Abstract

Friendly intestinal bacteria exert an important role in improving resistance to disease; but increased stress or consumption of antibiotic medications can lead to disturbance in balance of microflora. Probiotics used to return the balance between friendly bacteria and pathogenic bacteria in the gastrointestinal tract. Yogurt as a source of Lactic acid bacteria (LAB) or LAB mainly lactobacilli as probiotics have several therapeutic functions when administered as live microorganisms in adequate amounts. LAB strains have good potential for application in functional foods due to their Antioxidant activity. Antioxidants are necessary for preventing diseases induced by free radicals and called effective free radical scavengers. Aim of this study was to isolate strains from yoghurt and rayeb to evaluate their biotechnological potential including antimicrobial activity, antioxidant activity, bile salt hydrolase activity and probiotic potential. Statistical analyses were performed using SPSS at P < 0.05. A total of 50 bacterial strains were isolated from yoghurt and rayeb of 5 different companies (Almaraei, Nada, Nadec, Alsafi and Activia) and used to examine their probiotic properties, antioxidant activity, bile salt dehydrogenase activity and antimicrobial activity. Based on morphological characters, 20 isolates were designated as being catalase negative, and rod-shaped while only nine isolates showed positive reaction with both gram stain and lactic acid production. Accordingly, representative isolates (nine isolates) were considered as presumptive Lactobacillus species. Assessment of Survival in the Gastrointestinal Tract (probiotic potential) revealed that 4 bacterial strains were acid tolerance, Strain 2 was the most acid resistance of all isolates, survived over a period of 4 h at pH 3 (Survival rate was 68.22%), 3 strains were bile salt resistance after 4 hours that the Survival rate was more than 50%., only 2 strains from the previous strains had BSH activity and antioxidant activity. Therefore, these bacterial strains had the ability to survive conditions mimic those present in gastrointestinal tract and had probiotic potential. These strains isolated from yoghurt and Rayeb Almaraei. The result of comparison between companies indicates that the best company which use starter cultures with probiotic potential was Almaraei.
