摘要：

Cellulose from the bacterium Acetobacter xylinum was used as a model system for investigating the influence of other cell wall polysaccharides on the aggregation of cellulase. The patterns of aggregation of the bacterial cellulose were modified when the cellulose was produced in the presence of hemicellulose-like saccharides. The celluloses were found to be more like the I-beta-type found in higher plant celluloses than the I-alpha-type in the control bacterial celluloses. The effects of isolation procedures on structure were also explored. It was found that the structures of isolated celluloses were influenced by the procedures used in isolation.
