| Abstract: | Abstract The bacterial fatty acids of three strains of Desulfobulbus grown on propionate were analysed. The fatty acid profiles of all three strains were very similar, being dominated by C17: 1Δ11, which represented approx. 50% of the total fatty acids, and with major contributions from C15:0, C16:0, C15:1, C18:1Δ11 and C14:0. This data indicates that all three strains are closely related despite their different habitats (1 marine and 2 freshwater) and that C17:1Δ11 is a biomarker for Desulfobulbus . |
