Fatty Acid Composition of Propionibacterium propionicum (Arachnia propionica)

Abstract
The cellular fatty acids of Arachnia propionica are largely 13-methyltetradecanoic acid (Ci15:0) and 12-methyltetradecanoic acid (Ca15:0); thus, the fatty acid pattern of this organism resembles the pattern found in propionibacteria. This finding supports the transfer of members of the genus Arachnia to the genus Propionibacterium.
