Abstract
We describe a bacterium which demethoxylates O-methoxylated aromatic acids to give mixed volatile fatty acids. The cell wall composition and deoxyribonucleic acid-deoxyribonucleic acid homology data allow the organism to be included within the genus Eubacterium. Although the guanine-plus-cytosine content (47 mol%) is the same as that for Eubacterium limosum and the morphologies of the two organisms are similar, the new isolate differs in that it cannot utilize H2-CO2, methanol, or other one-carbon compounds or the amino acid isoleucine as growth substrates and in defined media requires acetate as a growth factor. The new species is named Eubacterium callanderi; the type strain is strain FD (= DSM 3662).
