Abstract: 

Pae'no.chro.bac'trum L. adv. paene, nearly, almost; N.L. neut. n. Ochrobactrum, a bacterial genus name; N.L. masc. n. Paenochrobactrum, almost Ochrobactrum.

Proteobacteria / Alphaproteobacteria / Rhizobiales / Brucellaceae / Paenochrobactrum

The genus Paenochrobactrum in on the basis of the 16S rRNA gene sequence phylogeny placed into to the family Brucellaceae most closely related with the genera Pseudochrobactrum, Ochrobactrum, and Brucella. Cells are nonmotile, non-spore-forming rods. Gram-staining negative and oxidase-positive, showing an oxidative metabolism. The polyamine pattern is composed of the major compound putrescine and moderate to high amounts of spermidine, while sym-homospermidine is lacking. Small amount of 1,3-diaminopropane and spermine can be detected. The polar lipid profile consists of the major compounds phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, phosphatidylcholine, phosphatidylmonomethylethanolamine, and unknown aminolipid AL1 and as moderate or minor compounds unknown polar lipid L1 and L2. In addition, a specific stretched aminolipid is detectable. The quinone system is dominated by ubiquinone Q-10, and minor amounts of Q-8, Q-9, and Q-11 can also be detected. Major fatty acids are C_18:1 ω7c and C_19:0 cyclo ω8c. The genomic G+C content is between 48.5–49.7 mol%. The phylogenetic position of the genus is supported by recA and RecA based phylogenetic analysis. Currently three species are assigned to the genus.
