Objective(s): Several beneficial effects have been attributed to the probiotic lactic acid bacteria. It was determined that lactobacilli can exert antiproliferative effects on the various cancer cell lines including colon cancer. Effects of lactic acid bacteria on colon cancer may vary from strain to strain and there is a need to find the new probiotic strains with tumor suppressing properties ...

Podosphaera fusca is the main causal agent of cucurbit powdery mildew in Spain. Four Bacillus subtilis strains, UMAF6614, UMAF6619, UMAF6639, and UMAF8561, with proven ability to suppress the disease on melon in detached leaf and seedling assays, were subjected to further analyses to elucidate the mode of action involved in their biocontrol performance. Cell-free supernatants showed antifungal ...

ABSTRACT- Lactic acid bacteria are commonly found in the gastrointestinal tract of various endothermic animals and humans, in milk, dairy and seafood products and on some plant surfaces. The aim of this study was to investigate the inhibitory effect of isolated lactic acid bacteria from intestines of narrow-barred Spanish mackerel (Scomberomorus commerson) on Listeria innocua growth. Five strai...

Staphylococcus aureus, as a foodborne pathogen causing significant harm worldwide, was studied to assess the effectiveness of probiotic strains Lactobacillus casei, plantarum, and Bifidobacterium bifidum individually collectively (as consortia) in controlling its growth. The growth patterns S. aureus were observed when co-cultured with each strain consortium all three over 72 hours. Additionall...
