摘　　要：细菌纤维素是一种由微生物合成的新型纳米材料,具有化学纯度高、持水性好、杨氏模量高、良好的生物相容性和可降解性等特性,广泛应用于食品、医疗、化工等领域。但发酵工艺落后、产量低、生产成本高一直是限制其应用于高附加值产品生产的瓶颈。本文概述纤维素产生菌及分离改良、发酵培养基优化、发酵条件对纤维素合成和产量的影响,以及发酵方式对BC产量和性能影响等方面的研究进展,并对BC在生产中的不足和未来应用前景进行展望,为开展更深入的研究和实际生产提供一定借鉴。Bacterial cellulose （BC） is a new type of nano material synthesized by some microorganisms, with high chemical purity, good water holding capacity, high Young＇s modulus, good biocompatibility and biodegradability and so on, widely used in food, medical, chemical and other fields. But the backward fermentation technology, low the yield of BC and high production costs have been to limit its application in the production of high value- added products. The research progress of bacteria producing cellulose and isolation, improved strains, optimization of fermentation culture medium, the influence of fermentation conditions on cellulose synthesis and yield, and the effect of fermentation on the yield and properties of BC were summarized, and the shortage of BC in production and its application prospect in the future are forecasted, which will provide some references for the further research and practical production.
