摘要

甲壳素被用于农业以提高作物产量;然而,由于处理困难,其使用受到限制。甲壳素纳米纤维(CNF)克服了这一问题,并且由于其诱导子活性,在作物保护方面具有巨大的潜力。为了扩大CNF的利用率,使用化学还原方法制备了基于铜纳米颗粒的抗微生物CNF(CuNPs/CNF)。通过扫描电子显微镜证实了CuNPs的形成。热重分析显示,CNF上的CuNP的量与前体盐醋酸铜呈剂量依赖关系。CuNPs赋予CNF对brassicicola链格孢菌和carotovorum乳杆菌具有较强的抗菌活性。此外,CuNPs/CNF降低了卷心菜的病原体感染。与相应的CNF或商业化农药波尔多处理相比,CuNPs/CNF的抗菌活性和疾病预防作用有所提高。这些结果表明,CuNPs赋予CNF抗菌活性,并提高了植物病害保护的功效。

Production of copper nanoparticle-immobilized chitin nanofibers and their role in plant disease control.

Chitin is used in agriculture to improve crop production; however, its use is limited due to difficulties in its handling. A chitin nanofiber (CNF) overcomes this issue and, due to its elicitor activity, has great potential for crop protection. To expand CNF utilization, a copper nanoparticles-based antimicrobic CNF (CuNPs/CNF) was prepared using a chemical reduction method. The formation of CuNPs was confirmed via scanning electron microscopy. Thermogravimetric analysis revealed that the amount of CuNPs on the CNF was dose-dependent on the precursor salt, copper acetate. CuNPs endowed the CNF with strong antimicrobial activity against Alternaria brassicicola and Pectobacterium carotovorum. Moreover, the CuNPs/CNF reduced pathogen infection in cabbage. The antimicrobial activity and disease prevention of the CuNPs/CNF was increased compared to the corresponding CNF or commercial agrochemical Bordeaux treatment. These results indicate that CuNPs conferred antimicrobial activity on the CNF and increased the efficacy of plant disease protection.
