“…Some authors found the following composition of fatty acids in I. galbana: 11.1% C14:0, 15.5% C16:0, 1.1% C16:1, 2.0% C18:0, 28.6% C18:1, 7.4% of C18:2, and 3.6% C18:3 on the 8 th day of culture; on the 4 th day, however, the levels of C14:0, C16:1 and C18:3 were higher (13.5%, 1.4% and 4.6%, respectively), showing increased concentration of higher unsaturated acids in this microalgae. Other authors found 11.4% and 38.9% C14:0, 14.5% to 25.2% of C16:0, 16.1% to 19.6% C18:1, 8.6% C18:2, and 15.4% C18:4 [8,42,48], as well as 48.06% SAFA, 39.16% MUFA, and 12.72% PUFA in I. galbana [44], which are different from the levels found in the present study. The amount of 25.4% of C18:1, 15.2% C16:0, 14.6% C18:3, 9.0% C18:4, 6.4% C18:2 were found in T. gracilis [50].…”
