shiny on a clean surface

Yes. EMBA is a differential media for E.coli. E.coli will grow as dark blue/ purple colonies with green metallic sheen. Sometimes the green metallic sheen is more difficult to identify if you only are allotted a certain time to check results. Sometimes the presence of the green metallic sheen is for a fleeting time. Evidence of the green metallic sheen will be a glossy sheen to the inoculation streak. diana
One piece of evidence is that seismic waves pass through the Earth's core, indicating that it is not a solid mass. Additionally, the Earth's magnetic field is believed to be generated by the movement of molten iron within the outer core. Lastly, experiments conducted in labs using high-pressure and high-temperature conditions have simulated the Earth's core and showed that it behaves as a liquid.
