摘要

Haematococcus Pluvialis (H. pluvialis) is a microalga of freshwater which is a rich source of carotenoid. The astax-anthin, a type of carotenoid and antioxidant, has many health benefits. It has roles in healthier skin, endurance, heart health, joint pain relief and even can act as a super-antioxidant in cancer treatment. Optimizing physiological parameters of H. pluvialis can be a suitable method for increasing metabolites and producing astaxanthin. In order to improving the growth, pigments, proteins and carbohydrates in H. pluvialis, we used the influence of different concentration of ethanolamine by two methods of treatment and pre-treatment on its green and red phases. In the green phase, the ethanolamine treatment and pre-treatment increased all measured parameters on cells. The ethanolamine treatment also improved the amount of carotenoids and carbohydrates in red cells, but the amount of proteins and dry weight decreased in green cells. The ethanolamine pre-treatment did not have significant effects on dry weight of red cells, while increased the amounts of carotenoids, carbohydrates, and proteins. Moreover, it has effects on xanthophyll and increased the amount of astaxanthin. These results showed that ethanolamine has a high ability for improving signaling pathways of metabolites in H. pluvialis.
