Super-fungus developed to clean-up harmful toxins By By Tim Sandle Jul 17, 2012 in Environment A research team have discovered that a fungus that is common in polluted water produces environmentally important minerals as it reproduces. By utilizing this, scientists can develop a mineral that can be used to clean-up toxic residues. For the fungus, the superoxide helps its cells to divide. What the scientists have shown is that when the superoxide by-product is released into the environment it reacts with the element manganese. This reaction produces a highly reactive mineral. The mineral produced can be used to clean-up of toxic metals, according to The research findings were published by the Proceedings of the National Academy of Sciences (PNAS) in July. The research team was led by Colleen M. Hansel, Carolyn A. Zeiner, Cara M. Santelli, and Samuel M. Webb. Mn(II) oxidation by an ascomycete fungus is linked to superoxide production during asexual reproduction. PNAS, July 16, 2012 The research team, based at Harvard University , have identified that a fungus called Stilbella aciculosa can do something quite remarkable, according to the university’s research brief . The fungus, a member of the Ascomycete family, produces spores on stalks during reproduction. It is during this process that a chemical is produced called superoxide.For the fungus, the superoxide helps its cells to divide. What the scientists have shown is that when the superoxide by-product is released into the environment it reacts with the element manganese. This reaction produces a highly reactive mineral.The mineral produced can be used to clean-up of toxic metals, according to PhysOrg . The scientists believe that this mineral can be used for the cleaning of mines and other industrial processes where toxic contaminants, such as arsenic, cadmium, and cobalt, are a problem. These types of toxins, if they enter the water system, can prove to be particularly hazardous.The research findings were published by the Proceedings of the National Academy of Sciences (PNAS) in July. The research team was led by Colleen Hansel , a faculty associate professor of environmental microbiology at the Harvard School of Engineering and Applied Sciences (SEAS).
