Flectobacillus major is a type of bacteria . It belongs to the family Cytophagaceae . The generic name is derived from the Latin word "flecto" (to curve) and the Latin word "bacillus" (rod) and refers to the cell shape . The species name is derived from the Latin word "major" (larger).
Appearance
The cells of the species are rod-shaped, curved to various degrees. The shape is often like the letter C or like a horseshoe. An apparently ring-shaped cell can appear, with the two ends overlapping. These rings have a diameter of approx. 5–10 µm. The normal cell size when there are no overlaps is in the range of 0.6-1.0 µm x 1.5-5.0 µm. Sometimes longer cell shapes appear.
Helical cells can also be seen in young colonies (24-48 hours). If the cultures are a little older, screw-like thread shapes also rarely appear, the length can be a few 10 µm. Rings are rarely formed in older cultures. The diameter of the cultures can be up to 5 mm. The edge is smooth, the colony is transparent. The color of the colony is light pink.
Growth and metabolism
They are chemo-organotrophic bacteria. They are strictly aerobic , so they rely on oxygen for breathing . A respiratory metabolism, i.e. breathing, takes place. The oxidase test is positive. Good growth occurs at 24 ° C.
Systematics
Flectobacillus major belongs to the family Cytophagaceae, which in turn belongs to the order Cytophagales . The division are the Bacteroidetes .
ecology
Flectobacillus major occurs in soil and fresh water.
