Optimization of cell wall breaking process of the microalgae
Haematococcus pluvialis can synthesize and accumulate astaxanthin, and is regarded as the organism with the highest content of astaxanthin in the current nature. However, only when Haematococcus pluvialis cell wall is broken can the astaxanthin be effectively extracted. Therefore, the breaking of the hard cell wall of Haematococcus …
