原始语种摘要: Abstract(#br)Tungsten is an emerging contaminant because of its potential toxicity to humans. However, tungsten-plant-microbe interactions remains unknown. The objective of the study was to evaluate the effect of tungsten-resistant bacteria on tungsten species in plants and microbial community structure in soil. Although bacterial inoculation did not affect lettuce ( Lactuca sativa L.) growth or tungsten uptake via root, tungsten-resistant bacteria increased translocation of tungsten from root to shoot. Bacterial inoculation slightly oxidized tungsten in lettuce based on tungsten L 3 x-ray absorption near-edge structure (XANES). Tungsten in lettuce roots and shoots grown in tungsten(VI)-spiked soil existed as a mixture of tungsten(IV) and tungsten(VI). Tungsten accumulated as...
