Efficient Copper Biosorption by Rossellomorea sp. ZC255: Strain Characterization, Kinetic–Equilibrium Analysis, and Genomic Perspectives

mycolabadmin

Scientists found that a bacterium called Rossellomorea sp. ZC255 can efficiently remove copper pollution from water. The strain works best at neutral pH and room temperature, achieving a removal capacity of 253.4 mg of copper per gram of bacterial biomass. By studying the bacteria’s structure and genes, researchers discovered that the removal happens through both surface binding and internal accumulation mechanisms, making it a promising eco-friendly solution for treating polluted water.

Shotgun metagenomics analysis indicates Bradyrhizobium spp. as the predominant genera for heavy metal resistance and bioremediation in a long-term heavy metal-contaminated ecosystem

mycolabadmin

Scientists collected soil samples from a contaminated nuclear facility and used advanced DNA sequencing techniques to identify which bacteria live in the polluted soil. They found that a bacterium called Bradyrhizobium dominates the soil and appears to be naturally resistant to heavy metals like uranium and nickel. This suggests that this specific bacterium could be used to help clean up and restore contaminated environments.
