PRODUCTION METHOD AND DEVICE FOR PREVENTING AND TREATING CONTAMINATION OF PARAPHYSODERMA SEDEBOKERENSIS IN HAEMATOCOCCUS PLUVIALIS

摘要

Provided is a method of preventing and controlling contamination in a scale culture of haematococcus pluvialis, comprising: 1) placing haematococcus pluvialis ina primary photo-bioreactor and cultured haematococcus pluvialis swarm cells; 2) transfering haematococcus pluvialis swarm cells to a secondary photo-bioreactor and adding a stress medium; 3) after more than 10% of the haematococcus pluvialis swarm cells in the secondary photo-bioreactor have changed to fixed cells, controlling and fixing the culturing temperature at 10-22°C so that haematococcus pluvialis spore cell algae fluid enters the astaxanthin accumulation period; and 4) after culturing for 7 - 12 days, obtaining haematococcus pluvialis spores with an infection rate of less than 1% of Paraphysoderma sedebokerensis. Also provided is a device for preventing and controlling contamination in a scale culture of haematococcus pluvialis. The device uses the waste heat of flue gases of a factory to provide energy for lowering the temperature of the haematococcus pluvialis algae fluid. The device can save on fuel costs, and reduce emissions of waste gases and harmful gases, thus protecting the environment.
