  1. R. glacialis DBVPG 4785 was cultured at different temperatures in GMY medium containing 40 g L-1 glucose. FA within the lipid extract were transformed into the corresponding methyl-esters and were analyzed as described in Methods section. The relative abundance of each FA, the sum of 16- and 18-carbons FA, the sum of the saturated, mono-unsaturated, and poly-unsaturated ones (SFA, MUFA, and PUFA, respectively), and the unsaturation index (UI) are reported as a function of the growth temperature. The values are means of three independent experiments. Within a column, superscripts indicate statistically similar means, P > 0.05, n = 3.
