Description

There is no specific in situ data for the genus. Both isolates are strict anaerobes and were isolated from thermophilic anaerobic digesters. They have a fermentative metabolism, utilising carbohydrates as well as proteinaceous carbon sources 4 3. Both species produce acetate, lactate and hydrogen as by-products of glucose fermentation. A. thermophila additionally produces small amounts of succinate and formate 4 3. A. thermophila has a putative cytochrome c nitrite reductase (NrfA) annotated in its genome 5. Although an ability for denitrification has not been demonstrated 4.
