✦ Synopsis
A number of cyanobacteria showing a high degree of adaptation to life under reduced oxygen tensions as witnessed by their potency of facultative anoxygenic CO2 photoassimilation with sulfide as electron donor were found to lack polyunsaturated fatty acids in their lipids. Lack of polyunsaturated fatty acids was found in representatives of different taxonomic groups. One of the strains lacking polyenoic acids was Oscillatoria limnetica, which can alternatively grow aerobically or anaerobically with sulfide as electron donor. This organism was found to synthesize monounsaturated fatty acids by desaturation of their saturated counterparts, in the presence as well as in the absence of molecular oxygen.
