The influence of hemicelluloses on the aggregation of cellulose in higher plant cell walls was modelled by adding hemicelluloses to cultures of the cellulose producer Acetobacter xylinum. Characterization of the celluloses by X-ray diffractometry showed them to be more like those that occur in higher plants; the coaggregation of the hemicelluloses suggests their occlusion within and between the crystalline domains of the celluloses. The authors propose that hemicelluloses may be primary moderators of the tertiary structure of cell wall celluloses, allowing the development of a wide range of properties.
通过向纤维素产生菌木醋杆菌的培养物中添加半纤维素，模拟了半纤维素对高等植物细胞壁中纤维素聚集的影响。用X射线衍射法对纤维素进行表征，结果表明它们更类似于高等植物中存在的纤维素；半纤维素的共聚集表明它们被包埋在纤维素的结晶区域内和之间。作者提出，半纤维素可能是细胞壁纤维素三级结构的主要调节剂，从而使纤维素具有广泛的特性。
