Effect of salt stress on fatty acid alterations in some strains of Dipodascopsis and Dipodascus spp

The effect of salt stress (8% w/v NaCl) on fatty acid composition of eight strains of Dipodascus and Dipodascopsis spp. varied from being of slight influence only (Dipodascopsis uninucleata), to decreasing the content of 18:2 (D. reesii, D. tetrasperma and D. australiensis) and to decreasing both 18:1 and 18:2 (D. tothii and D. aggregatus) with a concomitant rise of 14:1 and 16:1. With the exception of D. aggregatus, NaCl inhibited lipid accumulation in all strains. Only trace amounts of fatty acids over C18 in chain length were found.
