Synthesis of ammonium soap and its in vitro antibacterial activity against xanthomonas oryzae pv.oryzae when combined with copper nanoparticles/chitosan
Xuất bản: tháng 7 29, 2026
Tóm tắt
This paper presented a method for synthesizing ammonium soap (AS) from palm oil and NH3 gas. The obtained AS was viscous, opaque white, and pH ~8.0. In vitro antibacterial efficiency (AE) against Xanthomonas oryzae pv.oryzae (Xoo) of AS reached 86.70% at a concentration of 5000 mg/L and that of Cu nanoparticles/chitosan (CuNPs/CS) reached 100% at a concentration of 30 mg/L Cu. When using CuNPs/CS at a concentration of 20 mg/L Cu supplemented with 500 mg/L AS, AE reached 100%. Thus, the combination of AS and CuNPs/CS is considered an effective solution for resisting Xoo at low concentrations.
