Repeated cultivation: non-cell disruption extraction of astaxanthin for Haematococcus pluvialis.

ABSTRACT: The operation of cell disruption is indispensable but cost much in microalgae industry. To be simplified, two different reaction mechanisms await in the cell to respond to moderated or stressed environment. The physical and chemical changes of enzyme and turgor pressure of cell in this conversion play an important role in the enhancement of biomass and metabolites. Repeated turgor pressure (based on the structure and mechanics of cell wall) and converted enzyme system (based on photosynthesis) were used to loosen cell wall and then repeated cultivation of Haematococcus pluvialis for astaxanthin extraction was proposed. There was no significant difference of extraction yield between the broken cell (94.75 ± 3.13%) and non-broken cell (92.32 ± 3.24%) treated by the repeated cultivation. Mean
