Metabolite concentrations in electrically stimulated lugworms arenicola marina

Metabolite concentrations in electrically stimulated lugworms arenicola marina

Comparative Biochemistry & Physiology B 67(1): 187-190

The concentrations of lactate, succinate, alanine, aspartate, acetate and propionate in the lugworm A. marina were measured after 1, 2.5 and 12 h of continuous electrical stimulation under aerobic and anaerobic conditions. A continuous increase of the concentrations of alanine and acetate, and a decrease of aspartate occurred during the first 2.5 h of electrical stimulation. A marked rise of succinate and propionate was observed only in experiments lasting longer than 2.5 h. No changes were detected in the concentrations of lactate. Under anoxia the metabolites accumulated at significantly higher rates than under aerobic conditions.
