Abstract

Landfill is the common method of waste management in most part of the world particularly developing countries due to low technology know-how. This method of solid waste disposal is meant to better the living standard of mankind but the unplanned production of landfill leachate reverse the same standard by impacting negatively to the environment which in turn affect mankind. Different method of treating landfill leachate have been develop, but most of this method are not easily accessible, the use of microbe for biological treatment of landfill leachate has gained the attention of researchers since the potentiality of many microbe has been attested for high pollutant reduction efficiency from landfill leachate but the onsite application of this method remains a problem owing to the lack of genomic, metabolomic and proteomic details to prove the efficiency of this microbes to effectively degrade pollutants from landfill leachates. This mini-review is aimed at evaluating the contribution of microbe towards the success of landfill leachate treatment and the role of molecular genomics in achieving the onsite treatment of landfill leachates. The mini-review report the role of metanogenic and acetogenic bacteria in the formation of landfill leachate, current trend in biological treatment of landfill leachate, the role of mycoremediation, phycoremediation and bioremediation (bacteria) in landfill leachates treatment and current contribution and the future of molecular tool in increasing the efficiency of microbe in landfill leachates treatment. The molecular genomics of microbe used in the treatment of landfill leachates need to be further studied to attest the role of genomics, proteomics and metabolomic constituent for efficient onsite application.
