Yeasts can not only send bread brewed beer, but also effectively remove lead pollution in water

Science Fiction Network June 24 (Qin Yingying) Due to mining activities and electronic waste emissions, heavy metal traces found in water resources pose a threat to the world. When the heavy metal content in drinking water is low, the traditional processing process cannot remove the toxic heavy metals from the drinking water in a resource -saving manner. However, a new study shows that a rich waste from brewing can filter the trace lead in the water.

Recently, research teams from the Massachusetts Institute of Technology, Brown University, Wellsley College, Nanyang University of Technology and the National University of Technology of Athens found that non -active yeast can be used as a cheap, rich and simple material to effectively remove drinking water Lead pollution in supply.

Heavy metals are highly water -soluble and non -biological degradation. When it is released into the water body, it often exists indefinitely. Lead is one of the most widely used heavy metals. In the past ten years, its output has increased by about 20%, and by 2020, global output will reach about 11.7 million tons. Lead toxicity is very high, and even under the trace concentration, it will have harmful effects on human organs and tissues. It may enter drinking water due to improper water treatment, or due to the chemical reactions containing lead components in the water distribution system.

The yeast for winemaking can be effectively removed from the water through the water of the rapid transmission process called biological adsorption. A absorption of milligrams of lead.

The lead in yeast adsorption water has opened up new opportunities for the treatment of advanced water for emerging pollutants for environmental protection and rich biomass materials.
