| Yeasts were applied to corn grains, containing 16 or 20% moisture, at concentrations of 1 and 2%. The cellular viability was assayed at 0, 15, 30, 90 and 110 days. The cellular viability did not differ statistically among the treatments up to 30 days of storage, with the median viability of 89.10%. The average viability found at 90 days (72.20%) was lower than in the first three storage periods. After 110 days, the average viability was 61.14%. In conclusion, since yeast cells were viable up to 110 days in storage on corn grains, these can be used as a vehicle for the application of yeast as a probiotic. |

| Excessive and inappropriate application of industrial N fertilizer can result in severe environmental and ecological problems, but whether the input of N fertilizer could affect the composition of mineral elements in corn has not been reported. Effects of input of N fertilizer on the composition of mineral elements (Se, Mo, I, Mn, Fe, Cu, Zn, Ca, Cr, K, Na, and Mg), in corn grain were investigated by ICP-MS (inductive coupling plasma-mass spectrometry). Se, I, Mn, Fe, Zn, Cr, K and Ca were significantly lower in the treatments with N fertilizer compared to a control without N fertilizer. There was a significant negative conrrelation (R) between four mineral elements and N fertilizer input: I, -0.71; Zn, -0.65; Ca, -0.75; K, -0.89. Therefore appropriate... |
