摘要：

Cane molasses is beneficial for lipid and camtenoid production in microalgae. We made a survey for the lipid and carotenoid production profile of R. toruloides M18 (MT) with various concentrations of molasses under nitrogen-deficited conditions. The production of alpha-linolenate and torularhodin from MT were 1.22- and 14.68-fold higher than those of the wild-type strain. We observed that molasses at concentrations of 35 g/L and 70 g/L represented a cheap and environmentally friendly strategy for producing lipids and carotenoids. Transcriptome and WGCNA analysis demonstrated that the genes relevant to the lipid and carotenoid production, including MYB, bHLH, Delta-4 desaturase, Delta-12 desaturase and FA2H, were significantly highly expressed. The results indicated that molasses could represent an inexpensive means for achieving high lipids and camtenoids production in R. toruloides.
