Biology

Bacterial cellulose (BC) considered as an important biopolymer because of its many more particular properties compared to plant cellulose. In cellulose-producing bacterial strains, most prominent of which is Gluconoacetobacter hansenii, BC biosynthesis is orchestrated by four genes; namely A, B, C, and D comprising a bacterial cellulose synthase (bcs) operon, preceded by two "regulatory" fragments. In some studies, it noted that BcsA and BcsB are two catalytic subunits that are present in all Bcs enzymes. Only bcsAB fragments are enough for effective in vitro BC production.When bcsA is activated by c-di-GMP, it incorporates glucose units into a cellulose chain in the cytoplasm using UDP glucose as a substrate. BcsB guides the glucan chain through the periplasm (1,2).
