    摘要： Disclosed is a fermentation method of astaxanthin using Phaffia rhodozyma comprising the steps of: (a) in the growing phase, feeding of a nutrient medium containing glucose or sucrose based on the specific growth rate (µ) of Phaffia rhodozyma cells, and (b) in the astaxanthin production phase, feeding of the nutrient medium based on the astaxanthin production rate, while keeping the glucose concentration in the fermentation broth almost 0 g/L during the whole fermentation period.

    摘要： The present invention relates to a gene useful in a process to increase the microbial production of carotenoids. The carotenoids astaxanthin is distributed in a wide variety of organisms such as animals, algae and microorganisms. It has a strong antioxidation property against reactive oxygen species. Astaxanthin is used as a coloring reagent, especially in the industry of farmed fish, such as salmon, because astaxanthin imparts distinctive orange-red coloration to the animals and contributes to consumer appeal in the marketplace.
