Problems solved by technology

There are inevitably some problems in this process technology, such as: in order to meet the requirement of low acid value in alkali refining, excessive alkali is usually added, and some triglycerides will inevitably be saponified; high COD wastewater produced by alkali refining will pollute the environment; Alkali refining requires high temperature treatment for a long time, which will easily cause the peroxide value and anisidine value of the product to increase; high deodorization temperature and long time will easily produce trans fatty acids and other disadvantages

Embodiment 1

[0124]The slant-preserved strain of Mortierella alpine was inserted into a 2L shake flask containing 400 mL of medium, and cultured at a temperature of 28° C. at a rotational speed of 150 rpm for 48 hours to complete the activation culture of the strain. According to the inoculation amount of 0.4%, connect the shake flask seed liquid into the first-level seed tank equipped with the sterilized medium, and cultivate it for 30 hours under the conditions of the culture temperature of 28°C, the ventilation volume of 1vvm, and the tank pressure of 0.04MPa, and the first-level is completed. Seed expansion cultivation. According to the inoculation amount of 3%, the seed liquid of the first-level seed tank was connected to the second-level seed tank equipped with the sterilized medium, and cultivated for 24 hours under the conditions of a culture temperature of 28 ° C, an air volume of 1 vvm, and a tank pressure of 0.04 MPa. Complete secondary seed expansion cultivation. According to ...

Description

[0001] The present invention is a divisional application of the parent application with the application number 201710097797.5. The application date of the parent application is February 23, 2017, and the title of the invention is "A method for producing ARA by microbial fermentation". technical field [0002] The invention belongs to the field of fermentation engineering, and relates to a method for producing ARA by microbial fermentation, in particular to a method for producing mixed oil containing arachidonic acid (ARA) by industrialized fermentation of Mortierella alpina strains. Background technique [0003] ARA, also known as arachidonic acid, full name eicosadonic acid (cis-5,8,11,14-arachidonic acid, ARA), is a polyunsaturated fatty acid of the omega-6 series. ARA is an important essential fatty acid for the human body, and it is also a polyunsaturated fatty acid with the highest content and the widest distribution in the human body. ARA plays an important role as a p...
