O grão-de-bico é uma das principais fontes de proteína vegetal do mundo. Essa leguminosa apresenta também propriedades medicinais na prevenção do câncer e diminuição do colesterol. O objetivo do trabalho foi selecionar estirpes de rizóbio para grão-de-bico. Os tratamentos foram 10 estirpes de rizóbio recomendadas para cultura pelo Mircen e uma testemunha com adição de nitrogênio. Os resultados demonstraram que nenhuma das estirpes de rizóbio testadas apresentou fixação biológica de nitrogênio superior a testemunha com nitrogênio mineral. Conclui-se que deve-se continuar os ensaios de seleção a fim de obter estirpes que permitam a eliminação da adubação nitrogenada na cultura de grão-de-bico. |

Abstract: Enabling the use of castor cake in animal feeding is an excellent alternative strategy to reduce feed costs. The cake is a by-product derived from the extraction of the castor oil by the biodiesel industry whose chemical composition is satisfactory despite the presence of antinutritional factors like toxic lectins, which require detoxification before it can be used as a dietary ingredient. The aim of the present study was to evaluate alternative chemical sources in the degradation and inactivation of ricin and Ricinus communis agglutinin (RCA), two lectins from castor cake. Ten chemical compounds were evaluated: sodium hydroxide, monodicalcium phosphate, dicalcium phosphate, calcium oxide, calcium hydroxide, calcitic limestone, magnesian limestone, urea, potassium chloride, and sodium chloride. Gel electrophoresis indicated 100% lectin degradation only in the cakes treated with 90 g sodium hydroxide and 2500 mL water per kg of cake. The hemagglutination assay was crucial to providing innocuousness to the treated cakes, with total absence of hemagglutinating activity observed in the castor cakes treated with 60 or 90 g sodium hydroxide in water volumes equal to or higher than 1500 mL/kg of castor cake and in the cakes treated with 90 g calcium oxide with 2500 or 3000 mL water/kg castor cake. Thus, though depending on the concentration of the chemical compound and on the volume of water per kilogram of treated cake, sodium hydroxide and calcium oxide showed to be promising chemical products for degradation and complete inactivation of the lectins present in castor cake to allow its use as an ingredient in animal diets.
