Although Phaseolus vulgaris L. is native from the Americas and is currently cultured in diverse areas, very little is known about the diversity of symbiotic nitrogen fixing Rhizobium (mycrosymbiont) in many of those cultures. Therefore, the aim of th

The microbial diversity of five unconnected high altitude (≥ 3800 m a.s.l.) wetlands from the Chilean Altiplano was analyzed by a culture-independent approach, using 16 S rRNA gene sequences of different microbial groups. The wetlands (Chungara Lak

We have studied the distribution and community composition of denitrifying bacteria in the stratified water column and at the sediment–water interface in lakes Plußsee and Schöhsee, and a near-shore site in the Baltic Sea in Germany. Although env

Enhanced nitrification and coupled denitrification in macrophyte root zones may contribute to the depletion of nitrogen from the rhizosphere and are both critical processes for agriculture and rhizoremediation. We examined one factor likely to affect

The community composition of ammonia-oxidizing bacteria (AOB) was studied during four stages of plant development in soil cultivated with Phaseolus vulgaris in comparison to unplanted soil, using an alfisol previously harboring the legume Medicago sa

The functional gene amoA was used to compare the diversity of ammonia-oxidizing bacteria (AOB) in the water column and sediment-water interface of the two freshwater lakes Plusssee and Schohsee and the Baltic Sea. Nested amplifications were used to i

The diversity of Cyanobacteria in water and sediment samples from four representative sites of the Salar de Huasco was examined using denaturing gradient gel electrophoresis and analysis of clone libraries of 16S rRNA gene PCR products. Salar de Huas

Over recent years, several PCR primers have been described to amplify genes encoding the structural subunits of ammonia monooxygenase (AMO) from ammonia-oxidizing bacteria (AOB). Most of them target amoA, while amoB and amoC have been neglected so fa

Citrobacter freundii strain WA1 was stressed by incubation in seawater microcosms for eleven years. After two years of starvation, no culturable strain was observed. Incubation of samples in nutrient-rich broth medium not supplemented with growth fac

The bacterial community composition in small streams and a river in central Germany was examined by temperature gradient gel electrophoresis (TGGE) with PCR products of 16S rRNA gene fragments and sequence analysis. Complex TGGE band patterns suggest
