Fig. 2: Effect of glucose on growth of P. croceum and corticrocin production after 9 weeks of cultivation on MMN1/10 with different available glucose concentrations (0.15, 0.6, 2.5, 10.0 g l−1).
a, b Give the diameter of the total and yellow (mean ± SE), respectively. Different letters indicated significant differences of the diameter of the total and yellow colony among different available glucose concentrations according to Kruskal–Wallis test with post hoc Mann–Whitney pairwise test at p < 0.05 (n = 5–7). c Gives the ratio between optical density of corticrocin extracts (OD379) and colony dry weight. Different letters indicated significant differences of the ratio between OD379 and colony dry weight among different available glucose concentrations according to Kruskal–Wallis test with post hoc Mann–Whitney pairwise test at p < 0.05 (n = 4). The test statistic H and p values from Kruskal–Wallis test are shown in the upper left-hand corner of each figure.
