Thiovulum majus

Thiovulum majus is a kind of bacteria. It is 600 micrometers per second is one of the most rapidly advancing bacteria. You will be provided to the Department of proteobacteria, the Gram stain falls, as with all members of this class, negative. It is the only species of the genus Thiovulum. The prefix of the name thios - is Greek and stands for sulfur, ovum is Latin and means egg: The bacterium is ovoid and is able to oxidize hydrogen sulfide (H2S ) and use it as an energy source for metabolism.

Features

Thiovulum majus is microaerophilic, that is, it tolerates only a low oxygen concentration. The cells are round with a diameter of 5-25 microns and are peritrich ( all around) flagella. It occurs in seawater and freshwater. The bacterium belongs to the sulfur-oxidizing bacteria, to oxidize hydrogen sulphide to elemental sulfur (S), the sulfur is deposited in the form of globules, small beads within the cell. This sulfur is an energy reserve when no hydrogen sulfide is available, the bacterium can be obtained by the oxidation of sulfur to sulphate energy. It is thus chemolithotroph, i.e. for energy it requires no organic substances.
