Fungus Among Us: Invisible Micropollutants Invade Crops, Water Supply

Summary:
They're here, there, and everywhere: Toxins produced by a common fungus are spreading beyond food crops and invading the environment, including water supplies, with unknown consequences, researchers in Switzerland report. Their study reveals a need for stronger monitoring and control of these overlooked micropollutants.

They're here, there, and everywhere: Toxins produced by a common fungus are spreading beyond food crops and invading the environment, including water supplies, with unknown consequences, researchers in Switzerland report. Their study reveals a need for stronger monitoring and control of these overlooked "micropollutants."

The contaminants are members of a larger family fungal-produced toxins called mycotoxins. In the report, Thomas Bucheli and colleagues note that scientists have studied two of the most common mycotoxins -- deoxynivalenol and zearalenone -- in food and animal feed products for decades. However, scientists know very little about the distribution of these toxins elsewhere in the environment.

In the new study, the researchers exposed a winter wheat field to Fusarium graminearum, a major fungal source of deoxynivalenol and zearalenone, and subsequently monitored these toxins in the field's drainage water before, during and after harvest. Using high-tech lab instruments, they found that levels of these toxins increased significantly after harvest. Levels of deoxynivalenol, for instance, rose by almost 4,000-fold. Traces of these toxins were also found in a number of Swiss rivers, they note.

The study "Fusarium Mycotoxins: Overlooked Aquatic Micropollutants?" is scheduled for the Feb. 13 issue of ACS' Journal of Agricultural and Food Chemistry. http://dx.doi.org/10.1021/jf073082k

Deep Sea 'mushroom' Could Be Early Branch on Tree of Life

Reuters - Innovations Video Online (Oct. 24, 2014) Miniature deep sea animals discovered off the Australian coast almost three decades ago are puzzling scientists, who say the organisms have proved impossible to categorise. Academics at the Natural History of Denmark have appealed to the world scientific community for help, saying that further information on Dendrogramma enigmatica and Dendrogramma discoides could answer key evolutionary questions.
