Gram-negative straight rods. Usually non-motile. Nonspore-forming.
No production of fluorescent pigment or other pigments. Grows on blood agar at 30
ºC but not on Drigalski agar (may grow weakly), on blood agar at 37 ºC or on nutrient
agar at 42 ºC. Haemolysis of horse blood is not observed. No growth is observed on
cetrimide agar,on 10% lactose medium, in the presence of acetamide or in the
presence of 0.5, 1.5, 3.0, 4.5 or 6.0% NaCl (with few exceptions).

Isolated from moss (Sphagnum rubellum, Sphagnum palustre and Aulacomnium palustre) gametophytes in northern Germany and
from agricultural soil (UK) and grassland (The Netherlands). Most strains are resistant to penicillin. Plant-growth promoting.

Undetermined. May have antagonistic activity against Verticillium dahliae, Rhizoctonia solani, Candida albicans, Xanthomonas
campestris, Staphylococcus aureus, Erwinia carotovora subsp. atroseptica and Phytium ultimum.

Positive results for alkaline and acid phosphatase, catalase, esterase C4 (weak reactions occur), leucine arylamidase, oxidase and
phosphoamidase.
Can assimilate (some strains may give weak reactions): D-glucose, L-arginine, L-arabinose, D-mannose, D-mannitol,
N-acetyl-D-glucosamine, D-gluconate, caprate, L-malate, citrate, phenylacetate (most strains), DL-lactate and DL-lactate with
methionine.
Negative results for arginine dihydrolase, amylase, DNase, alpha-fucosidase, gelatinase, alpha-galactosidase, beta-glucuronidase,
alpha- and beta-glucosidase, N-acetyl-beta-glucosaminidase, alpha-mannosidase, H2S production, indole production, nitrate
reduction to nitrite, denitrification, lysine decarboxylase, lipase C14, ornithine decarboxylase, urease (most strains), valine
arylamidase, cystine arylamidase, trypsin and chymotrypsin.
No acid production is observed in O/F medium with D-glucose (except for two isolates that yield weak growth), maltose, adonitol,
D-fructose or D-xylose as carbon source.
No assimilation of trehalose (weak positive reaction may occur), DL-norleucine, maltose or sucrose.
Variable results for esculin hydrolysis, ester lipase C8, beta-galactosidase (ONPG), Tween 80 hydrolysis (usually positive) and
assimilation of adipate.
