Velick and Anderson (1944) isolated an unidentified acid which they called phytomonic acid and which later was shown by Hofmann and Tausig (1955b) to be identical with lactobacillic acid. A more recent investigation of the lipids of A. 5% total free lipids of which 5% were neutral lipid (about half being coenzyme Q, the remainder glycerides and fatty acids); the phosphatides contained mostly phosphatidylethanolamine together with about 15% of lecithin. Law et al. (1963) have demonstrated the presence in this organism of phosphatidyl-N-methylethanolamine and phosphatidylΝ,Ν-dimethylethanolamine in addition to lecithin and phosphatidylethanolamine.
Natto have been investigated by Akashi and Saito (1960) and Saito (1960a,b), chiefly for their fatty acids. These bacteria contain about 3 % of extractable lipids, of which about two thirds is acetone-soluble (neutral lipids) and one third acetone-insoluble (phosphatides). ) amounting to 3 % of cell dry weight was found previously in B. subtilis (Akashi, 1940). The fatty acids of these bacilli consist largely of a branched-Ci5 acid together with small amounts of myristic, palmitic, and branched-Ci7 acids (Saito, 1960a,b).
Coli (Marr and Ingraham, 1962) and B. subtilis (Gau- 45 Bacterial Lipids ghran, 1947b), but not for S. marcescens (Bishop and Still, 1963b), nor for thermophiles, which are adapted to high temperatures. Gaughran (1947b) found that the lipids of a stenothermophilic bacillus were strikingly constant in quantity and degree of unsaturation at temperatures above its optimum, but the lipids of Bacillus stearothermophilus spores (a thermophile having 3-5% lipids) appear to show an increase in unsaturation at high temperatures (Long and Williams, 1960).
