Probiotics as an Alternative to Antibiotics: Genomic and Physiological Characterization of Aerobic Spore Formers from the Human Intestine

Maria Vittoria,
Anella Saggese,
Rachele Isticato
et al.

Abstract: A total of thirty-two aerobic spore former strains were isolated from intestinal samples of healthy children and analyzed for their hemolytic and antibiotic-resistant activities. Four strains selected as non-hemolytic and sensitive to all antibiotics recommended as relevant by regulatory agencies were short-listed and evaluated for their in silico and in vitro probiotic potentials. The four selected strains were assigned to the Bacillus velezensis (MV4 and MV11), B. subtilis (MV24), and Priestia megaterium (fo… Show more

“…Importantly, several B. velezensis strains (e.g., strains LOH112, ADS024, Marseille-Q1230, MV4, and MV11) have been isolated from human stool and cervicovaginal samples, suggesting that B. velezensis naturally occurs in the human gut and vaginal microbiotas [ 57 , 58 , 59 , 60 ]. B. velezensis strains secrete a wide array of bioactive molecules, including antimicrobial metabolites such as macrolactin, antimicrobial lipopeptides like fengycin, and digestive enzymes [ 61 ].…”
