Gram-negative short rods, mean 0.5-1.5 μm. Non-motile (or weak motility).
Colonies are opaque, ivory, smooth, circular, raised and 1.0-2.0 mm in diameter after
cultivation at 37 ºC for 3 days on TSA medium. Growth occurs at 15-42 ºC (optimally at
37 ºC, in presence of 0-15% (w/v) NaCl (optimally in 1-2% NaCl) and at pH 5.0-9.0
(optimally at pH 6.0). Facultatively anaerobic.
Isolated from larval gut of Hermetia illucens (Diptera: Stratiomyidae).
Undetermined.
