Gleaning evolutionary insights from the genome sequence of a probiotic yeast Saccharomyces boulardii

چکیده
BACKGROUND The yeast Saccharomyces boulardii is used worldwide as a probiotic to alleviate the effects of several gastrointestinal diseases and control antibiotics-associated diarrhea. While many studies report the probiotic effects of S. boulardii, no genome information for this yeast is currently available in the public domain. RESULTS We report the 11.4 Mbp draft genome of this probiotic yeast. The draft genome was obtained by assembling Roche 454 FLX + shotgun data into 194 contigs with an N50 of 251 Kbp. We compare our draft genome with all other Saccharomyces cerevisiae genomes. CONCLUSIONS Our analysis confirms the close similarity of S. boulardii to S. cerevisiae strains and provides a framework to understand the probiotic effects of this yeast, which exhibits unique physiological and metabolic properties.

متن کاملGenotypic and physiological characterization of Saccharomyces boulardii, the probiotic strain of Saccharomyces cerevisiae.
Saccharomyces boulardii, a yeast that was isolated from fruit in Indochina, has been used as a remedy for diarrhea since 1950 and is now a commercially available treatment throughout Europe, Africa, and South America. Though initially classified as a separate species of Saccharomyces, recent publications have shown that the genome of S. boulardii is so similar to Saccharomyces cerevisiae that t...

Background and Objective: The use of high amounts of a variety of antifungal drugs for treatment of Candida albicans infections is effective in inducing resistance to these drugs. Saccharomyces boulardii is a non-pathogenic yeast used as a probiotic in prevention and treatment of diarrhea diseases. There is evidence of the inhibitory effect of this yeast on Candida albicans virulence factors. ...

ABSTRACT: This study was aimed at probiotication of tomato and carrot juices using Lactobacillus plantarum, Lb. fermentum, Lb. casei, Lysinibacillus sphaericus and Saccharomyces boulardii. To enhance the stability, the probiotic cultures were micro-encapsulated using alginate coated chitosan beads. Tomato and carrot juice samples were pasteurized for 20 min at 63 °C. Lb. fermentum, Lb. plantara...
