The archaeon Sulfolobus can be found near geysers like this one in Yellowstone
Dennis Grogan isolates cultures in the lab
A study of microbes that thrive in hot, acidic conditions has overturned a long-held view that species of micro-organisms do not differ by geographic location like other forms of life. The research by the University of Cincinnati and the University of California-Berkeley has just been published online by the journal Science.
When it comes to plant life and animal life, a species usually shows genetic differences in different parts of the world. For the tiny form of life known as micro-organisms, the opposite has been considered to be true – they don’t tend to differ by geographic location. That long-held view has been convincingly overturned in a study by University of Cincinnati and University of California, Berkeley, researchers focusing on a form of life that flourishes in extremely hot conditions.
Co-authors Dennis Grogan of the University of Cincinnati and Rachael J. Whitaker and John W. Taylor of Berkeley provide the most comprehensive proof to date that at least one species of micro-organism in different parts of the world does have genetic differences, if you look close enough. Whitaker, the principal author, focused on the archaeon Sulfolobus, found in acidic hot springs and flourishing at temperatures from 140-180 degrees Fahrenheit. She drew the vast majority of samples for her analysis from archives developed and stored at the University of Cincinnati Department of Biological Sciences under the leadership of Grogan. Whitaker analyzed the DNA of some 78 cultures from the United States, Eastern Russia and Iceland.
