Thiovulum majus is a type of bacteria . It is one of the fastest moving bacteria at 600 microns per second. It becomes the Department of proteobacteria found that Gram staining is negative. It is the only species in the genus Thiovulum . The prefix of the name thios- is Greek and stands for sulfur, ovum is Latin and means egg: The bacterium is egg-shaped and is ableto oxidize hydrogen sulfide (H 2 S)and use it as an energy source for metabolism.
features
Thiovulum majus is microaerophilic , i.e. H. it only tolerates a low concentration of oxygen. The cells are round with a diameter of 5 to 25 micrometers and are peritrich (all around) flagellated. It occurs in sea and fresh water. The bacterium is one of the sulfur oxidizing bacteria , it oxidizes hydrogen sulfide to elemental sulfur (S), the sulfur is deposited in the cell in the form of globules, small spheres. This sulfur is an energy reserve, if no hydrogen sulfide is available, the bacterium can gain energy by oxidizing the sulfur to sulfate . It is thus chemolithotrophic , i.e. H. it does not require any organic substances to generate energy.
