Deesterification of astaxanthin and intermediate esters from Haematococcus pluvialis subjected to stress

In this study we evaluated the effect of enzymolysis and saponification deesterification processes of astaxanthin and its carotenoid precursors under high irradiance and nitrogen deprivation stress time conditions. Results showed that cholesterol esterase facilitated astaxanthin deesterification (975.65 µg mg-1 DW) while saponification positively affected zeaxanthin (1,038.68 µg mg-1 DW).
