More Information
Summary:A method for obtaining biofertilizer concentrates and biostimulants for agricultural use from biomass of microalgae, including cyanobacteria, wherein, firstly, the cellular content of the microalgae, including cyanobacteria, is released by rupturing the cells thereof; next, the protein fraction and the cell wall of the microalgae, including cyanobacteria, obtained from said release of the cellular content, are hydrolyzed with proteolytic enzymes until producing free amino acids; next, nitrogen (N), phosphorus (P) and/or potassium (K) excipients are added to the previously obtained product of enzymatic hydrolysis.
