Salinity-driven canthaxanthin enhancement in Chlorosarcinopsis PY02: a practical spot test for microalgal bioprocess optimization

These findings highlight <i>Chlorosarcinopsis</i> PY02 as a promising candidate for sustainable, large-scale production of ketocarotenoids. The study also demonstrates a cost-effective and scalable approach for inducing carotenoid biosynthesis in <i>Chlorosarcinopsis</i> PY02, with strong relevance for sustainable pigment production. The simple visual screening method provides a practical tool for preliminary strain and condition optimization in microalgal bioprocess development.
