Gram-positive cells. Non-motile.
Colonies on yeast extract-peptone media are either pearl-gray/white or show a yellow,
nondiffusible pigment depending on strain. Growth on nicotine mineral salts-yeast
extract agar is abundant with production of a deep blue, diffusible pigment which
turns reddish or yellow-brown in older cultures. Grows at 20 and 37 ºC; optimum
growth temperature is 28 ºC. Variable growth at 42 ºC. Grows in 0-10% NaCl. Nicotine
blue is produced from nicotine. Aerobic.

Isolated from cured tobacco leaves and associated air by enrichment in nicotine-mineral salts-yeast extract medium.

Positive results for citrate, DNase, beta-galactosidase, alpha-glucosidase, gelatin hydrolysis, nitrate reduction, starch hydrolysis,
tyrosine hydrolysis, acid production from L-arabinose, galactose, glucose, inositol, lactose, mannitol (contradictory reports), maltose,
rhamnose, andd trehalose. Urea is formed from creatinine and uric acid.
Can utilize L-arginine, L-asparagine, L-histidine, L-leucine, L-arabinose, D-galactose, D-glucose, L-rhamnose, D-ribose, D-xylose,
butanediol, histidinol, inositol, malonate, sorbitol, lactose, xylitol, and sucrose. Assimilates citric acid, formic acid, propionic acid, and
uric acid.
Negative results for alkaline phosphatase, esterase C4, esculin hydrolysis, beta-glucosidase, pyrrolidonyl peptidase and
N-acetylglucosaminidase.
No utilization of maltose. No ssimilation of adipic acid, benzoic acid, glutaric acid, malonic acid, or pimelic acid.
Variable results for Tween 80 hydrolysis.
