Resumen de: WO2024205443A1
The invention relates to the field of microbiology. The present method envisages loading a microalgal culture into a photobioreactor for cultivation and measuring the variable fluorescence (φ''). On the basis of the measuring results, a culture medium is prepared in the photobioreactor, and a base level for light intensity is set. Readings from a fluorescence sensor and a biomass sensor are measured. The fluorescence sensor and biomass sensor readings are measured throughout the cultivation process. On the basis of the measuring results, cultivation is continued if φ'' does not fall below a predetermined value and the biomass increases. If this condition is not met, the photobioreactor is cleaned and cultivation is restarted. During cultivation, the light intensity level is adjusted and/or shading devices are controlled according to the results of a comparison of the current value of φ'' and an optimal value φ''opt. for the culture in the photobioreactor. The culture is harvested when it is found that a nutrient mixture has been exhausted, or when a predetermined culture concentration has been reached, or when it is found that the culture has ceased to grow. The invention is directed toward increasing the growth rate of microalgae by tracking the state of the photosynthetic apparatus thereof, and also toward reducing energy expenditure on lighting.
