Review article Novel techniques for analysing microbial diversity in natural and perturbed environments
TL;DR: In this paper, DNA was extracted from samples of soils and sediments, and a combination of different molecular methods were used to investigate community structure and diversity in these environments, including both the cultivated and non-cultivated part of the community.
Journal ArticleDOI
Novel techniques for analysing microbial diversity in natural and perturbed environments
TL;DR: Using DNA reassociation analysis, it is demonstrated that bacterial communities in pristine soil and sediments may contain more than 10,000 different bacterial types, indicating that the culturing conditions select for a distinct subpopulation of the bacteria present in the environment.
Journal ArticleDOI
Analysis of bacterial communities in heavy metal-contaminated soils at different levels of resolution
TL;DR: DNA reassociation analysis indicated a dramatic decrease in bacterial diversity in soil bacterial communities studied in soils amended for many years with sewage sludge contaminated with heavy metals to varying extents, and shifts in populations of larger phylogenetic groups of bacteria were largely confirmed.
Journal ArticleDOI
Counterintuitive carbon-to-nutrient coupling in an Arctic pelagic ecosystem

TL;DR: This work shows, in the context of an Arctic pelagic ecosystem, how the fate and effects of added degradable organic carbon depend critically on the state of the microbial food web, and highlights how descriptions of present and future states of the oceanic carbon cycle require detailed understanding.
Journal ArticleDOI
Abundance and diversity of Archaea in heavy-metal-contaminated soils.
TL;DR: Analysis of cloned 16S ribosomal DNA showed close similarities to a unique and globally distributed lineage of the kingdom Crenarchaeota that is phylogenetically distinct from currently characterized cren archaeotal species.
