The predominant fatty acids identified above account for 84.5% o f the total FFA
species. Table 13 shows that the concentrations o f saturated fatty acids (SFAs) was higher in the exponential phase than in the stationary phase when the mixed species
culture was grown on UDA+PDB and UDA alone. Monounsaturated fatty acids
(MUFAs) and polyunsaturated fatty acids (PUFAs) were lower in the exponential phase
than in the stationary phase. When cells were grown on UDA+PDB, the concentration of
the SFAs (295 mg/150 ml) > MUFA (86 mg/150 ml) > PUFA (73 mg/ 150 ml) during
exponential phase (Table 13).
