The robust cell wall structure of Haematococcus pluvialis ( H. pluvialis ) consists of polysaccharides and tough non-hydrolysable sporopollenins, which makes it difficult to extract superpotent antioxidant, astaxanthin from these cells. Therefore, breakdown of cell wall is a key step in the overall process of astaxanthin recovery. In this study, the mechanism of three well-established chemical techniques for cell disruption of H. pluvialis cysts [ionic liquids (IL), hydrochloric acid (HCl) and multiple enzymes (multi-enzyme, ME)] on deconstruct...
