A concept of mould spoilage prevention and acrylamide reduction in wheat bread: application of lactobacilli in combination with a cranberry coating

2018

In this study, a concept for wheat bread moulding prevention and acrylamide reduction has been developed. It includes various lactic acid bacteria (LAB), selected according to their technological, antifungal and acrylamide-lowering properties, in combination with an antifungal cranberry coating for wheat bread surface treatment. All the tested strains (Pediococcus pentosaceus LUHS183, Pediococcus acidilactici LUHS29, Lactobacillus paracasei LUHS244, Lactobacillus brevis LUHS173, Lactobacillus plantarum LUHS135 and Leuconostoc mesenteroides LUHS242) showed antifungal activities against Aspergillus nidulans, Penicillium funiculosum and Fusarium poae. However, L. brevis LUHS173 and Leu. mesent…

Monitoring of wheat lactic acid bacteria from the field until the first step of dough fermentation.

2017

The present work was carried out to retrieve the origin of lactic acid bacteria (LAB) in sourdough. To this purpose, wheat LAB were monitored from ear harvest until the first step of fermentation for sourdough development. The influence of the geographical area and variety on LAB species/strain composition was also determined. The ears of four Triticum durum varieties (Duilio, Iride, Saragolla and Simeto) were collected from several fields located within the Palermo province (Sicily, Italy) and microbiologically investigated. In order to trace the transfer of LAB during the consecutive steps of manipulation, ears were transformed aseptically and, after threshing, milling and fermentation, s…

Neanderthal behaviour, diet, and disease inferred from ancient DNA in dental calculus

VAMP2 encodes the vesicular SNARE protein VAMP2 (also called synaptobrevin-2). Together with its partners syntaxin-1A and synaptosomal-associated protein 25 (SNAP25), VAMP2 mediates fusion of synaptic vesicles to release neurotransmitters. VAMP2 is essential for vesicular exocytosis and activity-dependent neurotransmitter release. Here, we report five heterozygous de novo mutations in VAMP2 in unrelated individuals presenting with a neurodevelopmental disorder characterized by axial hypotonia (which had been present since birth), intellectual disability, and autistic features. In total, we identified two single-amino-acid deletions and three non-synonymous variants affecting conserved resid…

Molecular Identification of Lactic Acid Bacteria Occurring in Must and Wine

2016

A specifically amplified polymorphic DNA-polymerase chain reaction (SAPD-PCR), a molecular fingerprinting method based on the amplification of specific gene sequences, was applied in order to allow a rapid identification of lactic acid bacteria (LAB) occurring in must and wine. The applicability of this method was confirmed with isolated strains from different wine samples from the German wine growing region Palatinate. In addition, the formation of biogenic amines by the isolated strains was studied. More than half of the bacterial isolates from 50 red and white wine samples were able to produce biogenic amines. General health concerns related to biogenic amines in must and wine underline …

Lactic Acid Bacteria Combinations for Wheat Sourdough Preparation and Their Influence on Wheat Bread Quality and Acrylamide Formation

2017

Different lactic acid bacteria (LAB) from spontaneous wheat sourdough were isolated, identified, and characterized by their growth, acidification rate, and carbohydrate metabolism. The combinations of isolated LAB (Pediococcus pentosaceus LUHS183 and Leuconostoc mesenteroides LUHS242, P. pentosaceus LUHS183 and Lactobacillus brevis LUHS173, P. pentosaceus LUHS183 and Enterococcus pseudoavium LUHS 234, P. pentosaceus LUHS183 and Lactobacillus curvatus LUHS51, Lactobacillus plantarum LUHS135 and L. curvatus LUHS51, L. plantarum LUHS135 and P. pentosaceus LUHS183) were used for wheat sourdough production, and the effects of LAB fermentation in sourdoughs on wheat bread quality parameters and a…

Biosurfactant production by hydrocarbon-degradingBrevibacteriumandVibrioisolates from the sea penPteroeides spinosum(Ellis, 1764)

2016

Among filter-feeders, pennatulids are the most complex and polymorphic members of the cnidarian class Anthozoa. They display a wide distribution throughout all the oceans, constituting a significant component of the sessile megafauna from intertidal to abyssal depths. In this study, a total of 118 bacterial isolates from enrichment cultures, carried out with homogenates of the sea pen Pteroeides spinosum (Ellis, 1764), were screened for hydrocarbon utilization by using the 2,6-dichlorophenol indophenol assay. Among them, 83 hydrocarbon-oxidizing isolates were analyzed for biosurfactant production by standard screening tests (i.e., emulsifying activity, E24 detection, surface tension measure…

Assimilation of problematic experiences in Brief Strategic Therapy: Olivia and her fear of dying /La asimilación de experiencias problemáticas en la …

2016

AbstractIn this research process, Stiles’ assimilation of problematic experiences scale is used to study Olivia’s process of change. The objectives of this study are: first, to describe Olivia’s therapeutically successful assimilation of the problematic experience of fear of dying, treated with brief strategic therapy; and second, to study how that pattern of assimilation unfolded. We can conclude that Olivia assimilated her problematic experience of fear of dying by following a fluctuating and irregular pattern.

Safety and immunomodulatory effects of three probiotic strains isolated from the feces of breast-fed infants in healthy adults: SETOPROB study.

2013

We previously described the isolation and characterization of three probiotic strains from the feces of exclusively breast-fed newborn infants: Lactobacillus paracasei CNCM I-4034, Bifidobacterium breve CNCM I-4035 and Lactobacillus rhamnosus CNCM I-4036. These strains were shown to adhere to intestinal mucus in vitro, to be sensitive to antibiotics and to resist biliary salts and low pH. In the present study, a multicenter, randomized, double-blind, placebo-controlled trial with 100 healthy volunteers in three Spanish cities was carried out to evaluate the tolerance, safety, gut colonization and immunomodulatory effects of these three probiotics. Volunteers underwent a 15-day washout perio…
