SCHIZOCHYTRIUM AND APPLICATION THEREOF, AND SN-2 DHA-RICH MICROBIAL OIL, PREPARATION METHOD THEREFOR, AND APPLICATION THEREOF

摘要

This disclosure relates to microbial technology, and more particularly to a Schizochytrium strain and a use thereof, a microbial oil containing DHA at an Sn-2 position, and a preparation and uses thereof. Sn-2 fatty acids of a triglyceride in the microbial oil contain 23% or more by weight of DHA. The microbial oil is prepared by fermentation using a Schizochytrium strain, where the Schizochytrium strain is Schizochytrium sp. with an accession number of GDMCC No.60733. The absorption of the DHA in the microbial oil produced by the Schizochytrium GDMCC No.60733 is significantly higher than that in the microbial oil produced by an ordinary Schizochytrium strain, facilitating the enrichment of DHA in human body.
