residui Vaz-Moreira, Figueira, Lopes, Pukall, Sproer, Schumann, Nunes and Manaia 2010.
Gram-variable, motile (polar flagella) rods, 0.5 x 1.4-1.6 µm. Spore is oval, centrally
positioned, swelling the sporangium.
Colonies on PCA (Plate Count Agar) after 2 days of incubation are translucent, irregular.
Aerobic growth; not anaerobic. Growth temperature 25-50 ºC, optimum 37 ºC. Can grow
in 2%, but not in 5% NaCl media. Grow at pH 7-9.
Isolated from municipal urban waste compost.
Resistant to cephalothin, ceftazidime, colistin sulphate and streptomycin. Susceptible to meropenem, amoxicillin, gentamicin,
ciprofloxacin, sulfamethoxazole/trimethoprim, tetracycline, ticarcillin and sulfamethoxazole.
Undetermined.
