On June 1st, 2022, Professor Guang Yang’s 3-Bio Group at Department of Biomedical Engineering, College of Life Science and Technology, Huazhong University of Science and Technology published a review article entitled “Bacterial cellulose: Molecular regulation of biosynthesis, supramolecular assembly, and tailored structural and functional properties” in the internationally renowned journal《Progress In Materials Science》 (Imact Factor: 39.58).
In recent years, Professor Yang's 3-Bio Group has carried out a series of bais and applied research on the synthesis, regulation, and functionalization of bacterial cellulose (BC). Among the different types of nanocellulose being investigated, bacterial cellulose (BC) or bacterial nanocellulose (BNC) is receiving tremendous attention due to its purity and superior features. Either alone or in the form of composites, BC finds diverse applications in different fields.
This review systematically summarizes the biosynthesis of bacterial cellulose and the extracellular transport mechanism of microorganisms, which is helpful for researchers to further understand the molecular and regulatory mechanism of cellulose biosynthesis in bacterial cells and the cell-free systems, and further promote the understanding of the structure and regulation of bacterial cellulose. Thereby promoting the improvement of the structure and functional characteristics of bacterial cellulose and opening the door for new applications of bacterial cellulose in different fields. The development of BC-based composite functional materials, BC-based block copolymers, and the methods of producing hybrid cellulose by using genetic engineering vectors and tissue engineered plants introduced in this review will provide a platform for molecular biologists and material engineers to design composite materials with novel functions and applications.
