The invention belongs to the field of environment treatment and discloses a heavy metal tolerant enterobacter and a heavy metal removal effect thereof. The bacterium is a plant endogenous Enterobactersp. YG-14 which is separated from a populus tremula root planted in a heavy metal mine. The bacterium has a high tolerance level for type heavy metals such as lead, zinc and cadmium in the south areaof China, has high removal efficiency upon zinc and cadmium in water solutions, and has a good removal effect on the heavy metal lead of different concentrations after being compounded with populus tremula charcoal. As a novel microorganism resource, YG-14 has great development potential in biological treatment on heavy metal pollution.
