| The effects of enzyme complex SSF (solid state fermentation) on growth performance and the availability of sucrose and monosaccharides in the chyme of Nile were involved. The study included 360 fish (70g±4.43) in a completely randomized design with six dietary treatments (0, 50, 100, 150, 200 and 250 ppm of SSF) arranged in six replicates, with 10 fish per replicate. Every 15 days, one tilapia of each experimental unit was sacrificed for analyses of carbohydrate in the chyme. On day 60 of the experiment, the performance parameters were measured. There was a linear effect according to treatment for final weight and weight gain. For the other performance parameters, there were no differences. There was quadratic effect for sucrose and glucose in function of... |

| Two α -galactosidase (P1 and P2) and one invertase present in the culture of Aspergillus terreus grown on wheat straw for 168 h at 28ºC were partially purified by gel filtration and hydrophobic interaction chromatographies. Optimum pH and temperatures for P1, P2 and invertase preparations were 4.5-5.0, 5.5 and 4.0 and 60, 55 and 65ºC, respectively. The K M app for Ï -nitrophenyl-α -D-galactopyranoside were 1.32 mM and 0.72 mM for P1 and P2, respectively, while the K M app value for invertase, using sacarose as a substrate was 15.66 mM. Enzyme preparations P1 and P2 maintained their activities after pre-incubation for 3 h at 50ºC and invertase maintained about 90% after 6 h at 55 ºC. P1 and P2 presented different inhibition sensitivities by Ag+,... |

| ABSTRACT The effects of processing of pelleted diets and their storage time on the stability of the enzyme complex SSF (solid-state fermentation) were evaluated. Two diets were formulated with the same nutritional composition, differing only in the Schizochytrium sp. levels (0 g kg-1 and 50 g kg-1). The samples were collected during the following processing steps: mixing, then pelleting, and then oven. To evaluate the storage time, the diet ready after drying was considered as day 1. On this day, two samples were obtained, being one kept in a room with ambient temperature of 25 °C and another stored in freezer at -18 °C. At 15, 30, 45, and 60 days, sub-samples were taken. All samples from the processing step and storage time were sent to the laboratory and... |
