Resource utilization of Haematococcus lacustris

Haematococcus lacustris, as a microalga, is renowned for its ability to accumulate high concentrations of astaxanthin, a natural antioxidant, under adverse environmental conditions. This characteristic endows the algae with broad application prospects in the fields of food, cosmetics, health, and so on. Nevertheless, the growth characteristics and yield of Haematococcus lacustris are influenced by various factors, including light intensity, temperature, nutrient salt concentration, and the genetic traits of the algal strain itself. Consequently, exploring the growth potential, application value and transcriptome differences of different phenotypes of Haematococcus lacustris holds significant importance for optimizing its cultivation conditions, enhancing productivity.
