Sphingomonas phyllosphaerae

Sphingomonas phyllosphaerae is a species of bacterium. It was first isolated from the phyllosphere of a leguminous tree, Acacia caven, in central Argentina. It is Gram-negative, strictly aerobic, rod-shaped and motile. Its type strain is FA2(T) (=LMG 21958(T)=CECT 5832(T)). Sphingomonas phyllosphaerae tested negative for amylase activity, indicating its inability to digest starches. This aligns with many other Sphingomonas species . Other Sphingomonas species display motility by polar flagellation. Citrate testing shows that citrate is not a carbon source for most Sphingomonas species . There are Sphingomonas species that show resistance to many different antibiotics. In the lab, this aligns with Sphingomonas and its ability to resist antibiotics . Sphingomonas species are known to be cold-tolerant, which means the optimal temperature for growth is around 4 degrees Celsius
