Bacterial functional redundancy along a soil reclamation gradient

Article Abstract:

Results show that the response of the bacteria to carbon sources in the soil samples, collected from a soil reclamation gradient, manifests in terms of an increase in the number and diversity of the bacteria, which exhibit highest functional redundancy for the substrates found in the preserved forest soil.

Respiration of (sup)13C-labeled substrates added to soil in the field and subsequent 16S rRNA gene analysis of (sup)13C-labeled soil DNA

Article Abstract:

This article discusses the development of a field soil biodegradation radioisotopic assay to identify individual population of microorganisms mediating the biodegradation of the labeled compounds. The method is based on the analysis of 16S rRNA genes in soil-derived labeled DNA.

Culture-independent identification of microorganisms that respond to specified stimuli

Article Abstract:

Researchers describe a way to identify microorganisms directly in soil samples without culturing them. This is important because fewer than 1% of all microorganisms known to man can be cultured.
