Table 2 Comparison of biomass productivity, carbohydrate productivity, and CO2 fixation rate of S. obliquus CNW-N grown under different weather conditions in outdoor surroundings

From: Feasibility of CO2 mitigation and carbohydrate production by microalga Scenedesmus obliquus CNW-N used for bioethanol fermentation under outdoor conditions: effects of seasonal changes

Weather condition Avg. light intensity (μmol m−2s−1) Avg. water temperature (oC) Biomass productivity (mg L−1d−1) Carbohydrate (glucose) productivity (mg L−1d−1) CO2 fixation rate (mg L−1d−1)a
Rainy (Typhoon) 182.2 29.1 183.8 ± 18.6 80.8 ± 6.9 (64.6 ± 5.3) 321.7 ± 32.6
Sunny 270.8 31.9 245.8 ± 27.9 111.8 ± 13.6 (90.8 ± 9.9) 430.2 ± 48.8
Cold 52.0 20.2 114.9 ± 20.1 45.0 ± 5.9 (33.9 ± 4.9) 201.1 ± 35.2
  1. Values are the mean ± standard deviation of three replicated experiments. (CO2 feeding concentration = 2.5%; working volume = 60 L.)
  2. aCalculated from the following equation: CO2 fixation rate = Biomass productivity (mg L−1d−1) × C(%) × 44/12
