Advances in Genetic Engineering Breeding of Astaxanthin-producing Yeast
Astaxanthin is a ketocarotenoid with significant biological activity and high economic value.It is mainly used in pharmaceuticals,health care products,cosmetics,and food and feed industries.At present,the low yield of natural microbial astaxanthin restricts its expansion of application.Therefore,the method of producing astaxanthin through genetic engineering of microorganisms has attracted extensive attention.This paper reviews the research progress of improving the yield of original or heterologous astaxanthin in yeast by genetic engineering breeding in recent years.
