In this paper, we perform a systematic analysis of the structural organization of bacterial cellulose (BC). We report four types of organization of the BC mass, produced by Gluconacetobacter hansenii that occur depending on cultivation conditions. Two of those, particularly, plywood type one and layers of micro-sized tubes were observed and described for the first time. In spherical BC particles (pellets), we found the layered structure that had previously been reported for planar geometry only. We suggest a model explaining why layers form in BC films and attempt to reveal the impact of different factors on the BC microscale morphology. We assume that the main factor that has direct impact on the type of structure formed is the rate of BC mass accumulation.

在本文中，我们对细菌纤维素（BC）的结构组织进行了系统分析。我们报告了由汉逊氏糖杆菌产生的四种类型的细菌培养组织，具体取决于培养条件。首次观察到并描述了其中的两种，特别是一种胶合板和几层微型管。在球形BC颗粒（小丸）中，我们发现了以前仅针对平面几何形状的分层结构。我们建议建立一个模型，解释为什么在BC膜中形成层，并试图揭示不同因素对BC微尺度形态的影响。我们假设对形成的结构类型有直接影响的主要因素是BC的质量积累率。
