Sourdough fermentation is an ancient technique to ferment cereal flour that improves bread quality, bringing nutritional and health benefits. The fermented dough has a complex microbiome composed mainly of lactic acid bacteria yeasts. During fermentation, the production metabolites chemical reactions occur, giving product unique characteristics high sensory quality. Mastery allows adjustment gl...

The application of sourdough is considered to be a key tool for the production high-quality bread. Several advantages have been presented through in bread making, such as increased shelf life, improved aromatic profiles and sensory characteristics, nutritional value, health benefits. Technological benefits also recorded, successful gluten-free breads. Likewise, an upsurge interest applications ...

acrylamide as a possible carcinogenic compound is known to produce in heated carbohydrate-rich food such as bread. in this study, the effect of the fermentation process by four lactic acid bacteria (lab) and yeaston an industrial scale, was studied on acrylamide reduction in bread. results showed that the flour specifications and the kind of microorganisms in the fermentation process are import...

The Bacillus genus is a heterogeneous group of Gram-positive, facultative anaerobic, endospore-forming bacteria spread into the environment, even though soil is generally accepted as its natural reservoir. The ability to produce endospores allows Bacillus to withstand extreme environmental conditions as those occurring in food processing. Bacillus spp., particularly B. subtilis, are usually fou...

The phytase activity of 12 species of sourdough lactic acid bacteria was screened. It was intracellular only, largely distributed among the species and strains of Lactobacillus sanfranciscensis possessed the highest levels of activity. A monomeric ca. 50-kDa phytase was purified to homogeneity from L. sanfranciscensis CB1 by three chromatographic steps. L. sanfranciscensis CB1 exhibited the hig...

BACKGROUND Epidemiological studies associate consumption of whole grain foods, including breads, with reduced cardiovascular disease (CVD) risk; however, few studies have compared wheat whole grains with wheat refined grains. METHODS This study investigated effects of 6-week consumption of whole grain wheat sourdough bread in comparison to white bread on fasting serum lipids in normoglycemic/...

A variety of foods have been implicated in symptoms of patients with Irritable Bowel Syndrome (IBS) but wheat products are most frequently cited by patients as a trigger. Our aim was to investigate the effects of breads, which were fermented for different lengths of time, on the colonic microbiota using in vitro batch culture experiments. A set of in vitro anaerobic culture systems were run ove...

Kazachstania saulgeensis is a recently described species isolated from French organic sourdough. Here, we report the high quality genome sequence of a monosporic segregant of the type strain of this species, CLIB 1764T (= CBS 14374T). The genome has a total length of 12.9 Mb and contains 5326 putative protein-coding genes, excluding pseudogenes and transposons. The nucleotide sequences were dep...
