^aRatio of saturated to unsaturated fatty acids.

Very early (VE) growth phase is that in which the incubation time is between 20–30 h. Early (E) growth phase is that in which the incubation time is between 50 and 70 h. Late growth phase is that in which incubation time is c. 150 h. Culture conditions as in Table 1.
