Indole, a typical nitrogen heterocyclic aromatic pollutant, is extensively spread in industrial wastewater. Microbial degradation has been proven to be a feasible approach to remove indole, whereas the microbial resources are fairly limited. A bacterial strain designated as SHE was isolated and found to be an efficient indole degrader. It was identified as Cupriavidus sp. according to 16 SrRNA gene analysis. Strain SHE could utilize indole as the sole carbon source and almost completely degrade 100 mg/L of indole within 24 hr. It still harbored relatively high indole degradation capacity within p H 4–9 and temperature 25°C–35°C. Experiments also showed that some heavy metals such as Mn2＋, Pb2＋and Co2＋did not pose severe inhibition on indole degradation. Based on high performance liquid chromatography–mass spectrum analysis, isatin was identified as a minor intermediate during the process of indole biodegradation. A major yellow product with m/z 265.0605（C15H8N2O3） was generated and accumulated, suggesting a novel indole conversion pathway existed. Genome analysis of strain SHE indicated that there existed a rich set of oxidoreductases, which might be the key reason for the efficient degradation of indole. The robust degradation ability of strain SHE makes it a promising candidate for the treatment of indole containing wastewater.

为了提升快速公交的运行效率,并适应客流需求分布情况,提出一种多模式调度与沿线交叉口信号配时协同优化方法。采用数学规划的建模方法,首先基于快速公交调度模式与沿线交叉口信号配时关联性的考虑,采用递推思想,描述快速公交车辆运行状态和公交乘客出行状态。进而以乘客总出行时间最小为优化目标,考虑信号控制、交叉口饱和度、快速公交调度模式选择、乘客候车时间等实际运行约束条件,建立非线性规划模型,将发车时刻、停站策略和交叉口信号配时构建在一个统一的模型中进行同步优化。模型考虑了信号配时调整对社会车辆的负面影响,包括保持现存的线协调控制以及饱和度的上限,保障社会车辆的服务水平不显著恶化。模型采用遗传算法求解。最后通过算例分析,验证模型在不同工况下的优化效益,较单独使用多模式调度和信号控制优化,乘客总出行时间分别减少约7.5%和15%,公交车辆在交叉口延误分别减少约15%和45%。研究结果表明:优化模型可根据客流分布情况调整快速公交停站策略,并将信号配时与公交通行和驻站相协调以减少交叉口延误。公交调度和信号控制的协同优化可在更大的可行域范围内搜索最优解,从而提升快速公交运行效率。
