Application of Gene Bioaugmentation in Treatment of Recalcitrant Chemicals

Abstract:

One of the new approaches for bioaugmentation treatment of recalcitrant chemicals is gene bioaugmentation, which is helpful to improve the bioaugmentation stability when genetically engineered microorganisms are used. The mechanism of gene bioaugmentation, viz. horizontal gene transfer within microbial community, is introduced. The influence factors of gene bioaugmentation: gene vector, cell touch conditions and environment conditions, are discussed. The applications in soil bioremediation and wastewater treatment of gene bioaugmentation are also summarized. The limitation of gene bioaugmentation is also mentioned.
