Estudo do enriquecimento protéico da algaroba (Prosopis juliflora) utilizando Lentinus crinitus CCIBt 2611 visando a produção de ração animal.

Abstract

Our purpose was study of protein enrichment of algaroba (Prosopis juliflora) by Lentinus crinitus CCIBt 2611 aiming to produce animal feed. The effects of temperature (28, 34, and 40 °C), soybean flour supplementation (0, 5, and 10 %), and fermentation time (0, 7, and 14 days) on protein enrichment was evaluated by a 2³ central composite design in duplicate with four central points, considering significant p < 0,05. The fermentation was carried out in closed pots containing 30 g of substrate with or without soybean flour, 75 ml of distilled water, and inoculum. The temperature and fermentation time did not show effect and the best condition for protein enrichment was using 10 % of soybean flour. The model obtained, P = 7,44 − 0,54X1+ 3,17X3 − 0,73X3 − 0,79X23 ± 0,81,, was significant and predictive, with R2 = 0.9290 and pure error = 0.8106.
