Phylum Proteobacteria, Class Betaproteobacteria, Order Burkholderiales, Family Alcaligenaceae, Genus Castellaniella,
Castellaniella daejeonensis Lee et al. 2010.
Gram-negative rods, 0.3-0.5 x 1.4-1.7 μm. Non-spore-forming. Motile.
Facultatively anaerobic. The optimum temperature for growth is 30 ºC. Optimum pH
for growth is 6.5-7.0.
Colonies on R2A agar plates for 2 days at 30 ºC were 0.5-2.0 mm in diameter,
circular, smooth, convex, shiny, transparent and yellowish. On R2A agar, LB agar, TSA
and nutrient agar the isolate was able to grow at 25-42 ºC, but not at 20 or 45 ºC. On
MacConkey agar, growth occurred at 30-42 ºC
Isolated from soil near an oil reservoir in Daejeon, South Korea.
