Phân lập một số dòng vi tảo biển dị dưỡng có khả năng sản xuất carotenoid ở vùng biển Cà Mau

Abstract

Carotenoid is an antioxidant that brings many benefits to human health. This study was conducted to identify heterotrophic microalgae capable of producing high levels of carotenoids. Results showed that five strains of microalgae isolated from leaf samples and water in Ca Mau waters contain carotenoids. After carotenoid extraction with 90% acetone and 90% ethanol, both D5 and D6 have a very high total carotenoid content. In particular, the D5 strains has a carotenoid content corresponding to two types of solvent, respectively 3017 μg / kg dry weight; 7569 μg / kg dry weight. D6 carotenoids were found to be 4769 μg / kg dry weight respectively; 3760 μg / kg dry weight.
