Lanzhou reach of the Yellow River is contaminated by heavy metals. Microbial research and remediation is still scarce. LZ-11 is the first strain that is able to resist and absorb Cd(II) isolated from this area and might be a good candidate for future cadmium bioremediation.

Staphylococcus aureus LZ-01 can resist 2 mmol l(-1) U(VI). It could adsorb more than 90% of the 2 mmol l(-1) U(VI) in 6 h. Uranium is precipitated with phosphorus on the surface of the cells. Phosphate promotes uranium adsorption in strain LZ-01, and its U(VI) adsorption capacity is related to its cell availability. These results indicate that the strain LZ-01 might be a potential candidate for remediation of nuclear waste when phosphate is added.
