Sphingomonas elodea ( Alemão )

fornecido por wikipedia DE

Sphingomonas elodea ist eine Bakterienart der Gattung Sphingomonas.

Merkmale

Sphingomonas elodea ist aerob, benötigt also Sauerstoff und besitzt ein Flagellum. Es bildet runde, gelb pigmentierte Kolonien.

Nutzung

Diese Spezies produziert Gellangummi, einen Lebensmittelzusatzstoff und Agarersatz für verschiedene klinisch-bakteriologische Medien und besonders wichtig für das Kulturwachstum von thermophilen Mikroorganismen in festen Medien.[1]

Als das Gellangummi-produzierende Bakterium 1978 von einem Team von Mikrobiologen der damaligen Kelco Division, Merck & Company (jetzt bekannt als CP Kelco) zum ersten Mal aus einem natürlichen Seerosenteich in Pennsylvania isoliert wurde, wurde es als Pseudomonas elodea klassifiziert. Das Bakterium wurde jedoch anschließend auf der Grundlage der aktuellen taxonomischen Klassifikation als Sphingomonas elodea neu eingruppiert.[2]

Sphingomonas elodea wandelt Maltodextrin (Oligosaccharid der Glucose) durch eine vermutlich exogen wirkende Glucosidase extern in Glucose um.[3]

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]
