%X 利用鞘氨醇单胞菌对丁苯橡胶（SBR）胶粉进行脱硫，对比研究SBR胶粉和脱硫SBR胶粉填充SBR胶料的性能。结果表明：鞘氨醇单胞菌不仅可使硫交联键断裂，也可使橡胶主链上的部分碳-碳双键断裂。与SBR胶粉填充的SBR胶料相比，脱硫SBR胶粉填充SBR胶料的转矩和表观交联密度减小，拉伸强度和拉断伸长率增大，邵尔A型硬度和撕裂强度保持不变，阿克隆磨耗量减小，脱硫SBR胶粉与SBR基体结合较紧密，动态滞后损失较小。;SBR ground rubber was desulfurized using Sphingomonas sp.，and the properties of desulfurized SBR ground rubber filled SBR were investigated and compared to regular SBR ground rubber filled SBR.The results showed that，Sphingomonas sp. not only could break sulfur crosslinked bond，but also might partially rupture the carbon-carbon double bonds in rubber main chain.Compared with SBR ground rubber filled SBR compound，the torque and apparent crosslink density of desulfurized SBR ground rubber filled SBR decreased，tensile strength and elongation at break increased，Shore A hardness and tear strength kept at same levels，and Akron abrasion loss decreased.Desulfurized SBR ground rubber bound much stronger with SBR matrix，and the dynamic hysteresis loss was lower
