Cover Story: Haematococcus pluvialis accumulates astaxanthin, which is a high-value antioxidant, during the red cyst stage of its lifecycle. Development of a rigid cell wall in the cysts hinders the recovery of astaxanthin. This article investigates morphological changes and cell disruption of mature Haematococcus pluvialis cysts while using high-pressure homogenization for astaxanthin extraction. Mechanical treatment resulted in 91% of cell disruption and a proportional increase in astaxanthin recovery. This study recommends a synergistic combination of rapid instrumental particle-volume-distribution analysis and microscope-based morphologic phenotyping for the development of practical biorefinery processes that co-produce various biological products, including lipids, proteins, carbohydrates, and astaxanthin.
