This study investigated the impact of nano-zero-valent iron (nZVI) on the removal of veterinary antibiotics by an anaerobic membrane bioreactor (AnMBR) for swine wastewater treatment. Ten veterinary antibiotics belonged to three commonly used groups, namely tetracyclines, fluoroquinolones, and sulfonamides, were evaluated. Results show that nZVI addition could improve AnMBR performance for the removal of both phosphorus and ammonium. Moreover, nZVI addition to AnMBR could improve the biodegradation of antibiotics to enhance their overall removal. Of the three groups of antibiotics, the enhancement was most obvious for sulfonamides with an increase in the removal rate from 32 – 62% to 64-97% when 2.6 g L-1 nZVI was added to AnMBR. Further microbial and redundancy analyses indicate that the removal of sulfonamides was closely and pos. correlated to the relative abundance of the genera Lentimicrobium and Methanomethylovorans. By contrast, nZVI reduced the removal of tetracycline, ciprofloxacin, and norfloxacin by AnMBR. Microbial anal. showed that nZVI dosage slightly reduced methane yield by promoting the growth of Mesotoga but reducing the proliferation of Methanomassiliicoccus to potentially disrupt the hydrogenotrophic pathway. In addition, adding nZVI reduced the ratios of protein to polysaccharide in both extracellular polymeric substances and soluble microbial products, thereby mitigating membrane fouling. In the experiment, the researchers used many compounds, for example, 4-Amino-N-(thiazol-2-yl)benzenesulfonamide (cas: 72-14-0Related Products of 72-14-0).
4-Amino-N-(thiazol-2-yl)benzenesulfonamide (cas: 72-14-0) belongs to thiazole derivatives. The higher aromaticity of thiazole is due to delocalization of a lone pair of sulfur electrons across the ring, which is evidenced by chemical shifts of ring hydrogen at δ 7.27 and 8.77 ppm (C2 and C4), indicating diamagnetic ring current. Thiazole is a versatile building block for the construction and lead generation of new drug discoveries. Numerous diazole-based compounds are in clinical use as anticancer, antileukemic, antiinflammatory, antiviral, antifungal, antirheumatic, immunomodulator, and antiparasitic agents.Related Products of 72-14-0
