New species can accumulate high amounts of three carotenoids

According to news from the Kunming Institute of Botany, Chinese Academy of Sciences, the research team of the Huang Junchao Research Group, a key laboratory for wild plant research and development, has made progress in the study of the synthesis and accumulation of carotenoids in the consumption of chlorella, and discovered a high accumulation of three types of carotenoids. Species. The series of research results has been published in international authoritative journals such as Metabolic Engineering Biotechnology and Journal of Agriculture and Food Science.

Carotenoids are one of the most important natural pigments in nature. β-carotene is the main source of animal vitamin A. Zeaxanthin and lutein are macular pigments of the eye's retina. In the main human diet, the content of these three carotenoids is extremely low, and it is often difficult to meet the needs of a healthy body.

Chlorella is a unicellular edible Chlorella which can grow heterotrophically in the absence of light to obtain up to 51 grams of stem cells per liter. The biomass is several dozen times that of photosynthetic autotrophic algae. Previously, the research team has clarified the pathway and regulation mechanism of the synthesis of carotenoids of Chlorella, and on this basis, the research group screened a strain of mutant algae from 100,000 monoclonal algae through chemical mutagenesis. The mutant algae strain was unable to catalyze the conversion of zeaxanthin to astaxanthin due to the inactivation of the ketoenzyme gene, resulting in up to 7 mg, 13.1 mg and 6.34 mg of zeaxanthin, lutein and β-carotene, respectively, per gram of mutants.

In other words, the carotenoid content of 1 g of this mutant algae strain dried algae powder is more than 1000 times that of corn, which can meet the needs of a single adult carotenoid and other nutrients. This is the only species that has so far been able to accumulate three essential human and animal essential carotenoids at high levels. It can be used as a new generation of functional foods and plays an important role in the health industry.
