3. Results and discussion
Table 1 shows the AFB1 concentrations in the binding assays
with SC-based products containing heat-killed cells in PBS during
contact times of 5, 10, 20 and 30 min. Lower AFB1 levels were found
in PBS (spiked with 0.5 mg AFB1 mL1
) after treatment with dried
yeast from sugar cane (DY) cells (1 g, 1010 cells mL1
), with values
ranging from not detected (LOD: 0.01 mg mL1
) to
0.035 ± 0.002 mg mL1
. The second best response was achieved
using the autolyzed yeast from sugar cane (AY), with AFB1
remaining in PBS at levels from 0.025 ± 0.006 to
0.096 ± 0.005 mg mL1
