BACKGROUND The beneficial effects of Lactobacillus species have been reported but the role of these species including Lactobacillus casei (L. casei) on oral health is not well documented. The purpose of this study was to evaluate the effects of conventional or probiotic cheese containing L.casei on salivary Streptococcus mutans (SM) and Lactobacilli levels. METHODS In this double-blind contro...

Probiotic strains require investigation to obtain functional products and to satisfy the increasing market demand for probiotics. Traditional fermented yak milk is a potential source of probiotic Lactobacillus strains. Lactobacillus isolates were identified on the basis of their physiological and biochemical characteristics and their probiotic properties were evaluated, including acidifying and...

in this study, production of fermented functional beverage based on the mixture of carrot, beet and apple juices using the lactobacillus casei was carried out. factors of consumption of reduction sugars, brix and bacterial growth were examined after fermentation and during the storage for 28 days and at 4˚c. to produce probiotic fermented mixture of carrot, beet and apple juices and lactobacill...

background: the present work was planned to evaluate the antihyperglycemic, lipid‑lowering, and antioxidant effect of lactobacillus casei and bifidobacterium bifidum in streptozotocin (stz)‑induced diabetic rats. methods: single daily dose of 1 × 107 cfu/ml of l. casei and b. bifidum alone and in combination of both was given to wistar rats orally by gavaging for 28 days. glucose tolerance test...

Raman scattering and its particular effect, surface-enhanced Raman scattering (SERS), are whole-organism fingerprinting spectroscopic techniques that gain more and more popularity in bacterial detection. In this work, two relevant Gram-positive bacteria species, Lactobacillus casei (L. casei) and Listeria monocytogenes (L. monocytogenes) were characterized based on their Raman and SERS spectral...

Antisera prepared against two isologous malic enzymes from Lactobacillus casei strains 64H and M40 were used to survey and categorize the various malic enzymes found within this diverse species. In addition to detecting three major antigenic variants of malic enzyme within this group, both antisera readily reacted with Streptococcus faecalis malic enzyme. The cross-reactions between the L. case...

BACKGROUND Physiological stressors may alter susceptibility of the host intestinal epithelium to infection by enteric pathogens. In the current study, cytotoxic effect, adhesion and invasion of Salmonella enterica serovar Typhimurium (S. Typhimurium) to Caco-2 cells exposed to thermal stress (41 degrees C, 1 h) was investigated. Probiotic bacteria have been shown to reduce interaction of pathog...

The cbsA gene encoding the collagen-binding S-layer protein of Lactobacillus crispatus JCM5810 was expressed in L. casei ATCC 393(T). The S-protein was not retained on the surface of the recombinant bacteria but was secreted into the medium. By translational fusion of CbsA to the cell wall sorting signal of the proteinase, PrtP, of L. casei, CbsA was presented at the surface, rendering the tran...

Abstract Products containing beneficial bacteria for humans have been widely used recently. The in these products generally belong to the genus Lactobacillus. Among species of this genus, Lactobacillus casei attracts a lot interest due their valuable properties. With properties, many L.casei strains can be as probiotics. Based on recommendation FAO/WHO probiotic bacteria, our study strain LC 30...
