Abstract

The present invention is process of fermenting Crypthecodinium cohnii(Seligo)Javornicky as one kind of marine micro algae to produce docosahexaenoic acid grease. The process includes continuous culturing Crypthecodinium cohnii(Seligo)Javornicky in liquid culture medium to obtain algae cell and extracting the algae cell to obtain docosahexaenoic acid grease. The present invention has proper marine micro algae strain, vitamins added into the culture medium and proper technological process, so that the present invention has high yield of docosahexaenoic acid grease, docosahexaenoic acid content in algae cell of 30-50 %, algae cell concentration of 20-40 g / L and oil content in algae cell of 20-50 %.

Description

Technical field

[0001] The invention relates to a method for producing polyunsaturated fatty acid docosahexaenoic acid (DHA) oil, specifically a method for fermentation with Crypthecodinium cohnii (Selgo) Javornicky in marine microalgae Method for producing docosahexaenoic acid grease. Background technique

[0002] In recent years, the important role of polyunsaturated fatty acids (PUFAs) on human health has received increasing attention. Among them, docosahexaenoic acid is favored by people because of its important physiological functions in humans and animals. Studies have shown that DHA is a basic component of cell membranes in certain tissues of the human body; it plays an important role in the development of the visual system and nervous system of infants and young children; it also has cholesterol-lowering effects, anti-coagulation effects and cancer-inhibiting effects, preventing Alzheimer's disease It is a kind of fatty acid necessary for the growth of juvenile fish.
