Formulation, process conditions, and biological evaluation of dairy mixed gels containing fava bean and milk proteins: Effect on protein retention in…
2019
International audience; Food formulation and process conditions can indirectly influence AA digestibility and bioavailability. Here we investigated the effects of formulation and process conditions used in the manufacture of novel blended dairy gels (called "mixed gels" here) containing fava bean (Vicia faba) globular proteins on both protein composition and metabolism when given to young rats. Three mixed dairy gels containing casein micelles and fava bean proteins were produced either by chemical acidification (A) with glucono-δ-lactone (GDL) or by lactic acid fermentation. Fermented gels containing casein and fava bean proteins were produced without (F) or with (FW) whey proteins. The AA…

Symbiotic N2 fixation activity in relation to C economy of Pisum sativum L. as a function of plant phenology
2003
The relationships between symbiotic nitrogen fixation (SNF) activity and C fluxes were investigated in pea plants (Pisum sativum L. cv. Baccara) using simultaneous 13 C and 15 N labelling. Analysis of the dynamics of labelled CO 2 efflux from the nodulated roots allowed the different components associated with SNF activity to be calculated, together with root and nodule synthetic and maintenance processes. The carbon costs for the synthesis of roots and nodules were similar and decreased with time. Carbon lost by turnover, associated with maintenance processes, decreased with time for nodules while it increased in the roots. Nodule turnover remained higher than root turnover until flowering…
Rhizobium leguminosarum imobilizācija uz organiskiem un neorganiskiem substrātiem
2015
Rhizobium leguminosarum ir slāpekli fiksējošas baktērijas, kas spēj veidot gumiņus uz tauriņziežu saknēm. Ar imobilizētu rizobiju preparātiem iespējams inokulēt baktērijas augsnē un uzlabot tauriņziežu augu produktivitāti. Izmantojot rizobiju inokulantus, iespējams aizvietot slāpekļa minerālmēslojumu. Pētīta substrāta un temperatūras ietekme uz imobilizētu R. leguminosarum dzīvotspēju, ilgstoši glabājot. Apskatīti 5 dažādi substrāti, baktēriju suspensija sterilā ūdenī un 4 dažādas glabāšanas temperatūras. Konstatēts, ka R. leguminosarum dzīvotspēju ietekmē gan substrāts, uz kura tās imobilizētas, gan glabāšanas temperatūra. Ilgstošai baktēriju dzīvotspējas saglabāšanai ieteicams kā substrāt…
Influence of arbuscular mycorrhizal colonisation on cadmium induced Medicago truncatula root isoflavonoid accumulation.
2012
Cadmium is a serious environmental pollution threats to the planet. Its accumulation in plants affects many cellular functions, resulting in growth and development inhibition, whose mechanisms are not fully understood. However, some fungi forming arbuscular mycorrhizal symbiosis with the majority of plant species have the capacity to buffer the deleterious effect of this heavy metal. In the present work we investigated the capacity of Rhizophagus irregularis (syn. Glomus irregularis) to alleviate cadmium stress in Medicago truncatula. In spite of a reduction in all mycorrhizal parameters, plants colonized for 21 days by R. irregularis and treated by 2 mg kg(-1) cadmium displayed less growth…
Bradyrhizobium sp. nodulating the Mediterranean shrub Spanish broom (Spartium junceum L.)
2002
Aims: The molecular diversity of 25 strains of rhizobia, isolated in Sicily from root nodules of the Mediterranean shrubby legume Spanish broom (Spartium junceum L.), is presented in relation to the known rhizobial reference strains. Methods and Results: Our approach to the study of the S. junceum rhizobial diversity combined the information given by the 16S and the intergenic spacer (IGS) 16S–23S rDNA polymorphic region by obtaining them in a single polymerase chain reaction (PCR) step. The PCR fragment size of the S. junceum isolates was 2400–2500 bp and that of the reference strains varied from 2400 in Bradyrhizobium strains to 2800 in Sinorhizobium strains. Inter- and intrageneric lengt…
Plant phenology and genetic variability in root and nodule development strongly influence genetic structuring of Rhizobium leguminosarum biovar vicia…

Publication Inra prise en compte dans l'analyse bibliométrique des publications scientifiques mondiales sur les Fruits, les Légumes et la Pomme de terre. Période 2000-2012. http://prodinra.inra.fr/record/256699; International audience; The symbiotic relationships between legumes and their nitrogen (N-2)-fixing bacterial partners (rhizobia) vary in effectiveness to promote plant growth according to both bacterial and legume genotype. To assess the selective effect of host plant on its microsymbionts, the influence of the pea (Pisum sativum) genotype on the relative nodulation success of Rhizobium leguminosarum biovar viciae (Rlv) genotypes from the soil populations during plant development h…
Importance de la variabilité génétique bactérienne sur le fonctionnement de la symbiose Rhizobium leguminosarum biovar viciae avec le pois (Pisum sat…
2008
Les irrégularités de rendement et de teneur en protéine des graines que présente la culture du pois sont, en partie, liées à des problèmes de nutrition azotée. En tant que légumineuse, la nutrition azotée du pois repose à la fois sur la fixation symbiotique de l’azote atmosphérique et sur l’absorption racinaire des nitrates du sol. Notre principal objectif a été de déterminer si le partenaire bactérien, Rhizobium leguminosarum biovar viciae (Rlv), peut être un facteur limitant de la nutrition azotée et du rendement du pois. La variabilité génétique des Rlv et les facteurs influençant la structure des populations de Rlv à l'état libre et symbiotiques ont été étudiés. La signification de la d…
Impiego di granelle di leguminose in alternativa alla soia nella produzione di carne ovina biologica
2009
Use of legume grains in substitution of soybean meal in organic lamb meat production. This study aimed to evaluate the effects of replacing soybean meal in the diet with alternative legume grains without GMO presence and at low aflatoxin risk, on the growth and carcass and meat quality traits of lambs. After weaning at 66±6 d of age, 28 male Comisana lambs were divided into 4 groups and gradually adapted to diets over a 15-d period. Until slaughter at 129±6 d of age, each group received ad libitum pelleted alfalfa hay and concentrates differing for the protein source: chickpeas (CP), faba beans (FB), peas (PE) and soybean meal (SM). Lambs growth and carcasses weight were not modified by the…
