Effects of Biochar on Microbial Communities in Soil-Plant Systems Contaminated by Antibiotics
One of the soil ecosystem's most intimate relationships between human life and wellness is the soil-plant system.A soil-plant pot experiment with antibiotics and biochar addition was carried out for 60 d in order to study the effects of biochar on the microbial community in soil-plant systems repaired by antibiotics.Based on high-throughput sequencing technology,the changes in the microbial community composition of soil and plants in different treatment groups were analyzed.The findings demonstrate that the relative abundance of Sphingomonadaceae is enhanced and the relative abundance of Nocardioides is dramatically lowered by antibiotic administration.The plant microbial community is not significantly affected by the addition of biochar,however the amount of Acidobacteria in the soil is enhanced.In summary,low amounts of antibiotics can be added to soil-plant systems to stimulate microbial communities,increase bacterial community abundance,and improve microbial community stability.However,because of the low concentration of biochar,the addition of biochar has no discernible impact on the microbial community.In the context of antibiotic contamination,this study contributes to a deep knowledge of the effects of biochar on alterations in the microbial population in the soil-plant system.
