used in treating human diseases and animal diseases and promoting animal growth. It was estimated that approximately 2300 tons of antibiotics were consumed in veterinary medicine in European countries and about 52% of all antibiotics(approximately 162000 tons) were used for veterinary medicine in China in 2013. However, antibiotics could not be completely absorbed by the animal body, and most is excreted along with urine or feces, either unaltered or as metabolites. Antibiotics entered the environmental compartments at high rates, which resulted in concerns over public health, resource utilization and environmental pollution. Therefore, more and more attention has been paid to their effective elimination in the environment. The degradation of antibiotics by special microorganisms has been considered to be an efficient method for getting rid of antibiotics from the environment because of its low cost, simple management, and high degradation rates compared to other methods such as advanced oxidation processes, active carbon adsorption, low-temperature plasma technology, and membrane processing. In the present paper, the progress in antibiotic degradation by microorganisms and its mechanisms were reviewed in aspects of screening of specific functional microorganisms responsible for antibiotic degradation, optimization of microbial degradation conditions, degradation efficiencies and mechanisms including molecular biological mechanisms and degradation pathways. In addition, future research directions on microbial degradation of antibiotics were also proposed. |
