从木醋酸杆菌获得的细菌-纤维素纳米纤维可以增强聚合物树脂，同时保持原始树脂的透明度，即使在纤维含量高达70wt.-%的情况下也是如此，因为纳米纤维不明显地散射可见光。用这种可再生资源增强的柔性塑料复合材料(见图)具有6 x 10(-6)度C(-1)的热膨胀系数，20 GPA的杨氏模数，拉伸强度达到325兆帕。
Bacterial-cellulose nanofibers obtained from Acetobacter xylinum can reinforce polymer resins while maintaining the transparency of the original resin, even at fiber contents as high as 70 wt.-%, because the nanofibers do not appreciably scatter visible light. The flexible plastic composites (see Figure) reinforced with this renewable resource have thermal expansion coefficients of 6 x 10(-6) degreesC(-1), Young's moduli of 20 GPa, and tensile strengths reaching 325 MPa.
