Use of cheap raw materials produced by fermentation of astaxanthin
Abstract: Astaxanthin is a carotenoid keto form can be used as antioxidants, pigments and food additives, medicine, food, aquaculture has a very wide range of applications. This article outlines the structure of astaxanthin, nature, origin, function, application, development prospects. The experimental production of red yeast Phaffia astaxanthin, it is natural astaxanthin can be produced one of the main microorganisms studied by yeast fermentation of Phaffia astaxanthin production by the method and the production conditions of this experiment The main purposes. Research method is to first find the single factor test medium, the best nitrogen source is urea, the best carbon source is sucrose, the best inoculum is 6%. On this basis, orthogonal experimental design method on the fermentation medium components were initially optimized for the industrial production of astaxanthin to further provide a reference. Keywords: Phaffia rhodozyma; astaxanthin; cheap raw materials; fermentation
