Isolation and identification of carotenoid-producing Rhodotorula sp. from Pinaceae forest ecosystems and optimization of in vitro carotenoid production

Yeasts are alternative source of natural carotenoids, a group of colored terpenoids with various market applications. Carotenoid Production by yeast fermentation technology is greatly effective and proposes considerable benefits with large scale production, cost effectiveness and safety. In this stu...
