Marinilabilia salmonicolor is a type of bacteria . It is the only species in the Marinilabilia genus . The generic name is derived from the Latin adjective "marinus" (sea) and the Latin adjective "labilis" (sliding), it is a marine organism that moves by sliding. The species name M. salmonicolor is derived from the Latin word "salmo", which means "salmon pink", and the Latin "color", the name refers to the color of the colonies .

Appearance

The cells of Marinilabilia salmonicolor are straight, thin rods . The ends are rounded or slightly pointed, usually 0.3 to 0.5 µm wide and between 2 and 50 µm, usually around 10 to 20 µm, long. They are movable by sliding . The gram test is negative. Marinilabilia salmonicolor is facultatively anaerobic , which means that it occurs in areas that are more oxygen-free, but can tolerate oxygen as it grows. The color of the colonies is salmon red to pink. Spores are not formed. The catalase test is positive.

Growth and metabolism

Marinilabilia salmonicolor can use both fermentation and respiration for chemo-organotrophic metabolism. The products of fermentation of glucose are acetic acid , succinyl acid (succinic acid), propionic acid , lactic acid , formic acid , carbon dioxide (CO ₂ ), hydrogen (H ₂ ) and small amounts of ethanol . The species needs sodium chloride (NaCl) for growth. The optimal temperature for growth is between 28 and 37 ° C, the optimal pH value is 7.

Systematics

Marinilabilia salmonicolor is the only species of the genus and is placed in the family Marinilabiliaceae in the order Bacteroidales in the division of the Bacteroidetes . The species Marinilabilia agarovorans was dissolved after phylogenetic investigations and added to the species Marinilabilia salmonicolor .
