Data analysis
Data are given to 2 decimal places and are reported as
means ± SEM of measurements from three separate reactor tanks
containing the same strain of organism. Significant difference
between time points were determined by Fisher’s protected least
significant different t-test with two-tail probabilities of less than 0.05
considered significant. Significant differences between yeast
strains (as compared to S. cerevisiae from sugarcane molasses)
were assessed by a one-way analysis of variance and the
Student’s t-Test.
