Marine Ecological Journal| Summary: | The features of ketocarotenoid accumulation in cells of green microalgae Scotiellopsis rubescens Vinatz depending on the medium composition during secondary carotenogenesis stage at cultivation, using a two-stage batch culture, have been revealed. Тhe presence of small amounts of nitrogen and phosphorus in the medium (4 – 5 mg·l-1) reduced the loss of cell number after stress-impact, initiating the secondary carotenogenesis by 1 – 2 orders of magnitude, accelerated the accumulation of total carotenoids by 3 – 4 fold, enhanced its content in cells and culture by 2 fold and more, and also increased the percentage of astaxanthin and its predecessors (adonixanthin and canthaxanthin) in total carotenoids pool. |
