The understanding of nitrogen (N) cycling in forest ecosystems has undergone a major shift
in the past decade as molecular methods are being used to link microorganisms to key …

Summary 16S rRNA-targeted oligonucleotide probes for eubacteria (EUB338), ammonium-
oxidizing bacteria (Nsm156) and nitrite-oxidizing bacteria (Nb1000) were used for the rapid …

Nitrification, the oxidation of ammonia via nitrite to nitrate, has always been considered to be
catalyzed by the concerted activity of ammonia-and nitrite-oxidizing microorganisms. Only …

Autotrophic ammonia oxidation occurs in acid soils, even though laboratory cultures of
isolated ammonia oxidizing bacteria fail to grow below neutral pH. To investigate whether …

▪ Abstract An increasing interest has emerged with respect to the importance of microbial
diversity in soil habitats. The extent of the diversity of microorganisms in soil is seen to be …

This review summarizes the microbial mechanisms responsible for removal of carbon,
nitrogen, and sulfur compounds in treatment wetlands (TWs) and identifies, categorizes and …

Phylogenetic surveys of soil ecosystems have shown that the number of prokaryotic species
found in a single sample exceeds that of known cultured prokaryotes. Soil metagenomics …

Nitrous oxide (N 2 O) is mainly generated via nitrification and denitrification processes in
soils and subsequently emitted into the atmosphere where it causes well-known radiative …

Microorganisms play important roles in the nitrogen cycles of various ecosystems. Research
has revealed that a greater diversity of microorganisms is involved in the nitrogen cycle than …

Mesophilic crenarchaeota are frequently found in terrestrial and marine habitats worldwide,
but despite their considerable abundance the physiology of these as yet uncultivated …
