Growth of Haematococcus pluvialis Flotow in alternative media.
Current study investigates the effect of two alternative media NPK (20-5-20) fertilizer and NPK plus macrophyte (M+NPK) compared to the commercial medium (WC) under growth rate and physiological parameters in batch culture mode (2-L), and verifies whether the use of fertilizer (NPK) and macrophyte (Eichhornia crassipes) would be a good tool for Haematococcus pluvialis culture in the laboratory....
متن کاملSources of inorganic fertilizer in the growth of Haematococcus pluvialis Flotow (Chlorophyceae)
The influence of inorganic fertilizer media at different concentrations on the growth and biochemical composition of Haematococcus pluvialis microalgae was evaluated. Microalgae were placed in a bath culture with inorganic fertilizer (NPK) medium and WC medium during 28 days, Growth and biological aspects of microalgae between the media were compared. Mineral concentrations affected the physiol...
متن کاملEffects of some parameters in upscale culture of Haematococcus pluvialis Flotow.
Growth rate and medium parameters between two bench scale volumes (13-L and 250-L) were compared. Experiments were maintained batch mode and culture parameters were periodically measured during a 13-day period. Culture growth during the cultivation of algae Haematococcus pluvialis was determined qualitatively by cell counting, optical density, dry weight, ash content, amount of chlorophyll-a, t...
متن کاملOptimization of biomass, total carotenoids and astaxanthin production in Haematococcus pluvialis Flotow strain Steptoe (Nevada, USA) under laboratory conditions.
The microalga Haematococcus pluvialis Flotow is one of the natural sources of astaxanthin, a pigment widely used in salmon feed. This study was made to discover optimal conditions for biomass and astaxanthin production in H. pluvialis from Steptoe, Nevada (USA), cultured in batch mode. Growth was carried out under autotrophic (with NaNO3, NH4Cl and urea) and mixotrophic conditions (with 4, 8, 1...
متن کاملMedia Screening for Obtaining Haematococcus pluvialis Red Motile Macrozooids Rich in Astaxanthin and Fatty Acids
Astaxanthin from Haematococcus pluvialis is commercially produced in a two-stage process, involving green vegetative (macrozooid) and red aplanospore stages. This approach has been scaled up to an industrial process but constraints limit its commercial success and profitability, including: contamination issues, high pigment extraction costs, requirements for high light levels and photo-bleachin...
