Old synonym: Bacillus zeae Kampfer et al. 2017.
Description is based on a single isolate.
Gram-positive rods, 1.0 x 3.5 µm. Non-motile. Does not produce endospores.
Colonies on NA produce a beige colour and appear circular and slightly translucent.
Good growth occurs after 48h on NA, brain heart infusion agar, TSA and R2A agar at
20-30 ºC. Unable to grow at temperatures below 10 ºC or above 50 ºC. Optimum
temperature: 28-30 ºC. Cells grow at pH 6.0-10.0 (optimum pH 7) and in the
presence of 0-8.0% (w/v) NaCl (optimum: 3-5%, w/v, NaCl). Aerobic.
