Abstract
Microalgae potential for biofuel production, such as biodiesel, bioethanol, or biohydrogen, is well-known in the academic community. However, to reach the technical and financial feasibility of those processes, it is necessary to utilize microalgal biomass in other operations, reinforcing concepts related to biorefineries. One possibility is the use of biomass and its compounds in agriculture, with the possibility of partial substitution of synthetic fertilizers. The goal of the present work was to determine biostimulating activity of the algae Tetradesmus obliqqus cultured in photobioreactors over cucumber cotyledons. Biomass was subjected to two protocols of water extraction, which were used to determine cytokinin-like activity in recently-germinated cotyledons. The results point out that the extracts have biostimulating activity related to the presence of cytokinins, which implies a higher rate of cellular division and mass gain of the cotyledons. Although preliminary, the results are promising, since microalgal biomass use as a source of molecules with biostimulating action does not interfere with the later utilization of biomass for biofuels production. Therefore, it is expected to contribute to the increase in the technical and financial feasibility of the production of biofuels and other biotechnological products from microalgae biomass.
