Anti-Therapeutic Action: cadmium toxicity

Multi-metal-resistant Staphylococcus warneri strain TWSL_1: revealing heavy metal-resistant genomic features by whole-genome sequencing and analysis

mycolabadmin

Scientists discovered a special type of bacteria called Staphylococcus warneri TWSL_1 from textile factory wastewater that can survive and remove dangerous heavy metals like lead, cadmium, and copper from contaminated water. By analyzing the bacteria’s complete genetic code, researchers identified specific genes that help this bacteria resist and detoxify these toxic metals. This discovery suggests the bacteria could be used as a natural cleaning solution to remove heavy metal pollution from industrial wastewater, offering an eco-friendly alternative to current cleanup methods.

Impact of energy metabolism pathways in promoting phytoremediation of cadmium contamination by Bacillus amyloliquefaciens Bam1

mycolabadmin

Researchers developed genetically modified bacteria (Bacillus amyloliquefaciens) that produce more energy to better survive in cadmium-contaminated soil. These enhanced bacteria can then help tomato plants absorb and remove cadmium pollution from the soil more effectively. The best-performing modified strain increased cadmium accumulation in tomatoes by nearly 1.9 times compared to the original bacteria, offering a promising biological solution for cleaning contaminated agricultural soils.

Bioaccumulation and physiological changes in the fruiting body of Agaricus bisporus (Large) sing in response to cadmium

mycolabadmin

This research shows that button mushrooms (Agaricus bisporus) can absorb and accumulate harmful cadmium from contaminated soil. When exposed to cadmium stress, the mushrooms increase their protective chemical defenses, including antioxidant enzymes and organic acids, to survive the toxic conditions. The study demonstrates that these edible mushrooms could potentially be used as a practical and cost-effective method to clean up cadmium-polluted soils.
