These researchers also ranked strains according to the estimated lipid productivity of rapidly
growing cells, based on the calculated growth rates and estimated lipid contents of exponential
phase cells. The top strains resulting from this analysis are shown in Table II.A.4. However, the
optimal strategy for maximizing lipid yield in actual mass culture facilities may require an
Ainduction@ step (i.e., manipulation of the culture environment, possibly involving nutrient
deficiency). The ranking of strains would be very different in that case.
