| Popis: | The cultivation of Scenedesmus armatus was carried out under outdoor Thailand climate conditions. The highest actual growth rate occurred at around 9:00 a.m. to 3:00 p.m., with a wide pH range of 6.4 to 11. The supply of CO2 had slight influence on growth characteristics but did exert some observable effects on nutritional accumulations. Adding CO2 from 2 to 15% by volume in the aeration (0.2 vvm) caused an increase in lipid and protein from 19.8 to 25.6 and 37.8 to 48.2% w/w, respectively, whereas carbohydrate decreased from 42.5 to 26.2% w/w. Scenedesmus armatus cultivated with 2% CO2-enriched air provided the highest the average of the average biomass productivity of 91.25 mg L(-1) d(-1), which corresponded to a CO2 fixation of 165 mg CO2 L(-1) d(-1) with the average lipid, protein, and carbohydrate productivities of 22.24, 38.34, and 30.67 mg L(-1) d(-1). |
