Description

Strictly anaerobic, thermophilic and syntrophic bacteria with rod shaped morphology in pure culture 1. The sole species of the genus Gelria glutamica is a strictly syntrophic, glutamate-degrading organism, which forms a syntrophic association with a hydrogenotrophic methanogen, Methanobacterium thermoautotrophicus 1. In co-culture, these bacteria can utilise glutamate, a-ketoglutarate, proline, casamino acids and a number of sugars under thermophilic conditions 1. Products of glutamate and proline oxidation are propionate, H2, NH4+ and CO2, while sugars are converted to acetate, propionate, CO2 and H2 1. Nothing is known about the genus' physiology in situ.
