Nutrient recovery from agro-industrial effluents as precipitate minerals for use as fertilizers in agriculture is a promising strategy to reach sustainability. Struvite precipitation (MgNH4PO4.6H2O) is one of the most studied methods for phosphorus (P) recovery from waste waters; its use as a slow-release fertilizer has been often tested. This method also allowed the potassium (K) recovery as K-struvite (MgKPO4 .6H2O). The leachate has been considered as a major threat of composting facilities to the environment - due to
its high biochemical oxygen demand and nutrient content (K, N e P). The leachate from a composting of horse bedding manure and left vegetables from an agro-processing industry showed high content of K (2,256 mg L -1), and low levels of ammoniacal nitrogen (217 mg L-1) and P (83 mg L-1). Adding soluble sources of phosphorus (H 3PO4) and magnesium (MgCl2) followed by pH adjusting (8 to 10), we reached the simultaneous formation of NH 4-struvite and K-struvite, as evidenced by X-ray diffraction. Besides
composting leachate, struvite precipitation might be a feasible route to other agro-industrial waste waters with high K and N.
Este estudo objetivou avaliar a composição de nutrientes do lixiviado da compostagem de esterco de cavalo e sobras de hortaliças de uma agroindústria de processamento mínimo e o potencial para a recuperação de nitrogênio amoniacal (NH 4+) e potássio (K) na forma de estruvita em condições de laboratório. |

Abstract: Bioactive amines were determined in selected passion fruit species and throughout fruit development. The same amines (spermine, spermidine, agmatine, putrescine and tryptamine) were found in four Passiflora species (2008?2010 growing seasons) at different concentrations: P. alata had higher polyamines (spermine + spermidine, 8.41 mg/100 g); P. setacea and P. nitida had higher putrescine (> 7.0 mg/100 g); and P. setacea had higher agmatine contents (1.37 mg/100 g) compared to the others. The indolamine tryptamine was present at low concentrations in all species (~ 0.05 mg/100 g). P. nitida and P. alata had the highest soluble solids (~ 18°Brix); P. edulis had the lowest pH (2.97) and P. nitida the highest pH (4.19). Throughout P. setacea fruit development, the concentrations of spermidine, putrescine and agmatine decreased; spermine contents did not change; and pH decreased. Fruit shelf life and some of the health promoting properties of Passiflora and their synthesis are modulated by species. |
