AI Technical Summary
Technical Problem
Existing technologies are insufficient for effectively enriching organic selenium and astaxanthin, especially since enrichment methods for Haematococcus pluvialis have not been fully explored.
Method used
A Haematococcus pluvialis strain RXXHp1 is provided. This strain has a certain tolerance to selenium ion stress. It can be enriched with organic selenium and astaxanthin through multi-trophic cultivation and applied to the preparation of wine to increase the content of active substances.
Benefits of technology
Under selenium ion stress, Haematococcus pluvialis RXXHp1 can synergistically enrich organic selenium and astaxanthin, significantly increase the astaxanthin and lutein content in wine, improve the color and flavor of wine, and enhance antioxidant capacity.

Abstract
This disclosure relates to the field of microbial technology, and provides a Haematococcus pluvialis RXXHp1, which was deposited at the China Center for Type Culture Collection on May 19, 2023, with accession number CCTCC NO: M 2023791. This disclosure also provides an application of the above-mentioned Haematococcus pluvialis RXXHp1, including: using Haematococcus pluvialis RXXHp1 to enrich at least one of organic selenium and astaxanthin under selenium ion stress. This disclosure also provides algal powder comprising the above-mentioned Haematococcus pluvialis RXXHp1, and the application of the above-mentioned Haematococcus pluvialis RXXHp1 or the above-mentioned algal powder in the preparation of wine. The Haematococcus pluvialis RXXHp1 disclosed herein exhibits a certain tolerance to selenium ion stress, not only enriching organic selenium but also promoting the accumulation of astaxanthin. Furthermore, using the aforementioned Haematococcus pluvialis RXXHp1 in winemaking can significantly increase the content of active substances such as astaxanthin and lutein in the wine, thereby improving the color and flavor of the wine and enhancing its antioxidant capacity.
