Xanthobacter aminoxidans
is a Gram-negative pleomorphic and diazotrophic Knallgas bacillus that undergoes asymmetric budding of V-shaped branched cells during cell division. Like other
Xanthobacter
spp., cells are yellow from production of zeaxanthine dirhamnoside. We sequenced strain 14a
T
(= ATCC BAA-299
T
) and report a genome size of 5,829,486 bp with a G+C content of 67.9%.
