The aim of the present study was to obtain antimicrobial dressings from bacterial cellulose loaded with nutmeg and of fir needle essential oils. The attractive properties of BC, such as biocompatibility, good physicochemical and mechanical stability, and high water absorption, led to the choice of this material to be used as a support. Essential oils have been added to provide antimicrobial properties to these dressings. The results confirmed the presence of oils in the structure of the bacterial cellulose membrane and the ability of the materials to inhibit the adhesion of and . By performing antibacterial tests on membranes loaded with fir needle essential oil, we demonstrated the ability of these membranes to inhibit bacterial adhesion to the substrate. The samples loaded with nutmeg essential oil exhibited the ability to inhibit the adhesion of bacteria to the surface of the materials, with the 5% sample showing a significant decrease. The binding of essential oils to the membrane was confirmed by thermal analysis and infrared characterization.
本研究的目的是从负载肉豆蔻和冷杉针叶精油的细菌纤维素中获得抗菌敷料。细菌纤维素具有生物相容性、良好的物理化学和机械稳定性以及高吸水性等吸引人的特性,因此选择这种材料作为载体。添加精油是为了赋予这些敷料抗菌性能。结果证实了细菌纤维素膜结构中存在精油,以及这些材料具有抑制[具体细菌1]和[具体细菌2]粘附的能力。通过对负载冷杉针叶精油的膜进行抗菌测试,我们证明了这些膜能够抑制细菌粘附到基质上。负载肉豆蔻精油的样品表现出抑制细菌粘附到材料表面的能力,其中5%的样品有显著下降。通过热分析和红外表征证实了精油与膜的结合。
