一株具有提高油砂质量潜力的芽孢杆菌的研究。（注：原文中的“sp”推测可能是“Bacillus sp.”即芽孢杆菌属，这里按芽孢杆菌翻译，具体需结合更多背景信息确定）

A strain of sp, named as Y316, can degrade heavy fractions such as resins and asphaltenes in oil sand. We used Y316 to degrade oil sand samples for 35 days. After bacterial degradation, the oil sand degradation efficiency was 5.88%, while the degradation efficiency of the control group was only 0.29% under the same conditions. Compared with the control group, the saturated content of oil sand in the degradation group increased from 9.56 to 14.39%. After degradation, the resin and asphaltene fractions decreased by 5.34 and 4.77%, respectively. The results of the vaporizable fraction analysis also confirmed the degradation of heavy fractions and the formation of light fractions. After 35 days of degradation, the vaporizable fractions of saturates increased by 3.76 times. The results indicate that Y316 has great significance for improving the quality of oil sands and assisting in oil sand exploitation.

一种名为Y316的菌株能够降解油砂中的重质组分，如树脂和沥青质。我们使用Y316对油砂样品进行了35天的降解处理。细菌降解后，油砂降解效率为5.88%，而在相同条件下对照组的降解效率仅为0.29%。与对照组相比，降解组油砂的饱和烃含量从9.56%增加到了14.39%。降解后，树脂和沥青质组分分别减少了5.34%和4.77%。可挥发组分分析结果也证实了重质组分的降解和轻质组分的生成。降解35天后，饱和烃的可挥发组分增加了3.76倍。结果表明，Y316对于提高油砂质量和辅助油砂开采具有重要意义。
