    • A new method to produce formulations of bacterial cellulose that exhibit improved viscosity-modifying properties particularly with low energy applied to effectuate viscosity changes therewith is provided. Such a method includes the novel co-precipitation with a water soluble co-agent that permits precipitation in the presence of excess alcohol to form an insoluble fiber that can than be utilized as a thickener or suspension aid without the need to introduce high energy mixing. Such bacterial cellulose properties have been available in the past but only through highly labor and energy intensive processes. Such an inventive method as now proposed thus provides a bacterial cellulose-containing formulation that exhibits not only properties that are as effective as those for previous bacterial celluloses, but, in some ways, improvements to such previous types. Certain end-use compositions and applications including these novel bacterial cellulose-containing formulations are also encompassed within this invention.
    • 提供了一种产生细菌纤维素制剂的新方法,其具有改善的粘度改性特性,特别是在施加低能量以实现其粘度变化的情况下。 这种方法包括与水溶性助剂的新型共沉淀,其允许在过量醇存在下沉淀以形成不能用作增稠剂或悬浮助剂而不需要引入高能量混合的不溶性纤维。 过去这种细菌纤维素的性质已经可以获得,但只能通过高度劳动和能量密集的方法。 因此,现在提出的这样一种本发明的方法提供了一种含细菌纤维素的制剂,其不仅具有与先前的细菌纤维素相同的效果,而且在某些方面表现出对这些以前类型的改进。 某些最终用途的组合物和应用包括这些新的含细菌纤维素的制剂也包括在本发明内。
