This paper presents both, the design and the development of a monitoring and control system via web for a closed microalgae crop and the results that were gotten using the strain Haematococcus pluvialis. The research was done at Sabana University (Colombia) and it aims to quantify the kinetic growth associated to the increment of biomass and the development of red pigment inside the cells when exposed to different wavelength (λ), constant temperatures, agitation and cycles of light/darkness over the crop. It was found that for short wavelengths (470nm -blue light) the cell size, the quantity of red pigment and the growth kinetics were higher, meanwhile growth was at a lower rate in the crop illuminated with green light (525nm). All of the above was established thanks to a system that allowed real time control and monitoring without human interference. This increases the reliability of the bioprocess data and gains more efficiency in this kind of researching.
