Ochrobactrum
From Wikipedia, the free encyclopedia
Ochrobactrum is a bacterial genus that belongs to Brucellaceae in the Rhizobiales. The genus has been described by Holmes in 1988 and Ochrobactrum anthropi was proposed as the type species of the genus. Further work led to the recognition of 16 other species,
- Ochrobactrum intermedium
- Ochrobactrum tritici
- Ochrobactrum grignonense
- Ochrobactrum gallinifaecis
- Ochrobactrum lupini
- Ochrobactrum oryzae
- Ochrobactrum cytisi
- Ochrobactrum pseudintermedium
- Ochrobactrum haematophilum
- Ochrobactrum pseudogrignonense
- Ochrobactrum rhizosphaerae
- Ochrobactrum thiophenivorans
- Ochrobactrum pituitosum
- Ochrobactrum guangzhouense
- Ochrobactrum ciceri
- Ochrobactrum pecoris.
The Ochrobactrum strains are all Gram-negative short rods, straight or slightly curved with one end flame shaped. The cells are approximately 0.6-1.2 to 2 μm in length. They are non-spore forming, strictly aerobic and non-fermentative.
The genomes of most Ochrobactrum species is complex with two independent circular chromosomes often associated to plasmids.
