PAESAGGI IN TRASFORMAZIONE: LA RIGENERAZIONE DEL BACINO MINERARIO DEL NORD PAS DE CALAIS L’iscrizione Unesco e la costruzione della strategia generale

2017

L’attività mineraria, al pari di un evento sismico, rappresenta per il territorio una ferita difficile da rimarginare. I luoghi coinvolti assistono al radicale mutamento dei loro paesaggi, alla trasformazione della loro geografia, alla rottura degli equilibri che per secoli avevano sostenuto la loro economia e società. Questa condizione si aggrava ancor di più a seguito della dismissione delle attività, quando il sistema economico della monocoltura mineraria non costituisce più una risorsa e al suolo rimangono i segni di ciò che era stata l’industria estrattiva. I resti fisici dell’attività industriale iniziano, però, dopo alcuni anni, a esercitare un senso di fascinazione sulla stessa soci…

Les souches d'E. coli résistantes aux antibiotiques

2016

National audience; Le projet "CIREC" vise à étudier la prévalence et la caractérisation des souches d’E.coli productrices de β-lactamase à spectre élargi (BLSE) de type CTX-M dans les eaux usées et les boues issues d’une quarantaine de stations d’épuration (STEP) de la région Bourgogne. Puis, il s’agira d’identifier et caractériser les voies possibles de transfert de ces souches, les rejets d’effluents traités des STEP dans les rivières pouvant avoir des conséquences sur la contamination de la faune aquatique d’eau douce.

Critical reading of some papers related to the Bibracte basin

2021

Since its discovery in 1987, the monumental basin of Bibracte questions archeologists because of its atypical orientation that was thought not to follow the way on which it lies. We study 4 archeoastronomical papers dealing with the orientation of the short and long axes on the sun rise at winter solstice or on peculiar stars and we discuss the validity of these hypotheses.

Les espaces funéraires laténien et augusto-tibérien des Reliades (Le Puy-en-Velay, Haute-Loire).

2022

Le site des Reliades au Puy-en-Velay (Haute-Loire) a livré deux petits espaces funéraires à crémation utilisés entre La Tène finale et l’époque augusto-tibérienne. Caractérisés par une implantation sur un lieu à la topographie remarquable, ils ont fait l’objet d’aménagements paysagers qui viennent souligner leur caractère ostentatoire. Par ailleurs, la présence de bassins pose la question de l’utilisation de l’eau dans le cadre de cérémonies funéraires et/ou commémoratives. Enfin, bien que le mobilier déposé dans les sépultures soit peu abondant et très détérioré par son passage sur le bûcher, quelques éléments permettent d’attribuer aux défunts un statut social relativement élevé. Il s’agi…

Pyrosequencing survey of intestinal microbiota diversity in cultured sea bass (Dicentrarchus labrax) fed functional diets.

2014

The routine use of chemotherapy to control bacterial diseases in aquatic populations has resulted in the development and spread of antibiotic resistance. The inclusion of immunostimulants in fish diets (functional diets) is one of the main strategies to solve this threat. This study aimed to analyse the intestinal microbiota of cultured European sea bass (Dicentrarchus labrax) fed two functional diets applying pyrosequencing of PCR-amplified 16S rRNA gene. Quality-filtered reads were assigned to family and genus taxonomic levels using the Ribosomal Database Project classifier. The autochthonous intestinal microbiota of sea bass consisted of two dominant bacterial genera: Dysgonomonas (Bacte…

Near infrared reflectance spectroscopy (NIRS) characterization of European sea bass (Dicentrarchus labrax) from different rearing systems

2009

The present study aimed to predict by NIRS the proximate chemical composition and some carcass traits of sea bass coming from 11 farms with different rearing systems (extensive, intensive in land-based basins, sea cages) and located in northern (Friuli, Veneto), central (Tuscany) and southern (Puglia and Sicily) Italy. NIRS analysis of freeze dried sea bass fillets gave fairly good predictions of slaughter weight and fillet yield (R2cv=0.48-0.55), while results for carcass yield were poor. NIRS analysis was highly predictive for the condition factor (R2cv=0.790, SECV=0.09) and for water, ether extract and gross energy showing high correlations (R2cv>0.90) with NIR spectral infor- mation and…

Real-time RT-PCR detection of betanodavirus in naturally and experimentally infected fish from Spain

2011

Infections with betanodavirus affect a wide range of wild and farmed fish species throughout the world, mostly from the marine environment. The aim of this work was to develop and validate real-time RT-PCR assays for sensitive and specific detection of nodavirus in diseased or carrier fish. The new detection assay was used to study the transmission and development of nodavirus infection in juvenile sea bass, Dicentrarchus labrax (L.), challenged by different routes, and also to screen for nodavirus in various farmed fish species. On average, the sensitivity was 10-100 times higher than a standard RT-PCR, and the assay was able to detect asymptomatic carrier fish that otherwise could have be…

Probiotic properties of Brevibacillus brevis and its influence on sea bass (Dicentrarchus labrax) larval rearing

2012

Efficacy of Brevibacillus brevis strain and its influence on larval rearing of sea bass (Dicentrarchus labrax) were investigated in the present work. Biochemical analyses permit to identify this strain as B. brevis. This bacterium has an inhibitory effect against fish pathogenic bacteria, especially the genus of Vibrio. Enzymatic characterization revealed that B. brevis was lipase positive, amylase, lecithinase and caseinase negative. Adherence assays to abiotic surfaces and challenge test with Artemia larvae demonstrate that B. brevis was fairly adherent and play an important role in the enhancement of the protection of Artemia culture against pathogens. Treatment of sea bass larvae with B…
