Abstract

Fatty acid and aldehyde compositions of phospholipids from Selenomonas ruminantium cells, grown under various nutritional conditions, were examined. When the cells were grown in a lactate medium or in a glucose medium supplemented with odd-numbered volatile fatty acid (valerate or heptanoate), fatty acid side chains in phospholipids were composed mainly of C15:0 and C15:1. The major fatty aldehydes in plasmalogens were C17:1 and C15:0. When cells were grown in a glucose medium supplemented with even-numbered volatile fatty acid (butyrate, caproate, or caprylate), the major fatty acids in phospholipids were C16:1 and C14:0. The main fatty aldehyde in plasmalogens was C16:1. 14C-Valerate or caproate, supplemented to the glucose medium, was incorporated into the aldehyde side chains of plasmalogens.
