Emerging opportunities for the effective valorization of wastes and by-products generated during olive oil production process: Non-conventional metho…

2015

Abstract Background A large amount of wastes and by-products are generated during olive oil production process. Traditionally, these products have been considered as a problem. However, they constitute a great source of high-added value compounds, which have the potential to be used as food additives and/or nutraceuticals. Therefore, valorization of wastes and by-products from food industry kills two birds with one stone and addresses both the use of waste and by-products and societal health, thus greatly contributing for a sustainable food chain from an environmental and economical point of view. Scope and approach In the present review, current and new insights in the recovery of high-add…

Pretreatment of trace element-enriched biomasses grown on phytomanaged soils for bioethanol production

2017

Abstract Phytotechnologies are a set of sustainable, ecological options notably for alleviating pollutant linkages induced by contaminated soils. However, concerns exist regarding the processing of trace elements (TE)-enriched biomass and the fate of TEs in the end-products. The fractionation of phytoremediation TE-enriched non-woody lignocellulosic (tobacco) and woody (birch, willow) phytoremediation-borne biomasses was studied using ethanol organosolv, soda and dilute acid pretreatments. TE distribution in the process fractions (pulp, liquid effluents and lignin) was further examined. In dilute acid conditions, a wood pretreatment performed at 170 °C in the presence of 2% w/w of sulfuric …

Biogeographical patterns of soil bacterial communities.

2009

International audience; This study provides the first maps of variations in bacterial community structure on a broad scale based on genotyping of DNA extracts from 593 soils from four different regions of France (North, Brittany, South-East and Landes). Soils were obtained from the soil library of RMQS (Réseau de Mesures de la Qualité des Sols = French soil quality monitoring network). The relevance of a biogeographic approach for studying bacterial communities was demonstrated by the great variability in community structure and specific geographical patterns within and between the four regions. The data indicated that the distribution of bacterial community composition might be more relate…

Highlighting the role of diversity in driving weed dynamics and weed-crop interactions

2017

SPEBIOME INRA; Le Microscope à Dissection Laser (MDL) est composé de l’association d’un microscope équipé d’objectifs permettant un grossissement x2 à x100 et d’un système optique de découpe laser. Il permet de microdisséquer de façon ciblée des échantillons biologiques, de type bactérien, animal ou végétal. Sa finesse de dissection permet de sélectionner, d’isoler puis de récupérer des cellules cibles afin de concentrer le matériel. Ainsi, il est possible de réaliser des analyses de transcriptomique, de génomique ou de protéomique à partir de cellules cibles. Avant de microdisséquer, la préparation des échantillons est primordiale pour s’assurer de récupérer une qualité et une quantité suf…

Biogeographical patterns of soil molecular microbial biomass

2011

Affiche - résumé. Session GC: Microbes in the Changing Environmenl: Global Climate Change and Soif under Human Impact; International audience; The spatial organization of soil microbial communities over large areas and the identification of environmental factors structuring their distribution have been liUle investigated. The overall objective of this study was to determine the spatial paUerning of microbial biomass in soils on wide extent and to rank the environmental fiUers most influencing this distribution, by using the French Soil Quality Monitoring Network. This network covers ail the French terrilory and soils were sampled at2,150 sites along a systematic grid sampling. The soil DNA …

Optimisation de la procédure d'extraction d'ADN des sols pour caractériser la diversité microbienne tellurique par le pyroséquençage des gènes riboso…

2013

Depuis plusieurs années, les communautés microbiennes du sol (bactériennes et fongiques) sont étudiées au travers de leur ADN. Le mode d’extraction de l’ADN du sol revêt donc une importance capitale pour décrire la biodiversité microbienne. A ce jour, de nombreuses procédures d’extraction d’ADN (commerciales ou non) des sols sont disponibles et utilisées. Il est cependant difficile de comparer les résultats d’études ayant utilisés différents protocoles d’extraction. L’emploi d’une méthode d’extraction standardisée est donc devenu indispensable pour comparer les résultats de différents laboratoires, comme la norme “ISO-11063: Soil quality – Method to directly extract DNA from soil” développé…

Qualité du Sol - Méthode pour extraire directement l'ADN d'échantillons de sol (Norme française - internationale)

2012

La présente Norme internationale spécifie une méthode pour extraire directement l'ADN d'échantillons de sol en vue d'analyser la structure globale et l'abondance des communautés microbiennes du sol en utilisant des techniques de PCR. Cette méthode est principalement destinée aux sols agricoles et forestiers. Cette méthode peut ne pas être appropriée aux sols riches en matières organiques (par exemple sols de tourbières) ou aux sols très pollués par des polluants organiques ou des métaux lourds. L'extraction directe de l'ADN d'échantillons de sol fournit des informations précieuses sur l'abondance et la structure des communautés microbiennes qui sont des paramètres clés pour estimer la biodi…
