摘要：

Cross-polarization magic angle spinning (CPMAS) N-15 nuclear magnetic c resonance (NMR) spectroscopy was used to study the interactions between 2-aminobenzothiazole (ABT) and natural organic matt er in the presence of the natural laccase and synthetic air. Through the use of synthesized model compounds, we were able to confirm previous findings by CPMAS C-13 NMR spectroscopy that showed the formation of covalent amide bonds. We also provide evidence of the presence of two additional H bonds between ABT and the natural organic matter. Both H bonds involved amino and thiazole groups of ABT.
