Bacterial cellulose is a glucose biopolymer produced by microorganisms and widely used as a natural renewable and sustainable resource in the world. However, few bacterial cellulose-producing strains and low yield of cellulose greatly limited the development of bacterial cellulose. In this review, we summarized the 30 cellulose-producing bacteria reported so far, including the physiological functions and the metabolic synthesis mechanism of bacterial cellulose, and the involved three kinds of cellulose synthases (type I, type II, and type III), which are expected to provide a reference for the exploration of new cellulose-producing microbes.

细菌纤维素生物合成菌株及途径研究进展


细菌纤维素是由微生物产生的葡萄糖生物聚合物，作为天然可再生和可持续资源在世界范围内广泛使用。然而，细菌纤维素生产菌株少、纤维素产量低，极大地限制了细菌纤维素的发展。本文综述了迄今为止报道的30种产纤维素细菌，包括细菌纤维素的生理功能和代谢合成机制，以及涉及的3种纤维素合酶（I型、II型和III型），有望为新型纤维素生产微生物的探索提供参考。
