| Popis: | Summary Analysis of the lipids of seven species of Micromonospora showed the constant presence of five phospholipids and three glycolipids. The phospholipids were identified as cardiolipids, phosphatidylethanolamine, phosphatidyl-inositol, mannosides of phosphatidyl-inositol, and possibly lysocardiolipids. The glycolipids were monoglucosyl-diglycerides, diglucosyldiglycerides (with a small amount of galactosyl-glucosyl-diglycerides) and esters of fatty acids and trehalose. The simultaneous presence of glucosyldiglycerides and trehalose esters might be specific of the genus Micromonospora . In the seven species studied, a large amount of the total fatty acids(obtained by direct saponification of the cells) consisted of iso and anteiso fatty acids. Three groups could be distinguished, having respectively iso -C 15 , iso -C 16 and n -C 17 fatty acids as the main members. A monounsaturated C 17 acid has been identified as hepatadec-9,10-enoic acid. |
