METHOD USING MICRO-ALGAE FOR HIGH-EFFICIENCY PRODUCTION OF ASTAXANTHIN

摘要

The present invention involves a new method using micro-algae for the high-efficiency production of astaxanthin, said method comprising steps including the heterotrophic culture of micro-algae, dilution, light-induced culture, harvesting of algae cells and the extraction of astaxanthin. The method of the present invention takes full advantage of the rapid growth of micro-algae in the heterotrophic culture stage and of the high accumulation of astaxanthin brought about by the light-induced culture of the great quantity of algae cells obtained through said heterotrophic culture to significantly increase the efficiency of production of astaxanthin in micro-algae and thereby achieve low-cost, high-efficiency and large scale production of astaxanthin through micro-algae. The method not only provides an important technical means to address the large-scale industrial production of astaxanthin through micro-algae but also ensures an ample source of raw material for the widespread utilization of astaxanthin.
