H. El-nezami et al., Ability of Lactobacillus and Propionibacterium strains to remove aflatoxinB-1 from the chicken duodenum, J FOOD PROT, 63(4), 2000, pp. 549-552
The ability of Lactobacillus rhamnosus strains GG and LC-705 to remove AFB(
1) from the intestinal luminal liquid medium has been tested in vivo using
a chicken intestinal loop technique. In this study, the GG strain of L. rha
mnosus decreased AFB(1) concentration by 54% in the soluble fraction of the
luminal fluid within 1 min. This strain was more efficient in binding AFB(
1) compared with L. rhamnosus strain LC-705 (P < 0.05) that removed 44% of
AFB(1) under similar conditions. Accumulation of AFB(1) into the intestinal
tissue was also determined. There was a 74% reduction in the uptake of AFB
(1) by the intestinal tissue, in the presence of L. rhamnosus strain GG com
pared with 63% and 37% in the case of propionibacterium freudenreichii ssp.
shermanii JS and L. rhamnosus strain LC-705, respectively, The complexes f
ormed in vitro between either L. rhamnosus strain GG or L, rhamnosus strain
LC-705 and AFB(1) were stable under the luminal conditions for a period of
1 h.
