Inhibitory activity of Saccharomyces cerevisiae, Rhodotorulaglutinis and Lactobacillus spp against Escherichia coli isolated from children diarrhea infection

Abstract

The study was conducted to demonstrate the inhibitory activity of Yeast and Lactobacillus spp. Escherichia coli isolated from children's diarrhea Infection. Yeast isolates of Saccharomyces cerevisiae were isolated from dried date, Rhodotorulaglutinis was isolated from apple fruit. Pure cultures were prepared on Sabouraud's dextrose agar (SDA). Lactobacillus spp. were obtained from Lacteol fort Sachets. A yeast and Lactobacillus spp isolates have been prepared and its antibacterial activity against E. coli. Our Results show variable effectiveness were observed, Lactobacillus spp had the highest inhibitory activity against E. coli, while Yeast interaction that the highest Inhibitory activity from yeast signal against E. coli.In conclusion: the results of S. cerevisiae, Rh.glutinis and Lactobacillus spp isolates showed inhibitory activity against E. coli.
