Process for producing biofertilizers/biostimulants from microalgae of the species scenedesmus sp. with intensive co2 capture, biofertilizers/biostimulants obtained by said process and their uses in agriculture

Abstract

The present invention relates to a process for producing biofertilizers/biostimulants from microalgae with intensive CO2 capture, which comprises the following steps: a) preparing an inoculum; b) cultivating for the production of microalgae biomass in a window photobioreactor; c) collecting the biomass by flocculation; d) drying the biomass, and grinding and extracting a polar fraction by solvent in a two-phase system; and e) analyzing the polar fraction by liquid chromatography. The invention also relates to the extracts of wet biomass of the microalgae Scenedesmus sp., obtaining the polar fraction. This polar fraction contains amino acids, sugars, betaine derivatives, vitamin B3 (nicotinamide or nicotinic acid) and pantothenic acid (vitamin B5), the monoterpene loliolide and the tryptophan derivative indole-lactic acid (analogous to indole-acetic acid, a phytohormone of the auxin class). The polar fraction can also be used as an input in the cultivation of soybeans, corn, sugar cane, cotton and coffee, among other cultivated species.
