Abstract:
Recent research indicates that siderophores, a class of biogenic ligands with known exceptional affinity for Fe(III), can also strongly complex Co(III), an element essential to normal metabolic function of microbes and animals. This study was conducted to examine the siderophore-promoted dissolution rates and mechanisms of Co from model synthetic Co-bearing minerals to elucidate the role of siderophores in biogeochemical processes of Co. Dissolution of heterogenite (CoOOH) and four Co-goethites (Co-FeOOH) with different levels of Co substitution were investigated in the presence of a trihydrox

Abstract:
A large variety of co-formulants are added to commercial pesticide formulations to enhance their biological effectiveness, but their impacts on the behaviour of active substances are largely unknown due to lack of regulatory measures concerning their use. The overall aim of this research was to investigate the impacts of co-formulants on pesticide sorption and leaching through soil. Leaching and sorption experiments were carried out using technical grade and commercial formulations of four different pesticides at various intervals from application in two soils from the Blackwood and Bishampton

Abstract:
Polycyclic Aromatic Hydrocarbons (PAHs) that are generated by diverse anthropogenic sources, are classified by the U.S. Environmental Protection Agency (EPA) as Semivolatile Hazardous Compounds. PAHs are pollutants of great concern due to their toxicity and mobility in the environment; they can be found in air, water, and soil media. Supercritical Fluid Extraction (SFE) is currently an alternative technology for the removal of PAHs from solid matrices. Carbon dioxide, water and organic compounds, above their critical temperature and pressure conditions, have been used as supercritical fluids

Phosphorus (P) is a nutrient of concern in the Chesapeake Bay watershed due to nutrient imbalances in areas with confined animal feeding operations. By converting poultry litter to an ash via thermal conversion, nutrients are concentrated and are economical to ship out of nutrient surplus watersheds to nutrient deficient regions, such as the corn-belt. We initiated incubation and field studies on sandy loam soils to test P and potassium (K) availability from poultry litter ash (PLA).

Soil microbial communities mediate important ecological processes and play essential roles in biogeochemical cycling.

Abstract:
Global carbon cycle dynamics and fluxes of CO2 between biosphere and atmosphere have been progressed through the use of Keeling Plots. Processes that control and effect the isotopic composition of soil-respired CO2, soil CO2, and equilibrated soil carbonate are specifically addressed in this study through the use of Keeling Plots. Replicate grassland soil profiles containing either C3 or C4 homogenized organic matter were constructed and maintained under controlled settings to encourage the production of soil-respired CO2 and the precipitation of pedogenic carbonate. Soil CO2 was sampled over

Abstract:
Celem pracy była mikrobiologiczna ocena skuteczności higienizacji procesu kofermentacji metanowej. Dokonano oceny wpływu cieczy pofermentacyjnej na właściwości mikrobiologiczne i fizykochemiczne nawożonych gleb. Materiał do badań stanowiły: gnojowica świńska, kiszonka kukurydziana i opcjonalnie odpady mięsne, które poddano procesowi kofermentacji metanowej w warunkach mezo- i termofilnych. Przeprowadzona została analiza wartości nawozowych pofermentu w oparciu o wzrost i plonowanie gorczycy białej. Wykazano różnice w eliminacji drobnoustrojów patogennych i jaj pasożytów A. suum w trakcie przeb

Abstract:
Les virus du sol sont capables d'influencer la structure de la communauté microbienne et le fonctionnement de l'écosystème en affectant l'abondance des cellules hôtes par lyse et par leurs caractéristiques à transférer des gènes entre les hôtes. Bien que notre compréhension sur la diversité et la fonction virales s’améliore, la connaissance des interactions hôte-virus dans le sol reste limitée. Pour mieux comprendre les interactions hôte-virus, un gradient du sol à long terme manipulé par le pH dans lequel la communauté microbienne change à travers, a été étudié. Les principaux objectifs de ce

Abstract:
Ce travail de recherche s'inscrit dans le prolongement de différentes études conduites notamment dans le cadre du pilote de Capture Transport et Stockage du CO₂ (pilote Total CCS, Lacq- Rousse, France) relatives au suivi des mécanismes de transfert des gaz (CO₂ et CH₄) dans les compartiments Géosphère/Biosphère/Atmosphère. De ces études, il était ressorti que l'évolution de la fraction molaire de CO₂ (χc) dans le sous-sol karstique du plateau du Jurançon était négativement corrélée aux battements de la nappe phréatique située à -45m via des mécanismes de dissolution/dégazage. Cependant, il n'e
