Statistical analysis
The statistical significance of the cultivation temperature and light
intensity on the algal cell density was assessed using ANOVA F-test.
The experimental data measured under each condition were pooled
together. The significance test was done for each factor using one-way
ANOVA. The null hypothesis is that the population means measured at
different levels of the experimental factor are all equal. The alternative
is that they are not all equal, or the factor is significant. The statistical
significance level cut-off was chosen as P = 0.05.
