以烃/水两相体系中细菌数量为指标，研究了从鲤鱼池塘中分离的芽孢杆菌YB-030518和YB-034325细胞壁疏水性及其在不同培养条件下的变化。我们研究了细胞壁疏水性对这些细菌作为益生菌在基于虾饲料的生物修复中的作用的影响。培养条件如生长期、pH和温度影响芽孢杆菌属细胞表面的疏水性质。在对数生长期（18 h），YB-030518和YB-034325的疏水性均显著高于96 h（P<0.05）。YB-034325的疏水性显著高于YB-030518（5 °C，pH 5.5和pH 8.5; 20 °C，pH 5.5和pH 7.0）（P<0.05）。然而，对于任何单一益生菌，在不同pH值（5.5、7.0和8.5）或不同温度（5 °C和20 °C）下，细胞壁疏水性没有统计学差异（P>0.05）。高疏水性菌株YB-034325的相对生长速率显著高于YB-030518（P<0.05）。在48 h和96 h时，YB-034325的生物修复能力显著高于YB-030518和对照（P<0.05）。此外，益生菌芽孢杆菌YB-030518和YB-034325处理的平均生物修复能力显著高于对照（P<0.05）。
The cell wall hydrophobicity of Bacillus sp. YB-030518 and YB-034325 isolated from carp (Cyprinus carpio) ponds and its changes under different culture conditions were studied on the basis of the amount of bacteria in a hydrocarbon/water two-phase system. We investigated the effect of cell wall hydrophobicity on the role of these bacteria as probiotics in bioremediation based on shrimp feed. Culture conditions such as growth phase, pH and temperature influence the hydrophobic properties of the Bacillus sp. cell surface. In the exponential growth phase (18 h), the hydrophobicity of both YB-030518 and YB-034325 was significantly higher (P<0.05) than that at 96 h. The hydrophobicity of YB-034325 was significantly higher (P<0.05) than that of YB-030518 (5 °C at pH 5.5 and pH 8.5; 20 °C at pH 5.5 and pH 7.0). However, for any single probiotic, there was no statistical difference (P>0.05) in cell wall hydrophobicity at different pH values (5.5, 7.0 and 8.5) or at different temperatures (5 °C and 20 °C). The relative growth rate of YB-034325 with a high level of hydrophobicity was significantly higher (P<0.05) than that of YB-030518. The bioremediation capability at 48 h and 96 h was significantly higher in YB-034325 (P<0.05) compared to YB-030518 and the Control. Moreover, the mean bioremediation capability of treatment with probiotics Bacillus sp. YB-030518 and YB-034325 was significantly higher (P<0.05) than that of the Control.
