Total soluble peptide profile of soybean meal when fermented with different bacterial isolates at 24 and 48 h. a Bacteria isolated from fermented food sources. b Bacteria isolated from grass carp fish. Coomassie Blue staining representing the peptide profile. In Panel a, lane 1 = unfermented soybean meal, lane 2 = Isolate-8 at 24 h, lane 3 = Isolate-8 at 48 h, lane 4 = Isolate-7 at 24 h, lane 5 = Isolate-7 at 48 h, lane 6 = Isolate-2 at 24 h, lane 7 = Isolate-2 at 48 h, lane 8 = Isolate-4 at 24 h, lane 9 = Isolate-4 at 48 h, lane 10 = marker. In Panel b, lane 1 = unfermented soybean meal, lane 2 = F-8 at 24 h, lane 3 = F-8 at 48 h, lane 4 = F-9 at 24 h, lane 5 = F-9 at 48 h, lane 6 = F-11 at 24 h, lane 7 = F-11 at 48 h, lane 10 = marker
