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...

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...

Background: Probiotics are living organisms that are beneficial for human health. Lactobacillus species has been considered as probiotic bacteria due to their adjustment of human immune responses and therapeutic effects in inflammatory disorders. The aim of the present study was to evaluate the effects of Lactobacillus probiotic strains on toll-like receptors (TLR2 and TLR4) expression in HT29 ...

Because of the considerable differences in the reported values for serum folate in normal subjects using Lactobacillus casei as assay organism the effect of daylight when preparing media for this assay was studied. It was found that the growth properties of the medium were destroyed by direct sunlight and impaired by bright reflected sunlight, therefore reducing the sensitivity of the assay. Ad...

Direct assay of serum folate by mixing serum with a mixture of L. casei and medium without autoclaving was found to provide serum folate results similar to those by extraction of serum with heat. This procedure was found more reliable than that using the same technique with chloramphenicol and a strain of L. casei adapted to grow in this material. A portion of apparent folate activity assayed i...
