Relative carotenoid compositions of H. gelipurpurascens (A) and VUG-A141a (B) during incubation for 26 days on parallel R2A plates incubated in the dark at 18°C. Percentages were determined from online PDA detection of absorption at 470 nm relative to a 600-nm reference as quantified using the HPLC auto-integrator. Values are the means of three independent replicates, and error bars (where visible) show 1 standard deviation.
