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 ...
