Abstract Background The increasing emission of flue gas from industrial plants contributes to environmental pollution, global warming, and climate change. Microalgae have been considered excellent biological materials for flue gas removal, particularly CO2 mitigation. However, tolerance to high temperatures is also critical for outdoor microalgal mass cultivation. Therefore, flue gas- and thermo-tolerant mutants of Chlorella vulgaris ESP-31 were generated and characterized for their ability to grow under various conditions. Results In this study, we obtained two CO2- and thermo-tolerant mutants of Chlorella vulgaris ESP-31, namely, 283 and 359, with enhanced CO2 tolerance and thermo-tolerance by using N-methyl-N-nitro-N-nitrosoguanidine (NTG) mutagenesis followed by screening at high temperature and under high CO2 conditions with the w-zipper pouch selection method. The two mutants exhibited higher photosynthetic activity and biomass productivity than that of the ESP-31 wild type. More importantly, the mutants were able to grow at high temperature (40 °C) and a high concentration of simulated flue gas (25% CO2, 80–90 ppm SO2, 90–100 ppm NO) and showed higher carbohydrate and lipid contents than did the ESP-31 wild type. Conclusions The two thermo- and flue gas-tolerant mutants of Chlorella vulgaris ESP-31 were useful for CO2 mitigation from flue gas under heated conditions and for the production of carbohydrates and biodiesel directly using CO2 from flue gas.

El presente estudio evaluó el uso de las microalgas Arthrospira sp., Chlorella sp., Isochrysis sp. y Nannochloropsis sp. como constituyentes parciales del alimento balanceado para tilapia del Nilo (Oreochromis niloticus) bajo condiciones de cultivo estático en un estudio de 53 días de duración. Un alimento balanceado comercial con contenido de proteína cruda de 45% se utilizó como dieta control, mismo que se molió finamente y se reconstituyó incorporando, a un nivel de inclusión de 25% de la dieta, las harinas de las cuatro especies de microalgas mencionadas. Se analizaron parámetros de producción de tilapia, incluyendo índices de crecimiento y supervivencia, mediante análisis de varianza. Los índices de crecimiento, tales como peso final, peso ganado y porcentaje de peso ganado de los peces alimentados con las microalgas Arthrospira sp. y Chlorella sp., así como la supervivencia, fueron similares a los de aquellos que recibieron la dieta control, mientras que el crecimiento de peces alimentados con las microalgas Isochrysis sp. y Nannochloropsis sp. fue inferior estadísticamente. Estos resultados indican que Arthrospira sp. y Chlorella sp. pueden ser incorporadas a un nivel de 25% del alimento balanceado sin afectar significativamente el crecimiento o la supervivencia de O. niloticus.ABSTRACTIn the present study, the use of the microalgae Arthrospira sp., Chlorella sp., Isochrysis sp., and Nannochloropsis sp., as partial constituents in diets for Nile tilapia (Oreochromis niloticus), was evaluated in static tanks in a 53-day study, with a commercial diet containing 45% crude protein as a control treatment. Then, we replaced 25% of this diet with meals derived from each of the four microalgae species. Analysis of variance was employed to evaluate fish growth performance. Fish fed the diets with the microalgae Arthrospira sp. and Chlorella sp. had growth performance comparable to that of fish fed the control diet, as evaluated by growth parameters, such as final weight, weight gain, and percent weight gain, among others. In contrast, growth of fish receiving the microalgae Isochrysis sp. and Nannochloropsis sp. was significantly lower. Results of the present study indicate that the use of 25% of Arthrospira sp. and Chlorella sp. meals incorporated into the diet of O. niloticus does not compromise fish development, although there seems to be an opportunity for a further increment of the replacement level.
