Abstract
|
|
|
|
To improve biomass and astaxanthin production by wild-type Xanthophyllomyces dendrorhous simultaneously in shake flask culture, physical factors, nutritional factors and carotenogenesis stimulating factors affecting astaxanthin production were studied on base of HPLC quantitative analysis. The results suggested that carotenogenesis precursor composition acetic acid, mevalonic acid, tomato extract, and carrot extract could increase the productivity of astaxanthin markedly based on the optimized temperature, initial pH value, carbon and nitrogen sources conditions.
