Antibacterial activity of the bacteriocins producing- lactic acid bacteria isolated from some processed meat products against selected indicator bacterial strains

A Study on the Antibacterial Activity of Lactic Acid Bacteria Isolated from Traditional Iranian Milk Samples

198 Lactic acid bacteria (LAB) were isolated from Iranian milk samples. Almost all isolatedLAB showed inhibitory activity towards E. coli and S. aureus as Gram negative and Grampositive indicators, respectively. No role was observed for hydrogen peroxide in the activity ofall isolated strains while organic acids proved a prominent role in all detected inhibitoryactivities. Within isolated LAB, ...

Probiotic potential of thermotolerant lactic acid bacteria strains isolated from cooked meat products

Ten thermotolerant lactic acid bacteria Pediococcus pentosaceus (4 strains), Lactobacillus plantarum (3 strains), Enterococcus faecium (2 strains) and Aerococcus viridans (1 strains) – isolated from cooked meat products were evaluated to identify their probiotic properties, including tolerance to low pH, tolerance to taurocholic acid and bile, coaggregation, autoaggregation and adherence to HEp...

Antimicrobial effects of bacteriocins producing lactic acid bacteria isolated from plant origin

Antibacterial Activity of Some Lactic Acid Bacteria Isolated from an Algerian Dairy Product

In the present study, the antibacterial effect of 20 lactic acid bacteria isolates from a traditional cheese was investigated. 6 isolates showed antibacterial effect against Gram positive bacteria. Streptococcus thermophilus T2 strain showed the wide inhibitory spectrum against the Gram positive bacteria. Growth and bacteriocin production profiles showed that the maximal bacteriocin production,...

Screening of antibacterial activity of lactic acid bacteria isolated from fermented vegetables against food borne pathogens

This study aims to screen the antibacterial activity of lactic acid bacteria (LAB) isolated from home-made fermented vegetables against common food borne pathogens. The antagonistic properties of these isolates against Escherichia coli, Staphylococcus aureus, Yersinia enterocolitica and Bacillus cereus were examined using agar well diffusion method. Four LAB namely MF6, MF10, MF13, and MF15 ide...
