FEATURES OF SECONDARY CAROTENOGENESIS IN VEGETATIVE CELLS OF HAEMATOCOCCUS PLUVIALIS FLOTOW (CHLOROPHYСEAE) UNDER DIFFERENT CONDITIONS OF MINERAL SUPPLY
Keywords:
Haematococcus pluvialis, cultivation, astaxanthin, nitrogen, phosphorusAbstract
Influence of nitrogen and phosphorus concentrations in nutrient medium on growth rate and astaxanthin accumulation in vegetative cells of green microalga Haematococcus pluvialis under condition of single-stage semi-continuous culture has been investigated. It has been shown that the maintenance of minimum level of biogenic elements in a medium within the limits of 0.2 – 0.4 mM N and 0.01 – 0.02 mM P is necessary for keeping of monad cell structure, long-term cell division and astaxanthin accumulation.
