Abstract

ABSTRACT This study aims to construct an ε‐polylysine (EPL)–sodium alginate (SA) composite microcapsule system (EPL/OEO@SAM) via electrostatic composite‐emulsification crosslinking method. The optimal preparation parameters were determined as 0.25% EPL concentration and 5 min reaction time, achieving a maximum EE of 34.24%. Multi‐dimensional characterizations confirmed the successful formation of EPL‐SA polyelectrolyte complexes and core‐shell structure of composite microcapsules. Antibacterial tests showed that EPL/OEO@SAM had significantly enhanced inhibitory effects against all dominant wood‐degrading microorganisms isolated from the Tianluoshan site, with the largest inhibition zone diameter of 32.67 ± 2.52 mm against Trichoderma breve (PM2). The minimum inhibitory concentration (MIC) was 0.64 g/L. This study provides a more efficient and durable antibacterial material for the in situ conservation of waterlogged wooden cultural relics.

浸水木质文物原位保护的ε -聚赖氨酸复合微胶囊

摘要：本研究旨在通过静电复合乳化交联法构建ε -聚赖氨酸(EPL) -海藻酸钠（SA）复合微胶囊体系（EPL/OEO@SAM）。最佳制备工艺为EPL浓度为0.25%，反应时间为5 min，最大EE为34.24%。多维表征证实了EPL - SA多电解质复合物的成功形成和复合微胶囊的核壳结构。抑菌试验表明，EPL/OEO@SAM对天罗山基地分离的所有优势木材降解微生物均有显著的抑制作用，对短木霉（Trichoderma breve, PM2）的最大抑制带直径为32.67±2.52 mm。最低抑菌浓度（MIC）为0.64 g/L。本研究为浸水木质文物的原位保护提供了一种更高效、耐用的抗菌材料。

期刊介绍： Archaeometry is an international research journal covering the application of the physical and biological sciences to archaeology, anthropology and art history. Topics covered include dating methods, artifact studies, mathematical methods, remote sensing techniques, conservation science, environmental reconstruction, biological anthropology and archaeological theory. Papers are expected to have a clear archaeological, anthropological or art historical context, be of the highest scientific standards, and to present data of international relevance. The journal is published on behalf of the Research Laboratory for Archaeology and the History of Art, Oxford University, in association with Gesellschaft für Naturwissenschaftliche Archäologie, ARCHAEOMETRIE, the Society for Archaeological Sciences (SAS), and Associazione Italian di Archeometria.
