微生物纤维素是一种具有广泛应用的纯净形式的纤维素。由于其高液体吸收性和卫生特性，非常适用于医疗用途，特别是伤口敷料。在这项研究中，微生物纤维素在静态介质（Hestrin 和 Scharm）中通过 Xylinium 醋酸杆菌生物合成 6 天，在棉纱布样品上形成/涂覆。测定了处理过的纱布样品的一些基本因素，如吸水性、干燥时间（持水时间）和垂直芯吸量，并与未处理的样品进行比较。结果表明，涂有微生物纤维素的棉纱布的吸水性和芯吸能力提高了30%以上，干燥时间缩短了约33%。可以得出结论，用微生物纤维素覆盖棉纱布可以提升其特别用于伤口敷料的一些重要特性。
Microbial cellulose is a pure form of cellulose with widespread applications. It is very applicable for medical usage specially wound dressings due to its high liquid absorbency and hygienic nature. In this study, microbial cellulose formed/coated on cotton gauze samples during its biosynthesis in a static medium (Hestrin & Scharm) for 6 days by Acetobacter Xylinium. Some essential factors of treated gauze samples, like water absorbency, drying time (water holding time), and amount of vertical wicking were determined and compared with untreated samples. Results showed that cotton gauze coating with microbial cellulose increases water absorbency and wicking ability over 30%, and reduces drying time about 33%. It can be concluded that covering of cotton gauze with microbial cellulose can promote some important characteristics of it specially for wound dressings.
