Abstract excerpt

Phaffia rhodozyma strain Ant-1 produces more carotenoids, known as antioxidants, but it was more sensitive to light plus toluidine blue O (TBO), a superoxide producer, than wild strain 67-385 at 20 degrees C. Carotenoid hyperproducing mutants (CHMs), Ant-1 and 2A2N, exhibited decreased activity o...
