Opis:: Complete nitrogen removal over nitrite (CANON) was used to treat reject water with ammonia concentrations ranging from 70 to 154mg·L-1. Two experimental sequential batch reactors, SBR_A and SBR_B, differed in the time of the reject water inflow (6h40min vs 40min), process temperature (25 vs 29°C), and the number of aeration periods per day (3 vs 6, respectively). Nitrogen removal efficiency was higher in SBR_B (50-90%) than in SBR_A (40-80%). Analysis of total (PCR-DGGE) and active (RT-PCR-DGGE) bacteria revealed that the biodiversity of the bacterial biocenoses, expressed as the Shannon-Wiener Biodiversity Index, was higher in SBR_B (2.75-3.10) than in SBR_A (1.80-2.75).

Opis:: This study compares the diversity of methanogenic Archaeal communities that developed during biogas production in reactors fed with different substrates. Reactor I was fed with silages of maize and of alfalfa and timothy; and Reactor II was fed with these silages plus pig slurry and glycerol as co substrates. The Archaeal community structure was studied using polymerase chain reaction––denaturing gradient gel electrophoresis based on the 16S rRNA gene. In both reactors, Methanosphaerula palustris was most abundant, and species belonging to Methanolinea, Methanoculleus, and Methanotorris were present. Only Reactor I, where the ammonia concentration was lower, had species belonging to Methanospirillum and Methanosarcina. Thus, it appears that addition of pig slurry increased the ammonia concentration, which inhibited the growth of Methanospirillum and Methanosarcina.
