Selection and assessment of the combination between waste of tropical fruits and probiotic strains in the modulation of intestinal microbiota of obese compared to the normal weight using the simulator of the human intestinal microbial ecosystem


The obesity has been considered, nowadays, one of the most frequent pathologies and, its etiology and treatment is related to lifestyle and eating habits. Prebiotics and bioactive compounds, present in tropical fruits wastes, have the potential to promote the modulation of intestinal microbiota, providing many benefits to the host's health, including the reduction obesity risk. On the other hand, the consumption of probiotics in synbiotic associations have demonstrated the beneficial effect on gut health, assisting the intestinal microbiota homeostasis. The aim of this work is to select a synbiotic combination of certain waste of tropical fruits with some probiotic strains, which positively influence the metabolism and the population of normal and obese microbiota, using a Simulator of Human Intestinal Microbial Ecosystem (SHIME). This project will be carried out in three steps. Step 1: It will be performed the viability analysis of three probiotic strains (L. paracasei 431, Bifidobacterium longum BB46 and L. acidophilus LA5) in combination with two waste of tropical fruits (camu-camu and acerola) and commercial pectin using an in vitro system (in batch). The combinations with the best viability, will have it's action, under the intestinal microbiota of normal individuals, tested in SEMH (Step 2). Step 3: The synbiotic combination with the best result in step 2, will have it's action, in the intestinal microbiota of obese individuals, tested in the SHIME. In this step, in addition to the same analysis performed in the second stage of study (ammonia, short chain fatty acids and microbiology dependent cultivation) it will be also realized, both in obese and eutrophic microbiota (control), analysis of the gut microbial diversity, using no dependent methods of cultivation: PCR and sequencing mass rRNA 16S gene using the Illumina HiSeq® platform on each trial.
