This study investigated the effects of applying different biochars to soil on shifts in the bacterial community, the biodegradation of antibiotics, and their relationships. In total, nine biochars were applied to agricultural soil contaminated with 16 antibiotics. Clustering anal. showed that the responses of bacteria at the genus level to biochars were highly dependent on the biochar feedstock rather than the pyrolysis temperature Among the antibiotics tested in the study, the biodegradation percentage was lower for tetracyclines (TCs, 6-14%) than sulfonamides (SAs, 8-26%) and quinolones (QLs, 8-24%). For specific individual antibiotics from the same class with similar structures, the high adsorption affinity of soil particles for antibiotics due to hydrophobic interactions (logKow) and electrostatic interactions (pKa) resulted in low biodegradation percentages for antibiotics in the soil. The biodegradation of TCs was affected more by the biochar type (effect size: -10% to 42%) than those of QLs (-26% to 14%) and SAs (-24% to 22%). According to the relationships determined between the bacterial taxonomic composition and biodegradation of antibiotics, Steroidobacter from the phylum Proteobacteria has significant pos. correlations with the biodegradation of all SAs (p < 0.01), thereby indicating that Steroidobacter had a high capacity for biodegrading SAs. Significant pos. correlations were also detected (p < 0.05) between specific genera (Iamia, Parviterribacter, and Gaiella) from the phylum Actinobacteria and the biodegradation of SAs. No significant pos. correlations were found between bacterial genera and the biodegradation percentages for QLs and TCs, possibly due to the specific microorganisms involved in these biodegradation processes. The results in this study provide insights into the biodegradation mechanisms of antibiotics in soil and they may facilitate the development of strategies for the bioremediation of antibiotic-contaminated soil. In the experiment, the researchers used many compounds, for example, 4-Amino-N-(6-methoxypyrimidin-4-yl)benzenesulfonamide (cas: 1220-83-3Application of 1220-83-3).
4-Amino-N-(6-methoxypyrimidin-4-yl)benzenesulfonamide (cas: 1220-83-3) belongs to pyrimidine derivatives. Pyrimidine also found in many synthetic compounds such as barbiturates and the HIV drug, zidovudine. As nucleotides in DNA and RNA, pyrimidine nucleotide derivatives have a wide range of biological applications. For example, pyrimidine derivatives are useful in DNA repair studies involving cancer and epigenetics.Application of 1220-83-3
