Development of Haematococcus pluvialis

Jan 10, 2020

Recently, at the International Academic Forum on Application and Innovation of Haematococcus pluvialis, sponsored by Asia Pacific Algae Application Society (APSAP) and Nanchang University, and exclusively hosted by Green A, guests shared the latest scientific research results of Haematococcus pluvialis industry.

Haematococcus pluvialis is currently found in the scientific community. Following spirulina and chlorella, it is algae food rich in nutritional value and medicinal value. "Haematococcus pluvialis is one of the organisms with the highest natural astaxanthin content and is the main source of natural astaxanthin. Natural astaxanthin is known as a 'super oxidant' and has a wide range of application values. It can not only be used as aquaculture feed additives and human food additives, but also has great application potential in the fields of medicine, cosmetics and nutritional health products.

Yuan Wenqiao, a professor at North Carolina State University, said at the forum. He believes that the astaxanthin extracted by Haematococcus pluvialis is not only because of its high astaxanthin content and activity, the most important thing is that currently only astaxanthin extracted from Haematococcus pluvialis is pure and natural .

astaxanthin

A large number of studies have shown that the accumulation rate and total production of astaxanthin in Haematococcus pluvialis are higher than other green algae, and the ratio of astaxanthin and its esters in Haematococcus pluvialis is very similar to that of aquaculture animals.

"Good algae strains are a prerequisite for the commercial production of Haematococcus pluvialis." Professor Michael A. Borowitzka, a professor and director of the Algae R & D Centre at the University of Perth, Murdoch, Australia, and the founding chairman of the Asia-Pacific Applied Botany Society. According to Hu Zhixiang, a company has cooperated with the Wuhan Botanical Garden of the Chinese Academy of Sciences since 2006 to collect and isolate 38 Haematococcus species from China's domestic terrestrial waters. After single cell cloning, a single algae culture was obtained, and a corresponding algae species bank was established The preservation of algae species provides algae species resources with independent intellectual property rights for the development of natural astaxanthin for the cultivation of haematococcus. The technical team conducted further comparative research on 4 strains of algae suitable for the natural water quality of Chenghai Lake. Through different temperature gradients and breeding, the temperature adaptability and growth of each strain were compared. Indicators. After several experimental studies, WZ1 and WZ2 two strains of Haematococcus are suitable for large-scale breeding in Chenghai Lake area. The astaxanthin content in the test conditions reached more than 3.0% of dry weight. Large-scale farming, the average content of astaxanthin reached 2.23% of the dry weight.
