AB  - The objective of this study was to evaluate the efficacy of two adsorbents, a raw bentonite clay (RC) and a concentrated bentonite clay (CC), in ameliorating the toxic effects of aflatoxin B1 (AFB1). Results of the in vitro study (pH 3.0) indicated the CC adsorbed more AFB1 than RC (93.39 mg/g vs. 79.30 mg/g) suggesting that CC may be more effective than RC in reducing the toxic effects of AFB1. One hundred and eighty day-old straight run broiler chicks were assigned to 6 replicate pens of 5 chicks each and assigned to 6 dietary treatments from hatch to day 21. Dietary treatments included: 1) basal diet (BD) containing no AFB1 or adsorbents; 2) BD plus 0.50% RC; 3) BD plus 0.50% CC; 4) BD plus 2.0 mg AFB1/kg; 5) BD plus 2.0 mg AFB1/kg plus 0.50% RC; and 6) BD plus 2.0 mg AFB 1/kg plus 0.50% CC. Dietary AFB1 concentrations were confirmed by analysis and diets were screened for other mycotoxins prior to the start of the experiment. The addition of AFB1 to the feed reduced (P  LT  0.05) growth performance and increased (P  LT  0.05) relative liver weight (RLW) and kidney weight (RKW) of chicks fed AFB1 compared to control chicks on day 21. These changes were ameliorated (P  LT  0.05) by the addition of RC and CC to the AFB1 diet. Mild to moderate lesions of aflatoxicosis (2.25) were observed in chicks fed AFB1 alone on day 21. The addition of both RC and CC to the AFB1 diet decreased (P  LT  0.05) but did not prevent liver lesions (0.92 and 1.42, respectively). Results indicate that both RC and CC were effective in reducing the toxic effects of AFB1, however the cost of processing of CC would make the RC a more economical product for reducing the effects of AFB1 in young broiler chicks.

AB  - In vitro tests were performed to determine the ability of beer fermentation residue (BFR) containing Saccharomyces cerevisiae to bind aflatoxin B-1 (AFB(1)), zearalenone (ZEA), ochratoxin A (OTA) and deoxynivalenol (DON). BFR was obtained from a microbrewery, dried and ground, resulting in approximately 1.0 x 10(10) S. cerevisiae cells g(-1) BFR. Binding assays consisted of suspending BFR (100 mg) in 10 mL of buffer solution (pH 3.0 or 6.5) spiked with AFB(1), ZEA, OTA or DON (2.0 mu g ml(-1) of each mycotoxin), incubation (60 min, 25 degrees C) followed by centrifugation. The supernatants were analyzed by high performance liquid chromatography. BFR had higher binding capacity for ZEA (75.1% and 77.5% at pH 3.0 and 6.5, respectively), when compared with AFB(1), OTA and DON (less than 60% and 40% at pH 3.0 and 6.5, respectively). BFR also produced linear isotherms for ZEA at both pH values, hence indicating a potential application of industrial fermentation by-products containing yeast cells in reducing the bioavailability of ZEA in contaminated feedstuffs. However, in vivo studies are required to prove its efficacy in livestock and poultry.

AB  - The aim of this study was to determine the binding capacity of a hydrated sodium calcium aluminosilicate (HSCAS) for aflatoxin B-1 (AFB(1)), and the efficacy of the HSCAS to reduce the concentrations of residual AFB(1) and its metabolites in the liver and kidney of broilers fed AFB(1). One hundred 1-d-old male broilers (Ross 708) were maintained in chick batteries and allowed ad libitum access to feed and water. A completely randomized design was used with 5 replicate pens of 5 chicks assigned to each of 4 dietary treatments from hatch to 21 d. Dietary treatments included the following: A) basal diet (BD), with no HSCAS or AFB(1), B) BD supplemented with 0.5% HSCAS only, C) BD supplemented with 2.5 mg of AFB(1)/kg of feed, and D) BD supplemented with 2.5 mg of AFB(1)/kg of feed and 0.5% HSCAS. On d 21, 5 chicks from each treatment were anesthetized with carbon dioxide, killed by cervical dislocation, and samples of liver and kidney were collected for analysis of AFB(1) residues. The percentage of AFB(1) bound for each concentration of adsorbent (100, 10, 1, 0.5, 0.25, and 0.05 mg/10 mL) was 100, 91.1, 81.8, 75.4, 40.1, and 8.8%, respectively. Concentrations of aflatoxin residues (AFB(1), aflatoxicol, aflatoxins B-2 and G(1)) were lower (P  LT  0.05) in livers and kidneys of birds fed AFB(1) plus HSCAS (diet D), when compared with birds fed AFB(1) alone (diet C). However, histopathology data from the in vivo study indicated that HSCAS did not prevent lesions associated with aflatoxicosis. The decrease in the bioavailability of AFB(1) caused by the HSCAS reduced aflatoxin residues in liver and kidney, but not enough to completely prevent the toxic effects of AFB(1) in broilers.

AB  - A zinc-exchanged montmorillonite (Zn-MONT) was prepared from a natural montmorillonite (MONT) and the adsorption of aflatoxin B-1 (AFB(1)) was investigated at pH 3 and 7. Characterization of Zn-MONT was done by determination of chemical composition, the point of the zero charge (pH(pzc)), thermal (DTA/TGA/DTG) and X-ray powder diffraction (XRPD) analysis. Adsorption of AFB(1) (C-0 = 4 ppm) by Zn-MONT, at different solid/liquid ratios (10, 1 and 0.5 g L-1), at pH 3 or 7, showed that its adsorption was high (over 96%) and independent of pH, similar to MONT. No desorption of AFB(1) from MONT-AFB(1) and Zn-MONT-AFB(1) complexes occurred at pH 6.5, suggesting strong binding of AFB(1) by both adsorbents. Furthermore, AFB(1) adsorption by Zn-MONT followed a nonlinear (Langmuir) type of isotherm at pH 3 with a calculated maximum capacity of 60.17 mg g(-1). The stability of MONT-AFB(1) and Zn-MONT-AFB(1) complexes was evaluated by calculating the binding energies between AFB(1) and metal cations using quantum chemical methods. The evaluated interaction energies of AFB(1) with hydrated Zn2+, Mg2+, and Ca2+ cations showed that the strongest interaction was the interaction of the Zn2+ system, -70.2 kcal mol(-1), whereas energies for Mg-2 and Ca2+ systems were -68.8 and -62.9 kcal mol(-1), respectively. The results indicate that Zn-MONT can be suitable for potential practical application as both, an antibacterial and an aflatoxin binding agent.

AB  - Adsorption of aflatoxin B-1 (AFB1) by natural montmorillonite (MONT) and montmorillonite modified with copper ions (Cu-MONT) was investigated. Both MONTs were characterized using the X-ray powder diffraction (XRPD) analysis, thermal analysis (DTA/TGA) and scanning electron miscroscopy/electron dispersive spectroscopy (SEM/EDS). The results of XRPD and SEM/EDS analyses of Cu-MONT suggested partial ion exchange of native inorganic cations in MONT with copper occurred. Investigation of AFB1 adsorption by MONT and Cu-MONT, at pH 3, 7 or 9, showed that adsorption of this toxin by both MONTs was high (over 93%). Since AFB1 is nonionizable, no differences in AFB1 adsorption by both MONTs, at different pHs, were observed, as expected. Futhermore, it was determined that adsorption of AFB1 by both MONTs followed a non-linear (Langmuir) type of isotherm, at pH 3. The calculated maximum adsorbed amounts of AFB1 by MONT (40.982 mg/g) and Cu-MONT (66.225 mg/g), derived from Langmuir plots of isotherms, indicate that Cu-MONT was much effective in adsorbing AFB1. Since, the main cation in an exchangeable position in MONT is calcium, and in Cu-MONT both calcium and copper, the fact that ion exchange of inorganic cations in MONT with copper increases adsorption of AFB1 suggests that additional interactions between AFB1 and copper ions in Cu-MONT caused greater adsorption.
