Response mechanism of extracellular polymers in the remediation of chromium pollution by carbonate mineralizing bacteria

mycolabadmin

Certain bacteria can help clean up chromium pollution by producing protective coatings made of sugar and protein molecules. When exposed to high levels of chromium, these bacteria produce more of these protective coatings, which trap and neutralize the toxic metal. The coating changes its composition to better bind chromium, and the protein structure becomes more porous to catch more metal. This research shows how nature can be used to clean up contaminated environments.

Isolation and characterization of thermotolerant hydrocarbon degrading bacteria which sustained the activity at extreme salinity and high osmotic conditions

mycolabadmin

Scientists isolated two special bacteria from highly polluted oil fields in Iran that can degrade diesel and survive in extreme conditions. These bacteria tolerate very salty soils, high temperatures up to 50°C, and drought stress that would kill ordinary bacteria. This discovery is important because oil-contaminated areas often have these harsh conditions, and using these adapted bacteria could help clean up oil spills in difficult environments like Middle Eastern oil fields.
