The invention discloses a method for obtaining concentrates of fertilizers and stimulants from biomass of microalgae, 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 the release of the cellular content, are hydrolyzedwith 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. 本发明公开一种从微藻的生物质获得肥料和刺激剂的浓缩物的方法，其中，首先，通过使所述包括蓝细菌在内的微藻的细胞破裂释放所述微藻的细胞内容物；然后，用蛋白水解酶水解从所述细胞内容物的所述释放中获得的所述包括蓝细菌在内的微藻的蛋白质部分和细胞壁，直到产生游离氨基酸；然后，将氮(N)、磷(P)和/或钾(K)赋形剂添加到先前获得的酶水解产物中。
