L’objectif principal de ces travaux est d’étudier le devenir des micropolluants organiques dans les sols de plusieurs ouvrages de gestion des eaux pluviales et d’observer l’interaction entre les populations microbiennes et la biodégradation des micropolluants. Trois sites ont été sélectionnés pour étudier ce devenir avec comme critères de choix des...
[ES] El presente trabajo se centra en la fracción orgánica de los residuos, es decir, los biorresiduos. Esta puede ser tratada mediante compostaje y/o metanización con el objetivo de obtener fertilizantes para la agricultura o biogás para generar energía, evitando así su almacenamiento en vertederos. La cuestión que se nos plantea es cómo recoger y...
Growing concern regarding non-biodegradable plastics and the impact of these materials on the environment has promoted interest in biodegradable plastics. Biodegradable plastics offer additional waste management options (e.g., anaerobic digestion or composting) over conventional plastics. However, the treatment of biodegradable plastics under anaer...
Due to the rapid increase of the world population and wastes generated by humans, landfills are filling quickly. Pollution is also increasing due to excessive use of non-renewable resources, and these resources are depleting as well. It is therefore important to invest and work on renewable and environment-friendly resources. To address these issue...
Deadwood is a large global carbon store with its store size partially determined by biotic decay. Microbial wood decay rates are known to respond to changing temperature and precipitation. Termites are also important decomposers in the tropics but are less well studied. An understanding of their climate sensitivities is needed to estimate climate c...
Lignocellulosic biomasses have some characteristics that hinder their use as fuel. Further, the biodegradation processes that can occur during storage can affect their energy properties. Torrefaction can improve their energy properties while reducing the impacts of storage. Near-infrared (NIR) spectroscopy could be a promising tool to estimate chan...
Lignocellulosic biomass is hardly degraded during anaerobic digestion. Among a large panel of pretreatments used to improve the biodegradability of this substrate, alkaline pretreatments are recognized as the most efficient to remove lignin and therefore improve the methane production of these substrates. This article uses different histological st...
Aflatoxin B1 is a potent carcinogen produced by Aspergillus flavus, mainly during grain storage. As pre-harvest methods are insufficient to avoid mycotoxin presence during storage, diverse curative techniques are being investigated for the inhibition of fungal growth and aflatoxin detoxification. Streptomyces spp. represent an alternative as they a...
The amount of carbon stored in deadwood is equivalent to about 8 per cent of the global forest carbon stocks. The decomposition of deadwood is largely governed by climate with decomposer groups—such as microorganisms and insects—contributing to variations in the decomposition rates. At the global scale, the contribution of insects to the decomposit...
The use of wastewater in agricultural sector for irrigation and fertilization purposes is not a recent practice. However, until the past couple decades this practice has been of increasing interest regarding the global safety, particularly human health. Besides to the useful nutrients and organic matter that wastewater introduces to the agricultura...
