Figure 1. Potential microalgal biomass productivity in
different ecoregions of South America. S. obliquus sp. C1S
cultures simulating 20 cm-deep ponds in simulated-climatic conditions in
(A) Comodoro Rivadavia (AR); (B) Buenos Aires (AR); (C) Posadas (AR);
(D) Caracas (VE); (E) Paita (PE); and (F) Fortaleza (BR). S, summer; W,
winter. The heat map was generated with Q-GIS 3.12. Data represent the
mean and range of two independent experiments.
Figure 2. Effect of CO2 supplementation on
biomass productivity of S. obliquus sp. C1S. 20 cm-deep ponds
were simulated in summer or winter, under simulated-climatic conditions
of Buenos Aires, Posadas and Fortaleza. Data represent the mean and
range of two independent experiments.
Figure 3. Effect of CO2 supplementation on
(A-B) carbohydrates or (D-D) lipids accumulation of S. obliquussp. C1S cultures in 20 cm-deep simulated ponds in (A, C) summer or (B,
D) winter climatic conditions of Fortaleza. Data represent the mean and
range of two independent experiments.
Figure 4. Effect of culture depth on algal biomass
productivity. A) S. obliquus sp. C1S cultivated in ePBRs. From
left to right: 20-cm deep culture, OD750 0.3; 20-cm deep
culture, OD750 1.5; 5-cm deep culture,
DO750 1.5. B) Growth curves; C) volumetric biomass
productivity; and (D) areal biomass productivity of S. obliquussp. C1S cultures simulating different pond’s depth in summer (full
circles) or winter (open circles) climate conditions in Fortaleza. Data
represent the mean and standard error of six (winter, 5-cm ponds) or two
(other) independent experiments.
Figure 5. Effect of culture depth on (A-B) carbohydrates or
(C-D) lipids accumulation of S. obliquus sp. C1S cultures
simulating 20-, 10- or 5-cm deep ponds in (A, C) summer or (B, D) winter
climatic conditions of Fortaleza. Data represent the mean and standard
error of four (5-cm deep ponds in winter) or two (other conditions)
independent experiments.
Figure 6. Induction of lipids accumulation by S.
obliquus sp. C1S in simulated 5-cm deep ponds in winter in Fortaleza.
A) Growth curve; (B) lipids content on a dry weight biomass basis; and
time course of (C) biomass; or (D) lipids areal productivity. Data
represent the mean and range of two independent experiments.
