NewsRx -- A report, ‘Nonmagnetotactic multicellular prokaryotes from low-saline, nonmarine aquatic environments and their unusual negative phototactic behavior,’ is newly published data in Applied and Environmental Microbiology. “Magnetotactic multicellular prokaryotes (MMPs) are unique magnetotactic bacteria of the Deltaproteobacteria class and the first found to biomineralize the magnetic mineral greigite (Fe(3)S(4)). Thus far they have been reported only from marine habitats,” scientists writing in the journal Applied and Environmental Microbiology report.
