An innovative method to produce green table olives based on "pied de cuve" technology
2015
The technology of “pied de cuve” (PdC) is applied in food process only to produce wines with an enriched community of pro-technological yeasts. PdC promotes the growth of the desirable microbial strains in a small volume of grape must acting as a starter inoculums for higher volumes. The aim of the present work was to investigate the use of partially fermented brines, a technology known as PdC, developed with lactic acid bacteria (LAB) on the microbiological, chemical and sensory characteristics of green fermented table olives during two consecutive campaigns. The experimental plan included two trials based on different PdCs: trial A, PdC obtained with Lactobacillus pentosus OM13; trial B, …
The coffee-machine bacteriome: biodiversity and colonisation of the wasted coffee tray leach
2015
AbstractMicrobial communities are ubiquitous in both natural and artificial environments. However, microbial diversity is usually reduced under strong selection pressures, such as those present in habitats rich in recalcitrant or toxic compounds displaying antimicrobial properties. Caffeine is a natural alkaloid present in coffee, tea and soft drinks with well-known antibacterial properties. Here we present the first systematic analysis of coffee machine-associated bacteria. We sampled the coffee waste reservoir of ten different Nespresso machines and conducted a dynamic monitoring of the colonization process in a new machine. Our results reveal the existence of a varied bacterial community…
Modelling the effect of ascorbic acid, sodium metabisulphite and sodium chloride on the kinetic responses of lactic acid bacteria and yeasts in table…

he goal of this work was to apply the Quasi-chemical primary model (a system of four ordinary differential equations that derives from a hypothetical four-step chemical mechanism involving an antagonistic metabolite) in the study of the evolution of yeast and lactic acid bacteria populations during the storage of Manzanilla–Aloreña table olives subjected to different mixtures of ascorbic acid, sodium metabisulphite and NaCl. Firstly, the Quasi-chemical model was applied to microbial count data to estimate the growth–decay biological parameters. The model accurately described the evolution of both populations during storage, providing detailed information on the microbial behaviour. Secondly…

Hooligans, Ultras and Vandals
2015
Football hooliganism in its modern sense is often said to have started in Great Britain in 1961, after a serious riot broke out during a match between Tottenham Hotspur and Sunderland; although crowd disorder was not unknown in other countries, this event is regarded as the birth date of the so-called ‘English disease’, which grew in seriousness and extent over the next few decades. The increasing professionalization and internationalization of English football during the 1950s generated a need for greater profits in football clubs that brought about a reorganization of stadiums (Taylor, 1971). Due to this reorganization, young working-class people were relocated at the ends of the stadiums…

Geography of Emotions Across the Black Mediterranean: Oral Memories and Dissonant Heritages of Slavery and the Colonial Past
2019
AbstractThis contribution is dedicated to analysing oral memories about the Black Mediterranean through interviews with people from or culturally linked to the Horn of Africa. The aim is to consider how the interviewees make use of archives to voice their feelings about the past and present in Africa and Europe. I introduce the concept of a “geography of emotions” as a set of different perceptions of Europe and its past. The mobilization of these memories in new interpretative perspectives is part of a dissonant heritage which is actively working inside the European borders in order to produce new cultural identities, to reiterate forms of belonging to black diasporic communities, and to in…
Dynamics of fungal colonization in a new medical mycology laboratory
2012
International audience; Objective of the study. - Study of the spatio-temporal fungal colonization in a new medical mycology laboratory. Methods. - A 17-month survey of airborne fungal contamination was conducted in a new medical mycology laboratory at a tertiary care university hospital. This survey was implemented at three different periods: before the new premises were occupied (period A), during the move into the new laboratory (period B) and after resumption of the mycological activities in these new premises (period C). Results. - During period A, the airborne fungal load ranged from 2.3 to 6 cfu/m(3). The most frequently recovered airborne fungi were Penicillium spp. (75 to 100%). Du…
Effect of inoculum size and water activity on the time to visible growth of Penicillium chrysogenum colony.
2012
In order to assess the effect of the inoculum size on the time to visible growth for Penicillium chrysogenum, the correlation described by Gonzalez et al. (Gonzalez, H.H.L., Resnik, S.L., Vaamonde, G., 1987. Influence of inoculum size on growth rate and lag phase of fungi isolate from Argentine corn. International Journal of Food Microbiology 4, 111-117) was compared to the model introduced by Gougouli et al. (Gougouli, M., Kalantzi, K., Beletsiotis, E., Koutsoumanis, K.P., 2011. Development and application of predictive models for fungal growth as tools to improve quality control in yogurt production. Food Microbiology 28, 1453-1462). Based on the regression coefficient, the latter model p…
