Synergic degradation of diesel by Scirpus triqueter and its endophytic bacteria

The endophytic bacterium isolated from Scirpus triqueter was proved to be an oil-degraded bacterium. A pot experiment was conducted to investigate the removal ratio of diesel under the combined effect of oil-degraded microorganism (Pseudomonas sp. J4AJ) and S. triqueter. The effect of diesel on plant growth parameters, soil enzymes and microbial community was assessed after 60 days. The results showed that the soils which were planted with S. triqueter and inoculated with J4AJ displayed the highest removal ratio (54.51?±?0.15 %) after 60-day experiment. However, the removal ratio of J4AJ-treated soils was 38.97?±?0.55 %. Diesel was toxic to S. triqueter, as evidenced by growth inhibition during the experimental period. However, the plant height and stem biomass in the soils inoculated with J4AJ significantly increased. The combined effect of S. triqueter and J4AJ improved the enzyme activities of the catalase and dehydrogenase in the contaminated soil. The diversity index in soils under the effect of S. triqueter combined with J4AJ was lower than that of the other soil samples. The principal analysis of phospholipid fatty acid signatures revealed that the combined effect of S. triqueter and J4AJ increased the differences of soil microbial community structure with the other treatments.     

主要污染物排污权有偿使用定价研究——以温州为例

文章对重点污染行业和一般行业的定价方案、排污权时限、定价方式等进行系统研究。采用环境容量资源恢复成本定价法,以社会平均污染治理成本为基础,考虑排污权时限及贴现率方式,来估算排污权初始分配价格的参考值,同时调研重点污染和一般行业的二氧化硫、氮氧化物、COD和氨氮的消减成本,以重点污染和一般行业污染物消减成本为基础,再考虑温州的经济状况及环境质量状况确定估算排污权初始分配价格,详细评估温州排污权交易初始价格标准,并提出了温州市初始排污权有偿使用费、政府储备排污权有偿使用费征收标准。
