Tổng hợp xà phòng Amoni và hoạt tính kháng khuẩn in vitro cuẩ nó đối với vi khuẩn xanthomonas oryzae pv.oryzae khi kết hợp với nano đồng/chitosan
Published: July 29, 2026
Abstract
Bài viết này trình bày phương pháp tổng hợp xà phòng amoni (AS) từ dầu cọ và khí NH3. AS thu được có dạng sệt, màu trắng đục và pH ~8.0. Hiệu quả kháng khuẩn (AE) trong phòng thí nghiệm đối với vi khuẩn Xanthomonas oryzae pv. oryzae (Xoo) của AS đạt 86,70% ở nồng độ 5000 mg/L và của nano Cu/chitosan (CuNPs/CS) đạt 100% ở nồng độ 30 mg/L Cu. Khi sử dụng CuNPs/CS ở nồng độ 20 mg/L Cu bổ sung 500 mg/L AS, AE đạt 100%. Như vậy, sự kết hợp giữa AS và CuNPs/CS được coi là giải pháp hiệu quả trong việc kháng lại vi khuẩn Xoo ở nồng độ thấp.
