The interactions between and within these two different treatments
of drying and cell disruption were analyzed with two-way
ANOVA at 95% confidence level, and results are presented in
Table 1. Variations in drying methods significantly affected the
lipid yields (P = 0.005). Similarly variability in cell disruption processes
also had significant effects on the lipid yield (P < 0.001).
No significant interaction between these two factors of drying
and cell disruption was observed (P = 0.477). Post-hoc analysis
with Tukey’s test was carried out to perform pairwise comparisons
within each group to investigate their impacts on lipid yields. Different
drying processes were compared to all cell disruption procedures.
Least square means were calculated to be 11.92 for sun
dried samples, 14.19 for oven dried samples, and 15.07 for freeze
dried samples with a standard error of 0.63. These comparisons
