The effect of different sesquiterpenes on carotenoid synthesis in
Phaffia rhodozyma was studied. Addition of squalene to the culture medium resulted in a decrease in the echinenone and
trans-astaxanthin concentrations, whereas
-carotene remained unchanged. The role of squalene as an inhibitor of ketocarotenoid synthesis in
Ph. rhodozyma is discussed.
