Persistence of a mixed lactic acid bacterial starter culture during lysine fortification of sourdough breads by addition of pistachio powder
2020
Abstract Pistachio powder was added to flour or semolina to evaluate its contribution to increase the amount of lysine in bread. Bread production was carried out by sourdough technology using a selected 3-species (Lactobacillus sanfranciscensis/Leuconostoc citreum/Weissella cibaria) lactic acid bacterial (LAB) starter culture. All sourdoughs were subjected to a long-time fermentation (21 h) and showed levels of LAB around 109 CFU/g, indicating the suitability of pistachio powder for lactic fermentation. Yeasts were also detected, in particular in semolina trials. MiSeq Illumina technology was applied to investigate the bacterial composition of sourdoughs evidencing a different distribution …
Function and evolution of vertebrate globins.
2014
Globins are haem-proteins that bind O2 and thus play an important role in the animal's respiration and oxidative energy production. However, globins may also have other functions such as the decomposition or production of NO, the detoxification of reactive oxygen species or intracellular signalling. In addition to the well-investigated haemoglobins and myoglobins, genome sequence analyses have led to the identification of six further globin types in vertebrates: androglobin, cytoglobin, globin E, globin X, globin Y and neuroglobin. Here, we review the present state of knowledge on the functions, the taxonomic distribution and evolution of vertebrate globins, drawing conclusions about the fu…
Effect of a physical pre-treatment and drying on carotenoids of goji berries ( Lycium barbarum L.)
2018
In order to evaluate the influence of an abrasive pre-treatment and drying at 50 °C, 60 °C, 70 °C of goji fruits (Lycium barbarum L.), changes in colour and carotenoids were studied. An extraction method was modified and adapted to assay the main carotenoid esters and saponified carotenoids of goji berries, before and after treatments. Goji berries were confirmed as a high source of zeaxanthin, with zeaxanthin-dipalmitate at about 2 g/kg dry weight. The reliability of the analytical method was confirmed by the high quantitative recoveries, about 100%, a higher repeatability than reference methods and a good reproducibility (lower than 5%). After drying, significant but small carotenoid loss…
A Review on "Lyricism and Chinese Modern Poetics" by Zhang Songjian
2015
La recensione mette in luce il nodo focale della ricerca dello studioso cinese Zhang Songjian nella sua analisi sul Modernismo nella poesia cinese degli anni '40. Lo studioso innova l'ambito della ricerca introducendo i concetti di "lyricism", "anti-lyricism" e "deep lyricism" che contribuiscono ad aprire nuove prospettive nel dialogo critico Occidente-Oriente sulla poesia cinese. The review underlines the focus of the research of the Chinese scholar Zhang Songjian in his analysis of Chinese poetry Modernism of the 40s. His innovative research is based on the concepts of "lyricism", "anti-lyricism" and "deep-lyricism" that contribute the opening of new perspectives in the Western-Eastern di…
Differential inclusions involving normal cones of nonregular sets in Hilbert spaces
2017
This thesis is dedicated to the study of differential inclusions involving normal cones of nonregular sets in Hilbert spaces. In particular, we are interested in the sweeping process and its variants. The sweeping process is a constrained differential inclusion involving normal cones which appears naturally in several applications such as elastoplasticity, electrical circuits, hysteresis, crowd motion, etc.This work is divided conceptually in three parts: Study of positively alpha-far sets, existence results for differential inclusions involving normal cones and characterizations of Lyapunov pairs for the sweeping process. In the first part (Chapter 2), we investigate the class of positivel…
The presence of conifer resin decreases the use of the immune system in wood ants.
2008
5 pages; International audience; 1. Wood ants ( Formica paralugubris ) incorporate large amounts of solidified conifer resin into their nest, which reduces the density of many bacteria and fungi and protects the ants against some detrimental micro-organisms. By inducing an environment unfavourable to pathogens, the presence of resin may allow workers to reduce the use of their immune system. 2. The present study tested the hypothesis that the presence of resin decreases the immune activity of wood ants. Specifically, three components of the humoral immune defences of workers kept in resin-rich and resin-free experimental nests (antibacterial, lytic, and prophenoloxidase activities) were com…
Acyl-homoserine lactone production is more common among plant-associated Pseudomonas spp. than among soilborne Pseudomonas spp.
2001
ABSTRACT A total of 137 soilborne and plant-associated bacterial strains belonging to different Pseudomonas species were tested for their ability to synthesize N -acyl-homoserine lactones (NAHL). Fifty-four strains synthesized NAHL. Interestingly, NAHL production appears to be more common among plant-associated than among soilborne Pseudomonas spp. Indeed, 40% of the analyzed Pseudomonas syringae strains produced NAHL which were identified most often as the short-chain NAHL, N -hexanoyl- l -homoserine lactone, N -(3-oxo-hexanoyl)-homoserine lactone, and N -(3-oxo-octanoyl)- l -homoserine lactone (no absolute correlation between genomospecies of P. syringae and their ability to produce NAHL …

City gates of Augustodunum and their architectural models (Gaul, Italy, Western Provinces of the Roman Empire)
2013
Augustodunum, civitas Aeduorum, roman city founded under the reign of Augustus, was equipped with four roman city gates : the gate of Arroux and the gate of Saint André, both well preserved, the gate of Saint Andoche which sole remaining part is a flanking tower, and the gate of Rome, destroyed long ago.The heart of this study lies in the stratigraphic reading of those gates structure and in thoughts about the building site of Autun’s city gates operating process. Moreover, since the 16th century, antiquaries, travelers and artists have described in many ways their visits to the roman city gates of Autun. These accounts constitute a major documentary collection of written and iconographical…
Leaching of diuron and oryzalin in undisturbed lysimeters of three vineyard soils (Vosne-Romanée, 21)
2001
La mobilité du diuron et de l'oryzalin a été étudiée en colonnes de sol non perturbé au laboratoire. Les sols étudiés sont trois sols viticoles de la région Bourgogne (Vosne-Romanée, 21) et ont été prélevés selon une topolithoséquence. Leurs teneurs en carbone organique sont respectivement de 1,2 %, 1,7 % et 2,2 % pour le sol brun calcaire de mi-pente (SBC MP), le sol brun calcaire de bas de pente (SBC BP) et la rendzine. Après une hauteur de pluie simulée de 845 mm, les percolats respectifs de la rendzine, du SBC MP et du SBC BP contiennent des quantités plus importantes de diuron (3,2 %, 11,8 % et 18,8 %), que d'oryzalin (0,2 %, 4,9 % et 3,7 % des quantités appliquées). Dans les colonnes …
