Camelina sativa meal hydrolysate as sustainable biomass for the production of carotenoids by Rhodosporidium toruloides

BACKGROUND: meal use as animal feed, there is an increasing interest in further valorizing its macromolecular content or its nutritional value. RESULTS: meal hydrolysate produced 5 ± 0.7, 16 ± 1.9, and 13 ± 2.6 mg/L of carotenoids, respectively. Importantly, the presence of water-insoluble solids, which normally inhibit microbial growth, correlated with a higher titer of carotenoids, suggesting that the latter could act as scavengers. CONCLUSIONS: meal to generate high value-added products.
