Statistical analysis of denaturing gel electrophoresis (DGE) fingerprinting patterns.
The main content focuses on statistical strategies for analysing the gel patterns, from single band examination to the analysis of whole fingerprinting profiles, which make the DGE fingerprinting technique a promising tool. Expand
Molecular detection of anammox bacteria in terrestrial ecosystems: distribution and diversity
The detection of anammox sequences of Candidatus ‘Brocadia’, ‘Kuenenia”, ’Scalindua’ and ‘Jettenia’ in marshes, lakeshores, a contaminated porous aquifer, permafrost soil, agricultural soil and in samples associated with nitrophilic or nitrogen-fixing plants suggests a higher diversity of anlammox bacteria in terrestrial than in marine ecosystems.

An experimental test of the hypothesis of non-homeostatic consumer stoichiometry in a plant litter-microbe system.
The results indicate that P in dissolved form is a major driver of terrestrial microbial stoichiometry, similar to aquatic environments, and the demonstrated relative plasticity in microbial C : P and N :-P and the critical role of P have important implications for theoretical modelling. Expand
Pseudomonas brassicacearum sp. nov. and Pseudomonas thivervalensis sp. nov., two root-associated bacteria isolated from Brassica napus and Arabidopsis thaliana.
16S rDNA (rrs) gene sequencing, DNA-DNA hybridization, biochemical characterization and siderophore typing showed that these isolates belong to two different species that are distinct from other species of the genus Pseudomonas, including P. corrugata. Expand
White lupin has developed a complex strategy to limit microbial degradation of secreted citrate required for phosphate acquisition.
The results suggest that white lupin has developed a complex strategy to reduce microbial degradation of the phosphate-solubilizing agents. Expand
Interactive effects of C, N and P fertilization on soil microbial community structure and function in an Amazonian rain forest
The soil microbial community in the studied tropical rain forest and the pro-cessesitdrivesisfinelytuned by the relative availability of C, N and P is concluded, indicating functionally different microbial communities. Expand
Microbial Biodiversity: Approaches to Experimental Design and Hypothesis Testing in Primary Scientific Literature from 1975 to 1999
A systematic analysis of 753 publications randomly sampled from the primary scientific literature from 1975 to 1999 concerning the microbial biodiversity of eight habitats related to water, soil, plants, and food shows a dominant and growing interest in questions concerning the effect of specific environmental factors on microbial biodiversity. Expand
Specific PCR amplification for the genus Pseudomonas targeting the 3' half of 16S rDNA and the whole 16S-23S rDNA spacer.
A PCR protocol was developed for the selective amplification of a segment of the ribosomal RNA operon in Pseudomonas strains that is relevant for a characterisation at the species (16S rDNA) as well as at the infraspecific (ITS1) levels. Expand
Impact of seasonal sediment desiccation and rewetting on microbial processes involved in greenhouse gas emissions
The response to spring desiccation and autumn (rainfall-related) rewetting of sediment microbial functioning was investigated in a Mediterranean seasonal pond. Surface (0–2 cm depth) and subsurfaceExpand
Direct seeding mulch-based cropping increases both the activity and the abundance of denitrifier communities in a tropical soil
Abstract This study evaluated the impact of direct seeding mulch-based cropping (DMC), as an alternative to conventional tilling (CT), on a functional community involved in N cycling and emission ofExpand
