Sphingomonas elodea is a species of bacteria in the genus Sphingomonas .

features

Sphingomonas elodea is aerobic , so it needs oxygen and has a flagellum . It forms round, yellow pigmented colonies.

use

This species produces gellan gum , a food additive and agar substitute for various clinical-bacteriological media and particularly important for the culture growth of thermophilic microorganisms in solid media.

When the gellan gum-producing bacterium was first isolated from a natural lily pond in Pennsylvania in 1978 by a team of microbiologists from what was then the Kelco Division, Merck & Company (now known as CP Kelco) , it was classified as Pseudomonas elodea . However, the bacterium was subsequently reclassified as Sphingomonas elodea based on the current taxonomic classification .

Sphingomonas elodea converts maltodextrin ( oligosaccharide of glucose ) externally into glucose by a presumably exogenous glucosidase .
