Metal Taste Goood…Nom, Nom, Nom

ResearchBlogging.orgNew research out in Microbiology reports on a strain of the bacteria Brachybacterium (Mn32) that can remove toxic metal manganese from solution by oxidizing in into a manganese oxide.  This oxide then can absorb zinc and nickle ions three to four more times efficiently than that manganese oxide produced chemically.  The next step is to move tackling the hurdles to use such a process and bacteria in heavy metal bioremediation.  The bacteria were originally isolated in from sediment samples taken in the deep Pacific Ocean.  Just another way that deep-sea organisms may save your tail.

Craig McClain is the Assistant Director of Science for the National Evolutionary Synthesis Center, created to facilitate research to address fundamental questions in evolutionary science. He has conducted deep-sea research for 11 years and published over 40 papers in the area. He has participated in dozens of expeditions taking him to the Antarctic and the most remote regions of the Pacific and Atlantic. Craig’s research focuses mainly on marine systems and particularly the biology of body size, biodiversity, and energy flow. He focuses often on deep-sea systems as a natural test of the consequences of energy limitation on biological systems. He is the author and chief editor of Deep-Sea News, a popular deep-sea themed blog, rated the number one ocean blog on the web and winner of numerous awards. Craig’s popular writing has been featured in Cosmos, Science Illustrated, American Scientist, Wired, Mental Floss, and the Open Lab: The Best Science Writing on the Web.
