Firmicutes / “Clostridia” / Clostridiales / Veillonellaceae / Mitsuokella
Gram‐stain‐negative
,
obligately anaerobic
,
non‐spore‐forming
,
nonmotile rods
. Stout rods of regular shape with rounded ends.
Fermentative metabolism
. Growth is enhanced by glucose or other fermentable carbohydrates.
Major end products from glucose fermentation are acetate
,
lactate and succinate
. No copious gas formation from glucose. Gelatinase and catalase absent; amylase present. Indole‐negative. Nitrate is reduced to nitrite.
DNA G+C composition is 55.9–58.2 mol% (
T
m
). On the basis of 16S rRNA gene sequences,
Mitsuokella
belongs to the
Sporomusa
branch of the
Clostrium
subphylum of the
Firmicutes
where it is closely related to
Selenemonas ruminantium
(Lan et al., 2002b; Willems and Collins, 1995b).
