Humic acids are natural non-living organic substances and they are extremely resistant to biodegradation. Microorganisms are the driving force behind the transformation and mineralization of humic acids. However, their relative abundance and role during turnover of humic acids in landfill leachate treatments are still unclear, there is still a gap in our knowledge. This work was therefore undertaken with the aim of investigating the role of landfill leachate microbial communities in humic acids transformation and to highlight the problems, unsolved questions in leachate treatment. The results shown:The microorganisms can synthesize the humus in the condition of carbon source rich, but on the other hand, when the carbon source is lack, humus also can be used as the nutrient substance. Under different dilution degrees, microorganisms have different ability to degrade humus. At a microbial rate of 80% 、60% 、50% 、40% and 20%, degradation rate can reach at 51.2% 、42.9% 、39% 、31.5% and 24.9%,respectively.
