摘要: In the present study, effects of four different culture media on growth, astaxanthin production and morphology Haematococcus pluvialis LUGU were studied under two-step cultivation. The interactions between synthesis secondary messengers, reactive oxygen species (ROS) mitogen-activated protein kinases (MAPK) also investigated. first green vegetative cell stage, maximal biomass productivity (86.54 mg L−1 day−1) was obtained in BBM medium. induction highest content (21.5 mg g−1) occurred BG-11 medium, which higher than any other media. expressions MAPK biosynthetic genes media, whereas ROS lower. Biochemical physiological analyses suggested that ROS, gene expression involved biosynthesis H. conditions. This study proposes a cultivation strategy to efficiently produce using microalgae.
