Valorization of dairy waste and by-products through microbial bioprocesses
28 novembre 2021, HE CondorcetArticle scientifiqueWaste is an inherent and unavoidable part of any process which can be attributed to various factors such as process inefficiencies, usability of resources and discarding of not so useful parts of the feedstock. Dairy is a burgeoning industry following the global population growth, resulting in generation of waste such as wastewater (from cleaning, processing, and maintenance), whey and sludge. These ... -
Development and application of a quantitative real-time PCR assay for rapid detection of the multifaceted yeast Kazachstania servazzii in food.
avril 2017, CARAHArticle scientifiqueThe beneficial contributions of Kazachstania servazzii are well-established in various food processes. This yeast also contributes in the spoilage of finished packaged food due to abundant gas production. In particular, an occurrence of K. servazzii was recently positively correlated with the formation of severe package swelling of some prepared fresh pizzas. To circumscribe this concern, a quantitative ... -
Effects of Chemopreventive Natural Compounds on the Accuracy of 8-oxo-7,8-dihydro-2′-deoxyguanosine Translesion Synthesis
08 juillet 2021, HE CondorcetArticle scientifiqueTranslesion synthesis is a DNA damage tolerance mechanism that relies on a series of specialized DNA polymerases able to bypass a lesion on a DNA template strand during replication or post-repair synthesis. Specialized translesion synthesis DNA polymerases pursue replication by inserting a base opposite to this lesion, correctly or incorrectly depending on the lesion nature, involved DNA polymerase(s), ... -
Industrial-scale Malting Barley (Hordeum vulgare L.) Seed Disinfection by Fog of Ozonated Water Application
05 novembre 2015, HE CondorcetCARAHArticle scientifiqueThe aim of this study was to underscore that seed treatment by the fog of ozonated water constitutes a promising alternative tool, in terms of health and environmental gains, regarding traditional ozone treatment. In order to obtain a clear vision of this performance, the technology was implemented on an industrial scale (malting industry). Under an exposition of barley seeds to 9.8 ppm of dissolved ... -
Investigation and development of potato parentage analysis methods using multiplexed SSR fingerprinting
25 décembre 2014, HE CondorcetCARAHArticle scientifiqueParentage assessment in the potato (Solanum tuberosum L.), based on a reliable characterization of DNA varieties, can be a useful tool in validating pedigree information as well as for assigning potential parents to orphan varieties. The approach suggested in this study was to use the genetic profiles obtained on 577 cultivars using a set of 17 polymorphic simple sequence repeats (SSR) markers in ... -
Measurement of translesion synthesis by fluorescent capillary electrophoresis : 7,8-Dihydro-8-oxodeoxyguanosine bypass modulation by natural products
24 mai 2013, HE CondorcetArticle scientifiqueTranslesion synthesis (TLS) relies on a series of specialized DNA polymerases able to insert a base either correctly or incorrectly opposite a lesion on a DNA template strand during replication or post-repair synthesis. To measure the correct or mutagenic outcome of 7,8-dihydro-8-oxodeoxyguanosine (8-oxodG) bypass by TLS DNA polymerases, a capillary electrophoresis (CE) method with fluorescent label ... -
Use of self-organizing map to analyze images of fungi colonies grown from Triticum aestivum seeds disinfected by ozone treatment
16 octobre 2012, HE CondorcetCARAHArticle scientifiqueWe submitted to ozone treatment Triticum aestivum (common wheat) seeds severely contaminated by fungi. Fungi colonies developed when seeds were placed over malt agar medium in Petri dishes; Fusarium sp. and Alternaria sp. were identified. However, conventional colonies counting did not allow a clear assessment of the effect of ozone disinfection. We thus used self-organizing maps (SOMs) to perform ... -
Morphological variability within the indigenous sheep population of Benin
19 octobre 2021, HE CondorcetArticle scientifiqueKnowledge of both the genetic diversity and geographical distribution of animal genetic resources is a prerequisite for their sustainable utilization, improvement and conservation. The present study was undertaken to explore the current morphological variability within the sheep population in Benin as a prelude for their molecular characterization. From November 2018 to February 2020, 25 quantitative ... -
Construction of a Novel Chimeric Dextransucrase Fused to the Carbohydrate-Binding Module CBM2a
28 septembre 2021, HE CondorcetArticle scientifiqueLactic acid bacteria (LAB) have the potential to produce homoexopolysaccharides (HoPS). Their health benefits and physicochemical properties have been the subject of extensive research. The HoPS functional properties are determined by molecular weight, the type of glycosidic link ages, degrees of branching and chemical composition. The dextransucrases (DSases) produce a kind of HoPS (dextrans), ... -
Biodiversity of Fusarium species in ears and stalks of maize plants in Belgium
21 avril 2011, CARAHArticle scientifiqueIn order to investigate the pre-harvest contamination of maize plants by Fusarium species in Belgium, a three-year survey has been performed in five fields in which three hybrids differing in susceptibility to maize stalk rot were sampled at four different physiological stages. An extensive collection of 5,659 Fusarium isolates characterized at the species level was established during the 2005, 2006, ... -
Effets des différentes balances hormonales sur la micropropagation du Cv. Hybride FHIA-01 (Musa sp.)
juillet 2013, HE CondorcetCARAHArticle scientifiqueDifférentes balances hormonales ont été évaluées afin de proposer un milieu de prolifération permettant de multiplier efficacement l’hybride FHIA-01 en culture in vitro. Les principaux résultats obtenus sont: l’inhibition presque complète de la prolifération par la BAP; l’inhibition totale de l’enracinement par la concentration de 10 µM BAP+10 µM MemTR, l’amélioration de la prolifération moyenne de ... -
Acclimatation de vitroplants de bananier (Musa sp.) en culture hydroponique : impact de différentes concentrations en cuivre sur la croissance des vitroplants
janvier 2013, HE CondorcetCARAHArticle scientifiqueLes contraintes dues au cuivre et les conséquences de son accumulation par les vitroplants de bananier pendant la phase d’acclimatation ont été étudiées en culture hydroponique. Des doses de 0-100-500-1000 ppm de cuivre, sous forme de CuSO4, ont été ajoutées au milieu nutritif en culture hydroponique. A 1000 ppm CuSO4, les résultats obtenus ont mis en évidence des concentrations en cuivre élevées ... -

Exploiting Genetic Variability of Root Morphology as a Lever to Improve Nitrogen Use Efficiency in Oilseed Rape
29 juillet 2018, HE CondorcetCARAHLivre/Ouvrage ou monographieNitrogen (N) is the quantitatively most important nutrient in cropping systems. The use of nitrate as a mineral fertilizer is highly energy-intensive and causes greenhouse gas emission and groundwater pollution. Therefore, the need to reduce N-fertilizer input is pressing. In order to compensate that reduction, new crop genotypes must be sought with improved nitrogen use efficiency (NUE). While ... -
Root Morphological Traits of Seedlings Are Predictors of Seed Yield and Quality in Winter Oilseed Rape Hybrid Cultivars
15 octobre 2020, HE CondorcetCARAHArticle scientifiqueThe root system is responsible for soil resources acquisition. Hence, optimizing crop root characteristics has considerable implications for agricultural production. This study evaluated a panel of twenty-eight European modern cultivars of oilseed rape (Brassica napus L.) cultivated in laboratory and field environments. Root morphology was screened using a high-throughput hydroponic growth system ... -
In-Field Observation of Root Growth and Nitrogen Uptake Efficency of Winter Oilseed Rape
10 janvier 2020, HE CondorcetCARAHArticle scientifiqueField trials were conducted with two nitrogen applications (0 or 240 kg N ha−1) and three modern cultivars of winter oilseed rape (Brassica napus L.) previously selected from a root morphology screen at a young developmental stage.

Quel comportement de développement adoptent les rameaux de la vigne après une gelée printanière ?
29 avril 2021, HE CondorcetCARAHArticle scientifiqueL'épisode gélif que nous avons connu en ce début avril nous rappelle combien la météo peut impacter les cultures, notamment fruitières et viticoles. Un tel phénomène s'est également produit l'année dernière, en mai, alors que les vignes se trouvaient à un stade particulièrement sensible de leur développement. À cette occasion, le Carah a observé et analysé comment les différents cépages de son ...
