The objective of this research was to evaluate the nitrogen removal performance of vertical Flow constructed wetlands implemented with a bottom saturated layer in the treatment of raw wastewater (French system). This research was carried out in two pilot systems over 16 months with different saturation depths (25 cm and 15 cm) to determine the opti...

This in vitro study evaluated the roles of diet type and redox potential in the degradation of linalool, (E)- and (Z)-beta-ocimene, alpha-phellandrene, (-)-beta-pinene, (-)-alpha-pinene, (+)-alpha-pinene, sabinene, and alpha-terpinene when incubated with rumen microflora, and it provided information on the time course of their disappearance. The 9 ...

Life on Earth is sustained by a small volume of soil surrounding roots, called the rhizosphere. The soil is where most of the biodiversity on Earth exists, and the rhizosphere probably represents the most dynamic habitat on Earth; and certainly is the most important zone in terms of defining the quality and quantity of the Human terrestrial food re...
Waterlogged soils are submitted to temporal variations of aeration and aerobic–anaerobic conditions which influence redox conditions and thus element mobility. Cultivated paddy soils, that are an accurate redox-dynamic environment, can be found in Camargue (Rhône deltaic plain, SE France). In order to monitor fast physical and chemical variations i...

Aims: The aim of this research was to investigate the impact of extracellular redox potential (Eh) on amino acid conversion to aroma compounds by Lactococcus lactis that is commonly used as a starter in the cheese industry. Methods and Results: The study was realized in vitro by incubating resting cells of L. lactis in reaction media in which Eh wa...
A sampling and measuring device was set up to measure continuously the pH and the redox potential (Eh) of ruminal content in absence of any gaseous contamination (method 1). It was compared with a conventional suction device in which no precaution was taken to prevent air from coming into contact with the surface of collected samples (method 2). Tw...
When biogas production, methane-content and Redox are measured directly at the fermenter as well as time and amount of substrate input and if all these data are documented online, trends can be visualized. In a dynamic management system the fermentation process is being confronted with variations of substrate load. The dynamic responses of the biol...

The present project is one in a series of research activities supported by the European Commission on the role of humic substances for the long-term safety of nuclear waste disposal. These activities started in the mid eighties within the MIRAGE project (MIgration of RAdionuclides in the GEosphere) with the most recent project being ''Effects of hu...
