中文摘要:

      细菌纤维素(Bacterial Cellulose, BC), 是由细菌产生的胞外产物, 因由细菌产生, 故其命名为细菌纤维素。细菌纤维素因其具有高持水性、高结晶度、超细纳米纤维网络、高弹性模量和抗拉强度等独特的性质, 而被广泛地应用在食品及医学中。本文综述了细菌纤维素在食品、新型伤口敷料、人体组织材料、人工角膜和心脏瓣膜、药物结合或释放以及医用产品开发新兴领域的应用和发展前景。细菌纤维素生产出的产品不仅口感美味, 而且作为健康食品, 可降低人体胆固醇而拥有保健价值。医学方面期望细菌纤维素能够依据其独特的性质在更广泛的领域得到长足发展。相信在不久的将来, 日益完善的生产技术能让细菌纤维素更好地为人类服务。

英文摘要:

      Bacterial Cellulose (BC for short), is a product produced by bacteria extracellularly, so named Bacterial Cellulose. Bacterial Cellulose is widely used in food and medicine because of its unique properties, such as high water holding capacity, high crystallinity, nanofibre-network structure, high elastic modulus and tensile strength. This article briefly summarizes the recent developments and applications of bacterial cellulose in the food, emerging field of novel wound dressing, human tissue materials, artificial cornea and heart valves，the drug combination or release, and medical products. Products of BC is not only delicious, but also as a health food, have lower cholesterol levels and health care value. Medicine of bacterial cellulose is expected in the broader field to get a long-term development according to its unique properties. In the near future, the increasingly perfect production technology can make bacterial cellulose serve humans better.
