摘要: Abstract Utilizing plants to remediate heavy metal contaminated soils, a process known as phytoextraction, offers many advantages but has yet reach levels of efficiency that would make the strategy economically viable. Inoculation plant rhizosphere with microorganisms is an established route improving phytoextraction efficiency. In general, can improve by increasing availability metals and biomass. This review uses meta-analysis results from 103 microbial-augmented studies examine if one these microbial mechanisms greater potential positively impact phytoextraction. Trends surrounding use metal-accumulating versus non-heavy-metal-accumulating in are discussed. Microbially induced improvements accumulation biomass, focus several studies, always coincident enhanced net However, treatments improved biomass more prevalent literature account for larger number reported particularly plants. The experimental findings emerging implicate specific processes briefly reviewed used underline trends observed indicate future directions regarding
