Endogenous fatty acid biosynthesis in the bacterium Lactobacillus plantarum is greatly decreased upon addition of exogenous fatty acids (Henderson, T.A., and McNeil, J.J. (1966) Biochem. Biophys. Res. Commun. 25, 662-669). We have demonstrated the presence of five pantothenate-containing compounds in L. plantarum which have been identified by co-chromatography with authentic samples: pantothena...

The objective of this study was to evaluate the antioxidant capacity of Lactobacillus plantarum ZLP001 and its effects on growth performance and antioxidant status in weaning piglets. The survival in hydrogen peroxide and free radical-scavenging activity of Lactobacillus plantarum ZLP001 were analysed in vitro. The Lactobacillus plantarum ZLP001 showed high viability in 1.0 mmol/L hydrogen pero...

Nineteen strains of Lactobacillus isolated from goat's milk from farms in north-west of Algeria were characterized. Isolates were identified by phenotypic, physiological and genotypic methods and some of their important technological properties were studied. Phenotypic characterization was carried out by studying physiological, morphological characteristics and carbohydrate fermentation pattern...

The intestinal lactic acid microflora of the edible snail Cornu aspersum was studied by culture-based methods and was phenotypically and molecularly characterized. The antibacterial activity of lactic acid bacteria (LAB) isolates was investigated. Snails in different stages of development were collected from farms located in several regions of Bulgaria. One hundred twenty-two isolates, belongin...

Larval and adult fruit flies are attracted to volatiles emanating from food substrates that have been occupied by larvae. We tested whether such volatiles are emitted by the larval gut bacteria by conducting tests under bacteria-free (axenic) conditions. We also tested attraction to two bacteria species, Lactobacillus brevis, which we cultured from larvae in our lab, and L. plantarum, a common ...

The present study tested the persistence of orally administered bacteria in the gut of suckling mice. We used three bacterial strains: one strain of Lactobacillus johnsonii (designated strain Ms1) that was previously isolated from the mouse stomach, and two strains of L. plantarum, (strain No. 14 and JCM 1149(T)). We detected L. johnsonii Ms1, but neither strain of L. plantarum, in the gut 7 da...

Upon exposure to exogenous pediocin-like bacteriocins, immunity proteins specifically bind to the target receptor of the mannose phosphotransferase system components (man-PTS IIC and IID), therefore preventing bacterial cell death. However, the specific recognition of immunity proteins and its associated target receptors remains poorly understood. In this study, we constructed hybrid receptors ...

The ability of three known probiotic strains (two lactobacilli and one bifidobacterium) to ferment fructooligosaccharides (FOS) from yacon roots (Smallanthus sonchifolius Poepp. Endl) was compared to commercial FOS in this study. Results indicate that Lactobacillus acidophilus NRRL-1910, Lactobacillus plantarum NRRL B-4496, and Bifidobacterium bifidum ATCC 15696 were able to ferment yacon root ...

Lactic acid bacteria strains Lactobacillus plantarum CWBI-B534 and Leuconostoc ssp. mesenteroïdes (L. mesenteroïdes) Kenya MRog2 were produced in bioreactor, concentrated, with or without cryoprotectants. In general, viable population did not change significantly after freeze-drying (p > 0.05). In most cases, viable population for cells added with cryoprotectants was significantly lower than th...

Introduction: Alzheimer's disease (AD) is a neurodegenerative disorder, clinically characterized by memory dysfunction and progressive loss of cognition. No curative therapeutic or drug is available for the complete cure of this disease. The present study was aimed to evaluate the efficacy of Lactobacillus plantarum MTCC1325 in ATPases activity in the selected brain regions of rats induced with...
