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...

This study aimed to isolate and characterize viable lactic acid bacteria (LAB) from the most popular in Bulgaria fermented milk products. Different samples from home-made cheeses, yoghurt and katak, from ecological regions of Stara Planina, Rila and Rodopi mountains were collected. A total of 25 LAB cultures (coci and rods) were isolated and polyphasic taxonomic characterization was performed. ...

Fermentation of shrimp biowaste was conducted with two Lactobacillus plantarum strains at pH=6.0 under various salt concentrations. The non-amylolytic strain L. plantarum 541 and amylolytic strain L. plantarum A6 showed to possess reasonable growth in biowaste with the addition of salt as high as 6 %. Fermentation carried with 10 % inoculum, 5 % glucose, with initial reduction of pH to 6.0 usin...

Lactobacillus plantarum LMG P-26358 isolated from a soft French artisanal cheese produces a potent class IIa bacteriocin with 100% homology to plantaricin 423 and bacteriocidal activity against Listeria innocua and Listeria monocytogenes. The bacteriocin was found to be highly stable at temperatures as high as 100°C and pH ranges from 1-10. While this relatively narrow spectrum bacteriocin also...
