This is scientific Americans 60 second science,I'm Cynthia Graber.This will just take a minute.A coal mine can decrease the local environment but a Fungi 1 may indivertantly help cleanup the mine with its own waste products. Researchers worked with the Fungi called Stillbella SecureLosa as it makes balls and also produces superoxide that's a highly reactive kind oxygen when the release superoxide bombs into the mineral manganese environment it makes minerals that much more reactive itself.The paptop manganese then grasps and holds variety of toxic 2 metals another substances that need to be cleanup and taken out of coal mine drainage water.The research led by Colin Hanso of Harvard and Wooze Hole Ocean graphic 3 Institution appears in the procceedings of national academy sciences.It's been known the virus bacteria and Fangi can help environmental remediation.The new research shows that production of the vital forms of manganese requires of the Fungi and bacteria be actively 4 produced superoxides,so creating conditions that encouraged organism to make the superoxide could be the first step in the pasthway by which the help manganese to literally 5 do the dirty work and make some toxic sides a lot cleaner.Thanks for the minute for scientific Americans 60 second science,I'm Cynthia Graber.
