英文摘要	Bacterial cellulose (BC) is a promising biomaterial as well as a model system useful for investigating cellulose biosynthesis. BC produced under static cultivation condition is a hydrous pellicle consisting of an interconnected network of ﬁbrils assembled in numerous dense layers. The mechanisms responsible for this layered BC assembly remain unknown. This study used calcoﬂuor as a ﬂuorescent marker to examine BC layer formation at the air/liquid interface. Layers are found to move downward into the media after formation while new layers continue to form at the air/liquid interface. Calcoﬂour is also known to reduce the crystallinity of cellulose, chang- ing the mechanical properties of the formed BC microﬁbrils. Consecutive addition and accumulation of calcoﬂuor in the culture medium is found to disrupt the layered assembly of BC. BC crystalllinity decreased by 22 % in the presence of 12 % calcoﬂuor (v/v) in the medium as compared to BC produced without calcoﬂuor. This result suggests that cellulose crystallinity and the mechanical perties which crystallinity provides to cellulose are major factors inﬂuencing the layered BC structure formed during biosynthesis.
