1. Effects of pine honey on the physicochemical, microbiological and sensory properties of probiotic yoghurt
Abstract In this study, physicochemical, microbiological and sensory properties of probiotic yoghurt samples added different rates (2%, 4% and 6%) of pine honey on days 1, 7, 14, 21 of refrigerated storage were investigated. pH, serum separation values, water holding capacity decreased and titratable acidity increased with increasing the ratio of the added h

3. Growth kinetic models of five species of Lactobacilli and lactose consumption in batch submerged culture
Abstract Kinetic behaviors of five Lactobacillus strains were investigated with Contois and Exponential models. Awareness of kinetic behavior of microorganisms is essential for their industrial process design and scale up. The consistency of experimental data was evaluated using Excel software. L. bulgaricus was introduced as the most efficient strain with t

4. A functional food: a traditional Tarhana fermentation
Abstract White wheat flour, concentrated full fat yoghurt, tomato paste, onion, red and green paprika, and mint and salt are used in the preparation of Tarhana. During the 7-day Tarhana fermentation period, the acidity increased from 1.10% to 3.25%, the pH decreased from 5.22 to 4.13, and the moisture decreased from 70.12% to 26.15%. The chemical composition

7. Efeito do sobrenadante de isolados de Lactobacillus sp. sobre Escherichia coli O157:H7 reforça o papel da produção de ácidos orgânicos como fator de controle patogênico
Muitas tentativas têm sido feitas para se estabelecer o controle de patógenos de origem alimentar através do uso de estirpes de Lactobacillus e dos seus produtos de metabolismo, com sucesso sendo sucedido em várias situações. O objetivo deste trabalho foi investigar o efeito antagônico do sobrenadante de culturas de oito isolados de Lactobacillus, inc

8. Activity of encapsulated Lactobacillus bulgaricus in alginate-whey protein microspheres
In this work, alginate-whey protein was used as wall materials for encapsulating Lactobacillus delbrueckii subsp. bulgaricus (L. bulgaricus). The characteristics of encapsulated and free L. bulgaricus showed that the free L. bulgaricus lost viability after 1 min exposure to simulated gastric fluid (SGF) at pH 2.0 and 2.5. However, the viability of encapsulat

9. Characterization of goat milk and potentially symbiotic non-fat yogurt
Combining prebiotics and probiotic microorganisms improve quality in the formulation of foods. In this paper, the characteristics of goat milk and symbiotic yogurt were studied. Raw goat milk was analyzed and the skimming process was optimized. For the formulation of a potentially non-fat symbiotic yogurt made with skimmed goat milk, inulin, gelatin, sugar,

10. Mixed Cultures Fermentation for the Production of Poly-ß-hydroxybutyrate
Poly-ß-hydroxybutyrate (PHB) is a biodegradable intracellular microbial product produced by many bacteria and it is comparable to some of the petrochemical derived thermoplastics such as polypropylene. One of the main barriers for the commercial exploitation is the high cost of the substrate for the production of biopolymer. The utilization of mixed microbi

12. Effect of probiotics on the development of dimethylhydrazine-induced preneoplastic lesions in the mice colon
PURPOSE: To determine the effect of probiotics on the development of chemically induced (1, 2-dimethylhydrazine) colonic preneoplastic lesions, in mice. METHODS: The animals were divided into five groups. The control group was injected with carcinogen alone and the other groups also received probiotics (1- Lactobacillus delbrueckii UFV-H2b20; 2- Bifidobacter
