Description

Bacteria of the genus Conexibacter are characterized as small rods with width of 0.6-0.7 µm and length of 0.9-1.2 µm. They are Gram-positive, aerobic, non-sporulating and are motile by characteristic long peritrichous flagella. The type strain of this genus is Conexibacter woesei named in honor of Carl R. Woese, a pioneer with this work on the use of 16S rRNA for phylogenetic analysis. C. woesei was isolated from forest soil in Gerenzano, Italy and grows optimally at pH 7-7.5 and at 28-37ºC.

The genus Conexibacter was first developed in 2003 with the discovery of the type strain C. woesei. In 2012 a second species, Conexibacter arvalis, was isolated from Japan field soil. Both cultures are available in pure culture. The genus is known as a very deep branch of the phylum Actinobacteria having only a 90% similarity to their next closest genus Thermoleiphilum, and being only 83.8% similar to the well known genus Rubrobacter, which contains species known to be the only thermophiles that are radiation resistant.
