Effect of the Average Irradiance Related Temperature on Microalgae Cell Growth for Four Countries
Authors: , , ,
Abstract: The growth of Microalgae is significantly influenced by the environmental controlling factors such as light, CO2, nutrients, and temperature. Microalgae cells require light for photosynthesis to ensure cell proliferation in the light, peripheral, and dark zones respectively. In some countries like Bangladesh, China, Sri Lanka, and Maldives, where tropical and subtropical climates prevail, optimizing these factors is crucial for enhancing microalgae growth and biomass yield. The average irradiance provides the energy required for photosynthesis, while temperature modulates the biochemical reactions within the cells.The controlling of temperature is crucial to prevent photo-inhibition and cellular damage. This study is investigated the combined effect of average light irradiance and temperature on microalgae cell growth for a photo-bioreactor at four specific locations. We found that the average irradiance is high in the middle of the day of the month of June, which consecutively increases the culture temperature, which is around 370C beyond the optimal temperature. The optimum temperature range for outdoor cultivation of microalgae is about 220C-320C.The geographic differences further impact productivity, necessitating adaptive cultivation strategies such as photoperiod control and temperature regulation.
