The non‐saponifiable neutral lipid composition of nineteen bacterial strains isolated from Antarctic sea ice were analysed. Nine of these strains produced a novel highly unsaturated straight chain hydrocarbon as the major non‐saponifiable neutral lipid component. The compound was identified as hentriacontanonene (n‐C 31.9 ) by mass spectrometry and the formation of n‐C 31:0 following hydrogenation. The occurrence of n‐C 31:9 also correlated with the production of polyunsaturated fatty acids (PUFA) by the bacterial strains. n‐C 31:9 may therefore represent a novel biomarker for the location of PUFA‐producing bacteria from environmental samples.
