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

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.

The ATO gene family governs Candida albicans colonization in the dysbiotic gastrointestinal tract

mycolabadmin

This study shows that the fungus Candida albicans uses a family of protein transporters called ATO to absorb acetate, a fatty acid produced by gut bacteria. When mice were treated with antibiotics that killed their beneficial bacteria, C. albicans could colonize their guts better if it had working ATO transporters. The research reveals that fungi have evolved special systems to take advantage of nutrients left behind when the normal gut bacteria are disrupted, which helps explain why fungal infections are more common after antibiotic use.
