Suspended solids in the nutrient medium for Acetobacter xylinium in a rotating disk bioreactor become incorporated into the gelatinous mat of bacterial cellulose as it forms. Embedding fibers of ordinary cellulose creates composites with enhanced strength and the toughness of bacterial cellulose. Purified cellulose and elongated fibers from paper are incorporated differently than are spherical particles such as silica gel. About 90% of the final cellulose can come from scrap paper, and dried composite sheets were much stronger than plain bacterial cellulose per unit area.
在旋转盘式生物反应器中，木醋杆菌营养培养基中的悬浮固体在细菌纤维素凝胶垫形成时会融入其中。嵌入普通纤维素纤维可形成强度和韧性增强的细菌纤维素复合材料。纯化纤维素和纸张中的细长纤维与硅胶等球形颗粒的掺入方式不同。最终纤维素约90%可来自废纸，干燥后的复合片材每单位面积的强度比普通细菌纤维素强得多。
