[Free diaminopimelic acid of symbiotic bivalves].
Free amino acids were analyzed in tissues of symbiotic bivalves from hydrothermal vent sites at Galapagos rift, and cold-seeps in Japan trench and Barbados subduction area. Diaminopimelic acid (a fragment of the bacterial cell wall mureid complex) is, in some cases, one of the most abundant compounds. It's presence in the tissues of the bivalves is related to exchanges between host and symbionts. Diaminopimelate concentration differences among species may correspond to both taxonomic bacterial differences and different carbon translocation processes from bacteria to host. Variation among individuals may correspond to fluctuation of micro-environmental conditions.
