Abstract

In order to determine the growth and fermentation capacity of Lactobacillus spp. and Bifidobacterium spp. in presence of dried extract of Agave fourcroydes (henequen) under in vitro conditions, three strains of Bifidobacterium (B. adolescentes, B. bifidum, B. breve) and three of Lactobacillus (L. acidophilus, L. casei, L. paracasei) were selected. The commercial prebiotics Raftilosa P95, Raftiline HP, and the dried
extract of A. fourcroydes, rich in oligosaccharides of fructans, were used as energy source. The MRS medium, without glucose, was used as control. Cysteine was added when necessary. Higher microbial growth (P < 0.001) and pH decrease in the medium (P < 0.001) were obtained in all the groups of bacteria in presence of dried extract of A. fourcroydes. It was superior to the sources of commercial fructans under use, with high production of organic acids. The lactic acid bacteria fermented efficiently the dried extract of A. fourcroydes, thereby being a proper probiotic candidate to be used in animal feeding. These results could generate further studies with the aim of obtaining new functional feeds, such as the symbiotics, which would enhance the effects.
Key words: fructans, prebiotic, lactobacilli, bifidobacteria, Agave fourcroydes.
