Abstract

In this study, 18 homemade cow and sheep yoghurt samples were collected from different
regions of Bulgaria for isolation and screening of lactic acid bacteria for antimicrobial activity.
Totally 17 strains were isolated and identified as Lactobacillus spp. based on their growth,
Gram stain, catalase and oxidase activity. The isolates were examined for their antibacterial
activity against Bacillus subtilis, Bacillus cereus and Escherichia coli using well diffusion
method. Six strains showed inhibitory activity against Gram-negative E. coli and only one
against Gram- positive B. subtilis and B. cereus using neutralized cell free cultures supernatants.
The results of the present study indicate that Bulgarian homemade yoghurts are potential source
of functional starter cultures for production of dairy products.
Key words: homemade yogurt, functional starter cultures, Lactobacillus spp., antibacterial activity
