摘要本研究试图评价在淹水条件下湿地植物对菲(Phe)的消散能力。结果表明，香椿和香根草均能有效地降解Phe，且在植物栽培和接种假单胞菌(ATCC BAA-257)的条件下效果更好。在植物栽培的所有处理中，Phe的浓度从200mgkg−-1下降到低于52mgkg-1。在试验结束时，在接种细菌的植物组合培养中检测不到Phe。微生物生物量C(碳)、N(氮)和P(磷)在有无细菌接种的情况下差异显著(p<；0.05)，接种细菌显著增加微生物量P(p<；0.05)，接种细菌和不同植物种类显著降低微生态系统中Phe的浓度(p<；0.05)。细菌的接种和植物根系分泌物的释放进一步促进了Phe在沙地中的消散。在接种细菌的处理中，柠檬酸和苹果酸的浓度降低了69%，表明大量的柠檬酸和苹果酸是细菌的食物来源和生长底物。
ABSTRACT This study attempts to evaluate the capacity of wetland plants' ability to dissipate phenanthrene (PHE) under waterlogged conditions. The results indicate that Typha latifolia and Vetiveria zizanioides may efficiently degrade PHE, and were much more effective when under combined plant cultivation with the inoculation of Pseudomonas frederiksbergensis (ATCC BAA-257) . Concentrations of PHE declined from 200 to less than 52 mg kg−1 in all treatments with plant cultivation. At the end of the experimental period, PHE was undetectable in combined plant cultivation in the presence of bacteria inoculation. Microbial biomass C(carbon), N(nitrogen), and P(phosphate) were significantly different (p < 0.05) in the presence and absence of bacteria inoculation with bacteria inoculation significantly (p < 0.05) increased microbial biomass P. The presence of bacteria inoculation and different plant species significantly (p < 0.05) decreased the PHE concentrations in the microcosms. The inoculation of bacteria and release of exudates from plant roots further enhanced the dissipation of PHE in sand. Concentrations of citric and malic acids were decreased up to 69% in bacteria-inoculated treatments, showing large citric and malic acids serving as a food source and growth substrate for bacteria.
