In this study, yoghurt was produced from camel (Camelus dramedarius) milk with whey protein isolate (3 % w/v) and fortified with 3 % (w/v) traditional samphire molasses (TSM) (YTSM), 3 % (w/v) TSM+0.1% (w/v) κ-carrageenan (YTSMC) or 3 % (w/v) TSM+0.05 % (w/v) xanthan gum (YTSMX). In yoghurt samples, physical-chemical properties, texture, color and sensory analysis were determined on the 1st, 5t...

The peptidases of thermophilic lactic acid bacteria have a key role in the proteolysis of Swiss cheeses during warm room ripening. To compare their peptidase activities toward a dairy substrate, a tryptic/chymotryptic hydrolysate of purified beta-casein was used. Thirty-four peptides from 3 to 35 amino acids, including three phosphorylated peptides, constitute the beta-casein hydrolysate, as sh...

Lactobacillus delbrueckii subsp. bulgaricus is one of the most widely used starter culture strains in industrial fermented dairy manufacture. It is also common in naturally fermented dairy foods made using traditional methods. The subsp. bulgaricus strains found in naturally fermented foods may be useful for improving current industrial starter cultures; however, little is known regarding its g...

The genetic determinants for lactose utilization from Lactobacillus delbrueckii subsp. bulgaricus ATCC 11842 and galactose utilization from Lactococcus lactis subsp. cremoris MG 1363 were heterologously expressed in the lysine-overproducing strain Corynebacterium glutamicum ATCC 21253. The C. glutamicum strains expressing the lactose permease and beta-galactosidase genes of L. delbrueckii subsp...

The complete genome sequence of Lactobacillus bacteriophage LL-H was determined in 1996. Accordingly, LL-H has been used as a model phage for the infection of dairy Lactobacillus, specifically for thermophilic Lactobacillus delbrueckii ssp. lactis host strains, such as ATCC 15808. One of the major goals of phage LL-H research consisted of the characterization of the first phage-host interaction...

background and aims: probiotics are defined as live microorganisms that are beneficial to human health. probiotics are commonly found in some foods such as dairy products or complementary tablets. a recent research shows that probiotics have a significant role in diabetes type 1 and 2 treatment. among the variety of lactic acid bacteria, lactobacillus strains are well known in probiotics for th...
