With the increasing successful stories of decontamination, different strategies for metal remediation are gaining importance and popularization in developing countries. Rhizoremediation, is one such promising option that harnesses the impressive capabilities of microorganisms associated with roots to degrade organic pollutants and transform toxic metals. Since it is a plant based in-situ phytorestoration technique it is proven to be economical, efficient and easy to implement under field conditions.Plants grown in metal contaminated sites harbor unique metal tolerant and resistant microbial communities in their rhizosphere. These rhizo-microflora secrete plant growth promoting substances, siderophores, phytochelators to alleviate metal toxicity, enhance the bioavailability of metals (phytoremediation) and complexation of metals (phytostabilisation). Selection of right bacteria/consortia and inoculation to seed/ roots of suitable plant species will widen the perspectives of rhizoremediation.
随着去污的成功案例越来越多，不同的金属修复策略在发展中国家变得越来越重要和普及。根际修复就是这样一种很有前途的选择，它利用与根相关的微生物的惊人能力来降解有机污染物和转化有毒金属。由于它是一种基于植物的原位植物修复技术，因此被证明在经济上是可行的，在现场条件下效率高且易于实施。在金属污染的地点生长的植物在其根际中拥有独特的耐受和抵抗金属的微生物群落。这些根际微生物会分泌植物生长促进物质、铁载体、植物螯合剂来减轻金属毒性，提高金属的生物利用度（植物修复）和金属的络合（植物稳定化）。选择合适的细菌/菌群并接种到合适植物物种的种子/根部，将拓宽根际修复的前景。
