Abstract

Tropical fruit and their industrial processing byproducts have been considered sources of probiotic Lactobacillus. Sixteen tropical fruit-derived Lactobacillus strains were assessed for growth-promoting effects using a host-commensal nutrient scarcity model with Drosophila melanogaster (Dm). Two Lactobacillus strains (L. plantarum 49 and L. plantarum 201) presenting the most significant effects (p ≤ .005) on Dm growth were selected and evaluated for their safety and beneficial effects in adult male Wistar rats during 28 days of administration of 9 log CFU/day, followed by 14 days of wash-out. Daily administration of L. plantarum 49 and L. plantarum 201 did not affect (p > .05) food intake or morphometric parameters. Both strains were associated with reduction (p ≤ .05) in blood glucose levels after 28 days of administration and after wash-out period; glucose levels remained reduced only in the group that received L. plantarum 49. Both strains were able to reduce (p ≤ .05) total cholesterol levels after 14 days of administration; after the wash-out period these levels remained reduced only in the group that received L. plantarum 201. L. plantarum 49 and L. plantarum 201 were detected in the intestine and did not cause alteration or translocate to spleen, kidneys or liver during the experimental or wash-out period. These results indicate that L. plantarum 49 and L. plantarum 201 present potential for use as probiotics with intrinsic abilities to modulate biochemical parameters of interest for the management of metabolic diseases.
