dc.description.abstract | 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 secreted during the fermentation; FHE,
fermentation broth without bacteria and FH, the FHE hydrolysate in which enzymes
were denatured. Enzymatic hydrolysates showed a different chemical composition
compared with fermented hydrolysates and OK. It had a higher protein concentration as
well as C, P and K. The proteins of OK were converted into peptides with a lower
molecular weight, the fermented hydrolysates being those with the lowest molecular
weight profile. The influences of hydrolysates and OK were tested in soil, finding that
β-glucosidase, phosphatase and dehydrogenase activities were stimulated by every
treatment. However, it was observed that EH produced a greater stimulation of
dehydrogenase and phosphatase than both OK and fermented BS. The bacterial and
fungal phospholipid fatty acids were also higher in soils amended with BS than those of
the control and soils with OK. It has also been found that β-glucosidase, phosphatase
and microbial biomass were dose-dependent in every treatment, but dehydrogenase only
was dose-dependent in EH and OK treatments. | es |
