Ko.sa.ko'ni.a. N.L. fem. n.
Kosakonia
, named after Y. Kosako, for his contribution to bacterial taxonomy.
Pseudomonadota / Gammaproteobacteria / Enterobacterales / Enterobacteriaceae / Kosakonia
Species within the genus
Kosakonia
are primarily plant‐growth‐promoting bacteria, able to fix nitrogen and improve crop yield. However, several species have also been isolated from clinical samples and are thought to cause rare incidences of disease. Cells are Gram‐stain‐negative, facultatively anaerobic, and motile rods. Species are mesophilic, favoring growth temperatures of 30–35°C. Carbon sources such as glucose, cellobiose, fructose, galactose, gentiobiose, maltose, mannose, and
N
‐acetylglucosamine are readily assimilated. Species form a monophyletic clade when phylogenetic analysis is based on multilocus sequence analysis (MLSA) or whole‐genome sequences. The major fatty acids are C
16:0
and summed features 2 (iso‐C
16:1
and/or C
14:0
3‐OH) and 3 (C
