Cellular Fatty Acid Composition of Deleya halophila: Effect of Growth Temperature and Salt Concentration Monteoliva-Sanchez, Mercedes and Ferrer, M. Rita and Ramos-Cormenzana, Alberto and Quesada, Emilia and Monteoliva, Miguel,, 134, 199-203 (1988), doi = https://doi.org/10.1099/00221287-134-1-199, publicationName = Microbiology Society, issn = 1350-0872, abstract= The cellular fatty acid composition of Deleya halophila, a moderately halophilic bacterium, grown at different temperatures and NaCl concentrations is reported. When the temperature was lowered the amounts of monounsaturated C16:1 and C18:1 fatty acids increased with a corresponding decrease in the amounts of saturated C16:0 and C18:0 fatty acids. Increasing the salt concentration in the medium resulted in an increase of cyclopropane fatty acids, with a concomitant decrease in the monounsaturated fatty acids, suggesting that cyclopropane synthetase is activated or induced by high levels of salt., language=, type=
