Mycoplasmas - Stealth Pathogens. By Leslie Taylor January, 2001. Mycoplasmas are a specific and unique species of bacteria - the smallest free-living organism known on the planet. The primary differences between mycoplasmas and other bacteria is that bacteria have a solid cell-wall structure and they can grow in the simplest culture media.
Definition of titanium. : a silvery-gray light strong metallic element obtained from ilmenite and rutile and used especially in alloys and combined in refractory materials, pigments, and coatings â see element table.
Titanium is a chemical element with symbol Ti and atomic number 22. It is a lustrous transition metal with a silver color, low density and high strength. It is highly resistant to corrosion in sea water, aqua regia and chlorine.Titanium was discovered in Cornwall, Great Britain, by William Gregor in 1791 and named by Martin Heinrich Klaproth for the Titans of Greek mythology.t is a strong metal with low density that is quite ductile (especially in an oxygen-free environment), lustrous, and metallic-white in color. The relatively high melting point (more than 1,650 Â°C or 3,000 Â°F) makes it useful as a refractory metal.
