Population analysis in a denitrifying sand filter: conventional and in situ identification of Paracoccus spp. in methanol-fed biofilms.

The microbial community of a denitrifying sand filter in a municipal wastewater treatment plant was examined by conventional and molecular techniques to identify the bacteria actively involved in the removal of nitrate. In this system, denitrification is carried out as the last step of water treatment by biofilms growing on quartz grains with methanol as a supplemented carbon source. The biofil...

Indisim-som, an Individual-based Model to Study Short- Term Evolutions of Carbon and Nitrogen Pools Related to Microbial Activity in Soil Organic Matter

This work deals with the implementation of a soil organic matter model in an individual-based modelling framework. The simulator INDISIM-SOM models the dynamics of carbon and nitrogen related to soil organic matter and the soil microbial activity by using a discrete simulation. This simulation model controls the activity of group of microbial cells in a space divided into square cells where amo...

Evolution of the bacterial community during granules formation in denitrifying reactors followed by molecular, culture-independent techniques.

The microbial community in two acetate-fed denitrifying reactors, inoculated with methanogenic sludge, was monitored by 16S rDNA-based methods (SSCP and FISH). Both reactors converged to similar, stable communities. The predominant organisms belonged to the genera Thauera, Paracoccus and Denitrobacter, detected both by molecular and culture-based methods.
