Obtaining a protein extract through enzymatic hydrolysis from tobacco leaves and its application as a fertilizer. (Machine-translation by Google Translate, not legally binding)

The object of the invention is to obtain a product from tobacco leaves (fresh and/or dried) discarded for the manufacture of the tobacco itself that act as in the agronomic field as biofertilizer/biostimulant. The selected biochemical process is by enzymatic hydrolysis using proteases. Through this methodology protein extracts are obtained, basically constituted by peptides of low molecular weight and free amino acids of high solubility. Its high N-organic content means that this product is considered optimal for agriculture, as can be seen in the experiments carried out in the tomato crop.

El proceso bioquímico seleccionado es mediante hidrólisis enzimática utilizando proteasas. Mediante esta metodología se obtienen extractos proteicos constituidos básicamente por péptidos de bajo peso molecular y aminoácidos libres de una alta solubilidad. Su alto contenido en N-orgánico hace que dicho producto sea considerado óptimo para la agricultura, tal y como se comprueba en las experiencias realizadas en el cultivo de tomate.
