Production of biostimulants from okara through enzymatic hydrolisis and fermentation with Bacillus licheniformis. Comparative effect on soil biological properties.

In this work okara (OK), a by-product of soy milk manufacturing, is submitted to an enzymatic hydrolysis and a fermentative process to produce different soil biostimulants (BS): EH, hydrolysate obtained by the enzymatic process; FHEB, fermentation broth with Bacillus licheniformis and the enzymes se...
