Factors affecting the production of putrescine from agmatine by Lactobacillus hilgardii X1B isolated from wine
2008
Aims: To elucidate and characterize the metabolic putrescine synthesis pathway from agmatine by Lactobacillus hilgardii X1B. Methods and Results: The putrescine formation from agmatine by resting cells (the normal physiological state in wine) of lactic acid bacteria isolated from wine has been determined for the first time. Agmatine deiminase and N-carbamoylputrescine hydrolase enzymes, determined by HPLC and LC-Ion Trap Mass Spectrometry, carried out the putrescine synthesis from agmatine. The influence of pH, temperature, organic acids, amino acids, sugars and ethanol on the putrescine formation in wine was determined. Conclusions: Resting cells of Lact. hilgardii X 1B produce putrescine …
Regulation of hdc expression and HDC activity by enological factors in lactic acid bacteria.
2008
Aims: The aim of this work was to study the influence of enological factors on the histidine decarboxylase gene (hdc) expression and on histidine decarboxylase enzyme (HDC) activity in Lactobacillus hilgardii, Pediococcus parvulus and Oenococcus oeni. Methods and Results: Cell extracts and whole cells were used. Glucose, fructose, malic acid and citric acid diminished the hdc expression. Ethanol did not increase hdc expression or activity in cells, but increased HDC activity. Temperature and pH had effect on the activity of HDC but not on hdc expression. Tartaric acid and l-lactic acid, and sulphur dioxide (SO2) had no effect on enzyme synthesis and activity. Bacterial species differ in t…

Effectiveness of a kindergarten-based intervention to increase vegetable intake and reduce food neophobia amongst 1-year-old children: a cluster rand…
2021
Background: Children’s first years of life are crucial to their future health. Studies show that a varied diet with a high intake of vegetables is positive in several domains of health. The present low vegetable intake amongst children is, therefore, a concern. Food neophobia is a common barrier to vegetable intake in children. As most Norwegian children attend kindergarten from an early age, kindergartens could contribute to the prevention of food neophobia and the promotion of vegetable intake. Objective: The aim of this study was to assess the effect of a cluster randomised trial amongst 1-year-old children in kindergarten to reduce food neophobia and promote healthy eating. Methods: Kin…
From soil to soil-less in horticulture: quality and typicity
2013
In this review, the technique of soil-less cultivation of horticultural crops is analysed, the main differences between this and traditional cultivation techniques are described, and the advantages and disadvantages of each method in relation to the others are identified. Soilless cultivation has revolutionised various sectors of vegetable and floriculture production, and recent years have also seen interest being shown by Italian fruit crop producers, particularly those involved in table grape viticulture. The various issues related to the use of this technique are described in relation to the needs of the substrate, water management, and mineral nutrition of the different species, and to …

What I say is not necessary what I do: pulses consumption in French adults
2018
International audience; The consumption of pulses in the human diet is considered to have several advantages: from a nutritional point of view, pulses are rich in dietary fibers, complex carbohydrate, minerals/vitamins and an important source of vegetal proteins. They are considered essential to insure food security and support environmental sustainability. Despite these benefits, the consumption of pulses in France has declined over the past decades, dropping from 7.2 kg in 1920 to 1.7 kg/ person per year in 2016. The aim of this study is to understand the representation of pulses among French non-vegetarian consumers, using a direct method (questionnaire) and an indirect method (scenario …

« Deirdre O’Mahony, artiste et archéologue des savoirs techniques indigènes »
2022
Les projets participatifs et collaboratifs de l’artiste irlandaise Deirdre O’Mahony, ancrés dans le monde rural du Burren, valorisent le patrimoine vernaculaire et les savoir-faire indigènes. Ses recherches de terrain portant sur l’évolution du paysage abordé comme milieu et les collaborations multiples qu’elle entreprend aboutissent à des propositions artistiques revisitant le land art. Ses interventions dans le paysage sont souvent complétées par des propositions dialogiques, dont le repas partagé, qui invite les participants à explorer l’histoire des lieux, les jeux de pouvoir qui s’y tissent et la pertinence des savoirs vernaculaires pour les enjeux de demain, notamment en matière de sé…
Advances in Wine Fermentation
2021
Fermentation is a well-known natural process that has been used by humanity for thousands of years, with the fundamental purpose of making alcoholic beverages such as wine, and also other non-alcoholic products. From a strictly biochemical point of view, fermentation is a process of central metabolism in which an organism converts a carbohydrate, such as starch or sugar, into an alcohol or an acid. The fermentation process turns grape juice (must) into wine. This is a complex chemical reaction whereby the yeast interacts with the sugars (glucose and fructose) in the must to create ethanol and carbon dioxide. Fermentation processes to produce wines are traditionally carried out with Saccharo…
