Recent studies have evaluated the impact of alternatives to antibiotic growth promoters (AGPs) such as phytogenic feed additives (PFAs) in vitro and in vivo. Zhou and colleagues studied the antibacterial properties of 30 herbs on pathogenic Gram-negative and positive bacteria (1). Thirteen of the 30 herbs exerted a significant effect against Escherichia coli ATCC 25922 (p < 0.01, n = 11 and p <...

Selenium (Se) is considered as an essential element for human body. Selenized probiotic fermented milk drink (DOOGH) as a functional beverage to increase Se available in body. The predominate sugar, protein and mineral ion of Iranian yoghurt drink (DOOGH) are lactose, casein and calcium, respectively. Different levels of  Selenium (2.5 – 3- 3,5-  4 and 4.5) is prepared and its suitability based...

The objective of this study was to identify Acinetobacter in a traditional cheese from west Azarbaijan, Iran, and to study the lipolytic and proteolytic activities of these bacteria in ripening of white brine cheese. Acinetobacter is a gram negative bacteria which can be found in different sources as dairy products. Lypolysis and proteolysis characteristic of this bacteria and...

Sauerkraut fermentations rely upon selection of naturally occurring lactic acid bacteria by addition of 2.0% to 2.25% granulated sodium chloride (NaCl) to shredded cabbage. Excess brine generated is a waste product with high levels of organic material (BOD) and nonbiodegradable NaCl. The objective was to determine whether addition of Leuconostoc mesenteroides starter culture to reduced-salt cab...

The objective of this study was to identify lactic acid bacteria (LAB) isolated from kimchi and to evaluate its characteristics and functional properties for application in fermented dairy products as a probiotic or commercial starter culture. Eight stains isolated from kimchi were selected through an investigation of phenotypic characteristics. Two strains (DK211 and DK303) were identified as ...

In this study, the effects of proteolytic activity of yogurt starter bacteria on physicochemical and technological properties of yogurt were investigated. Moreover, impact of proteolytic activity and production of exopolysaccharide (EPS) on the performance of each strain were screened. In order to compare the textural properties of yogurt samples, four parameters were evaluated: syneresis, wate...

Salt rising bread (SRB) is an Appalachian traditional bread made without yeast, using a starter derived from flour, milk and potatoes. The “rising agent” has been identified as Clostridium perfringens, not salt, and is presumably derived from the environment. Although no cases of illness have been attributed to SRB, C. perfringens type A is a common cause of food poisoning from meats and gravie...

Increasing incidence of food-borne disease along with its social and economic consequences have led to conducting extensive research in order to produce safer food and develop new antimicrobial agents; among them, extensive use of probiotics and bacteriocins as biological additives is of significant importance. The aim of the present study was to evaluate the interactions (growth behavior and s...

The effect of adding Saccharomyces boullardii in soya yoghurt was studied. control made with milk and traditional starter culture (Lactobacillus bulgaricus Streptococcus thermophilus) while the other three treatments were by 1%, 2%, 3% S. boulardii starter. Proximate composition all determined after fermentation time. Shelf-life evaluation treatment observed during storage During proximate eval...
