  1. ND: Not detected. Table values correspond to the average result from three independent cultures ± standard deviations. Percentage relative to total carotenoids is indicated in parenthesis. Monocyclic carotenoids include: γ-carotene, keto-γ-carotene, hydroxy-keto-γ-carotene, torulene and hydroxy-keto-torulene.
