BBM (Bold’s basal medium), ST (sodium thiosulphate), Trp (tryptophan), aSFA-saturated fatty acids; bMUFA- monounsaturated fatty acids; cPUFA- polyunsaturated fatty acids; dTL- total lipids; eUSF:SFA- ratio between unsaturated and saturated fatty acids; USF = (MUFA+PUFA);
The rankings, based on Duncan’s Multiple Range Test, are denoted by superscripts in the relevant tables and graphs, with ‘a’ denoting the highest rank.
