阐述了大量培养盐生杜氏藻的有关条件：在培养过程中需要间断地通ＣＯ２１０ｍｌ／ｓ；加入３０μｍｏ１／ＬＥＤＴＡ、５０μｍｏ１／Ｌｆｅ￣（３＋）、０．１ｍｍｏ１／ＬＭｇ３＋均可提高藻体的生长，对β－胡萝卜素的积累有利；在培养过程中需加０．３ｍｍｏ１／Ｌ的脲素作为氮源，也有利于藻体的生长。
The conditions for culturing Dunaliella salina in large scale are described. CO210ml / s is required to be intermittently fed during the culture process. The addition of 30μmo1 / LEDTA, 50μmo1 / Lfe¯ (3 +) and 0.1mmo1 / LMg3 + The accumulation of β-carotene beneficial; in the culture process need to add 0.3mmo1 / L of urea as a nitrogen source, but also conducive to the growth of algae.
