Abstract
Green technologies,e.g.,bioaugmentation and biostimulation,are cost effective and eco-friendly,and are becoming Rosetta Stone for the remediation of soil heavy metal and organic pollutants. Various bacteria,fungi and their consortia can be combined with physical and chemical techniques for the targeted remediation of soil organic contamination,heavy metal contamination and combined pollutions. This review exemplifies the representative studies within the recent five years,summarizes the screening of microbial strains from multiple sources and their potentials in transforming/degrading various types of pollutants,and highlights their applications in the case studies of laboratory,greenhouse and field conditions. The complexity of microbial remediation is ascribed to not only the variations of physiological and metabolic traits,but also numerous environmental factors,including abiotic factors,e.g.,pH,temperature,type of soil,pollutant concentration,content of water and organic matter,additional carbon and nitrogen sources,and biotic factors,e.g.,inoculum size, interactions between the introduced strains and autochthonous microbes,and the survival of inoculants. Prospects of combined remediation and the applications of molecular methods are also presented.关键词
