| titleOfInvention | Method for producing astaxanthin by cultivating Haematococcus pluvialis by discontinuous two-step method |
| abstract | The invention discloses a discontinuous two-step method for cultivating Haematococcus pluvialis to produce astaxanthin. Between indoor cultivation and outdoor induction cultivation, the following steps are added: Step 1. Change the cultivation conditions, and the pluvialis obtained from indoor cultivation Haematococcus motile vegetative cells are transformed into immobile vegetative cells; step 2, collect and concentrate the algae liquid obtained in step 1, add antibiotics and/or preservatives, and refrigerate at low temperature; step 3, remove the algae liquid in the refrigerated algae liquid Antibiotics and/or preservatives are added to the diluted medium, and aerated culture is carried out under weak light conditions to activate the immobilized vegetative cells. The method of the present invention can concentrate and store the vegetative cells cultured indoors when the outdoor induced culture is interrupted, and when the climate is suitable, the stored vegetative cells can be quickly activated and induced outdoors to greatly shorten the overall culture period. Improve equipment utilization and productivity, thereby improving the stability of production. |
