The Ghanaian cocoa bean heap fermentation process was studied through a multiphasic approach, encompassing both microbiological and metabolite target analyses. A culture-dependent (plating and incubation, followed by repetitive-sequence-based PCR analyses of picked-up colonies) and culture-independent (denaturing gradient gel electrophoresis [DGGE] of 16S rRNA gene amplicons, PCR-DGGE) approach...

BspA is a basic surface-exposed protein from Lactobacillus fermentum BR11. Sequence comparisons have shown that it is a member of family III of the solute binding proteins. It is 89% identical to the collagen binding protein, Cnb, from Lactobacillus reuteri. Compared with the database of Escherichia coli proteins, BspA is most similar to the L-cystine binding protein FliY. To investigate the fu...

materials and methods lactic acid bacteria isolated from spoiled fruits and vegetables and grown in mrs medium were screened against multi-drug-resistant candida albicans, klebsiella pneumoniae, pseudomonas aeruginosa, escherichia coli, and enterococcus fecalis. results fifty-four lactic acid bacteria were isolated from spoiled fruits and vegetables, of which 11 gram-positive and catalase-negat...

We investigated the probiotic potential of lactic acid bacteria (LAB) obtained from cocoa fermentation using an experimental rat model of colitis. Cocoa beans were collected from fermentation boxes every 12 h for 5 days to isolate the microorganisms. Strains were isolated by serial dilution and plating on MRS agar. Gram-positive and catalase-negative rods were subjected to DNA extraction, polym...

This study aims to screen the antibacterial activity of lactic acid bacteria (LAB) isolated from home-made fermented vegetables against common food borne pathogens. The antagonistic properties of these isolates against Escherichia coli, Staphylococcus aureus, Yersinia enterocolitica and Bacillus cereus were examined using agar well diffusion method. Four LAB namely MF6, MF10, MF13, and MF15 ide...

The lactic acid bacterial (LAB) community dynamics of two wheat and two spelt sourdough fermentations that were daily back-slopped were monitored during a period of 10 days by hybridizing time-related RNA samples, representing the metatranscriptome, to an LAB functional gene microarray. To indicate the species present in each hybridized sample, annotation information for the 2,269 oligonucleoti...

Urogenital infections afflict an estimated one billion people each year. The size of this problem and the increased prevalence of multi-drug resistant pathogens make it imperative that alternative remedies be found. A randomized, placebo-controlled trial of 64 healthy women given daily oral capsules of Lactobacillus rhamnosus GR-1 and Lactobacillus fermentum RC-14 for 60 days showed no adverse ...

Examination of the culture fluids from a number of strains of oral streptococci and latobacilli has shown the presence of an erythrocyte-sensitizing antigen with the properties of lipoteichoic acid. The antigen was isolated from the culture fluids of Lactobacillus casei and Lactobacillus fermentum and characterized chemically and serologically, For other strains, serological evidence for the pr...
