Title:
MORTIERELLA ALPINA AND USE THEREOF, AND MICROBIAL OIL RICH IN ARA AT POSITION SN-2, PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/104164
Kind Code:
A1
Abstract:
Disclosed are Mortierella alpina and the use thereof, and a microbial oil rich in ARA at position Sn-2, a preparation method therefor and the use thereof, which belong to the field of microbial technology. The proportion of ARA at position Sn-2 of the triglyceride in the microbial oil is not less than 23% by weight. The method for preparing the microbial oil comprises: inoculating a Mortierella alpina strain into a fermentation medium and fermenting same to obtain the product. The Mortierella alpina strain is Mortierella alpina, with a deposit number of GDMCC No.60734. The proportion of ARA at position Sn-2 of the triglyceride in the microbial oil is not less than 23%, so that the absorption rate of the ARA in the microbial oil in the human body is significantly higher than that of the microbial oil produced by conventional strains, promoting the absorption and utilization of the functional fatty acid ARA by the human body.
