Gram-positive, motile rods, 0.5-1.0 x 2.0-4.0 μm, singly or in short chains. Produce
ellipsoidal, terminal spore in swollen sporangium.
Colonies are cream, smooth on nutrient agar and 1.5-3.0 mm in diameter after 3 days
at 30 ºC on TSA; not mucous on media containing 2% glucose or sucrose. Produces a
characteristic, fruity, volatile aroma on nutrient media.
Aerobic and anaerobic growth. Growth temperature 5-35 ºC, optimum 28 ºC. No growth
at 50 ºC.
Isolated from wheat roots and vegetable (pasteurized and chilled leek and courgette) purees. Nitrogen fixation bacteria (under
anaerobic conditions); nifH gene is present at least in the type strain.
Undetermined.
