Fumonisins, being common in occurrence in maize-based feeds, pose a great threat to animal and human health. The present study is aimed at determining the antifungal activity of Lactobacillus plantarum MYS6 against a fumonisin producing fungus, Fusarium proliferatum MYS9. The isolate was subjected to standard tests for determining its probiotic attributes and antifungal properties. L. plantarum...

Here, plantaricin UG1 was shown to inhibit Listeria monocytogenes LMG10470 (L. monocytogenes) cells. The inhibition was not caused by lactic acid produced by the bacteriocin producing strain Lactobacillus plantarum UG1 (Lact. plantarum). Partially purified plantaricin UG1 had a higher antilisterial activity than Lact. plantarum cells in both Zabady and Kareesh cheese samples during their matura...

The lactic acid bacteria (LAB) involved during the spontaneous fermentation of cereals (maize,millet, sorghum) for the production of indigenous foods (‘akamu’, ‘kunu-zaki’) were quantified and identified. The lactic acid bacteria counts varied during the fermentation of the cereals while the titratable acidity (TTA) increased with reduction in pH. Identification of isolates using API 50CHL syst...

The aim of this study was to investigate the impact of consuming dairy yogurt containing Lactobacillus paracasei ssp. paracasei (L. paracasei), Bifidobacterium animalis ssp. lactis (B. lactis) and heat-treated Lactobacillus plantarum (L. plantarum) on immune function. A randomized, open-label, placebo-controlled study was conducted on 200 nondiabetic subjects. Over a twelve-week period, the tes...

The aim of this study was to evaluate the survivability of three probiotic strains Lactobacillus plantarum, Lactobacillus casei and Bifidobaterium bifidum in ice cream using microencapsulation by calcium alginate and whey protein concentrate. Also, the effect of different prebiotics (inulin, lactulose and Fructooligosaccharides) was studied. Six types of synbiotic ice cream containing free and ...

The method previously developed by us for the pure-culture fermentation of brined cucumbers and other vegetables has been applied successfully to Manzanillo variety olives. Field-run grade fruit was processed first by conventional procedures to remove most of the bitterness. Then the relative abilities of Lactobacillus plantarum, L. brevis, Pediococcus cerevisiae, and Leuconostoc mesenteroides ...

A global model of the lactic fermentation step of gowé was developed by assembling blocks hosting models for bacterial growth, lactic acid production, and the drop of pH during fermentation. Commercial strains of Lactobacillus brevis and of Lactobacillus plantarum were used; their growth was modeled using Rosso's primary model and the gamma concept as a secondary model. The optimum values of pH...

Antimicrobial activity and antibiotic susceptibility were tested for 23 Lactobacillus and three Bifidobacterium strains isolated from different ecological niches. Agar-well diffusion method was used to test the antagonistic effect (against Staphylococcus aureus, Escherichia coli, Bacillus cereus and Candida albicans) of acid and neutralized (pH 5.5) lyophilized concentrated supernatants (cell-f...

BACKGROUND Tannase is an enzyme that catalyses the breakdown of ester bonds in gallotannins such as tannic acid. In recent years, the interest on bacterial tannases has increased because of its wide applications. The lactic acid bacteria (LAB) plays an important role in food tannin biotransformation, it has the ability of hydrolyse tannins in ruminants intestine. The finding of tannin hydrolysi...

Intestinal mucosal scrapings (48) were collected from twelve, 6 month old, Large White Yorkshire pigs after slaughter. Isolates (23) that were gram positive rods, were alone subjected to physiological tests (growth at pH: 4.5, 9.5; temperature; 15, 45°C; and NaCl: 2, 6.5%), four isolates exhibited no growth at all conditions studied and were rejected. Biochemical tests on the remaining nineteen...
