Sphingomonas elodea is a species of bacteria in the genus Sphingomonas.
This species is important to humans due to the fact that it produces gellan gum, a suitable agar substitute as a gelling agent in various clinical bacteriological media[2] and especially important for the culture growth of thermophilic microorganisms in solid media.[3] When the gellan gum-producing bacterium was first isolated from a natural lily pond it was classified as Pseudomonas elodea based on the taxonomic classification of that time.[4] However, the gellan gum-producing bacterium was subsequently re-classified as Sphingomonas elodea based on the current taxonomic classification.[5]
Sphingomonas elodea metabolizes maltodextrin (oligosaccharides of glucose) externally into glucose by the putative exo-acting glucosidase.[6] Sphingomonas elodea utilizes the Entner-Doudoroff pathway for glucose metabolism.[5]
