Increased rate of global warming as well as uncontrolled growth of pollution is one of biggest task to resolve for all of us. As we all know at least drop of water is important to exist our presence in the earth. According to sources, UN Water statistics,
The total volume of water on Earth is about 1.4 billion km3. The volume of freshwater resources is around 35 million km3, or about 2.5 percent of the total volume. Of these freshwater resources, about 24 million km3 or 70 percent is in the form of ice and permanent snow cover in mountainous regions, the Antarctic and Arctic regions.
At this negative stage research on bacteria may provide hope for treating polluted for and making them drinkable.
Researcher from Penn State College of Engineering defines Phosphorous is one of important mineral nutrients applied to crop field regularly. And Excess quantity of Phosphorous is run off through rain water into Lake Stream which is harmful to watery habitat animals and even human too.
Researchers confirmed Phosphorous amount about less than 0.02 parts per million is good for water systems and presence is water ecosystem promotes the growth of Algae which in turn help full for watery animals and excess content of Phosphorous causes over growth of algae results in water blooms and make polluted water.
"Historical applications of manure and fertilizer have built up phosphorus levels in many of our agricultural soils — often times above and beyond what's needed by crops — which then renders the excess phosphorus susceptible to loss when microbial processes and other hydrological and biogeochemical factors come into play," said Anthony Buda, a research hydrologist at the U.S. Department of Agriculture (USDA) Agricultural Research Service.
"We are trying to understand two groups of bacteria that could affect whether phosphate is retained in the soil or becomes mobile and gets into the water," said John Regan, professor of environmental engineering at Penn State and lead project director.
Certain microbes play an important role in Phosphorous mobility in soils, "Microbes that affect phosphorus mobility are known to exist and are being used in some wastewater treatment plants to reduce the amount of phosphorus in water leaving the plant," said environmental engineering graduate student Miranda Stockton.
At the results researcher explained by monitoring the activity of concern bacteria important when and how phosphorous controlled in soils then can design model to treat polluted water.
