Microbial diversity of Minnesota peatlands

Microbial Ecology, 1983
Microbial diversity, numbers, and metabolic activities in Minnesota peatlands were investigated using a variety of microbial enrichment and enumeration procedures together with radioisotopic measurements of microbial degradative processes. Minnesota peatlands were shown to contain large microbial populations of wide metabolic diversity.

Microbial diversity of soda lakes

Extremophiles, 1998
Soda lakes are highly alkaline extreme environments that form in closed drainage basins exposed to high evaporation rates. Because of the scarcity of Mg2+ and Ca2+ in the water chemistry, the lakes become enriched in CO3(2-) and Cl-, with pHs in the range 8 to > 12. Although there is a clear difference in prokaryotic communities between the hypersaline

Microbial diversity of cellulose hydrolysis

Current Opinion in Microbiology, 2011
Enzymatic hydrolysis of cellulose by microorganisms is a key step in the global carbon cycle. Despite its abundance only a small percentage of microorganisms can degrade cellulose, probably because it is present in recalcitrant cell walls. There are at least five distinct mechanisms used by different microorganisms to degrade cellulose all of which ...

Microbial diversity

2014
Abstract ‘Microbial diversity’ considers the vast array of microorganisms—the smallest forms of life—which exist everywhere. The three primary groups of microorganisms are bacteria, archaea, and eukaryotes. Bacteria and archaea are prokaryotes with their genetic material held in a single chromosome.

The value of microbial diversity

Current Opinion in Microbiology, 1998
In the past few years, due to the use of molecular methods, our knowledge of microbial diversity has increased dramatically, not only from a phylogenetic and taxonomic perspective but also from an ecological basis. We now know that microorganisms exist in every conceivable place on Earth, even in extreme environments.

Microbial diversity – insights from population genetics

Environmental Microbiology, 2007
Summary Although many environmental microbial populations are large and genetically diverse, both the level of diversity and the extent to which it is ecologically relevant remain enigmatic. Because the effective (or long‐term) population size, N e , is one of the parameters

Microbial Genome Diversity and Microbial Genome Sequencing

2019
The role of microbiome in agroecosystems has evolved due to improvements in microbial diversity analysis methods. The journey of microbial diversity estimation progressed from culture-dependent to culture-independent methods. The culture-dependent methods are important in finding the microbial diversity of different environments; however, they are ...

Natural Biotechnology: Exploiting Microbial Diversity

2010
"Water is life!" All active cellular systems require water as the medium and solvent of their metabolic activities. Hydrophobic compounds and structures, which tend to exclude water, though providing inter alia excellent sources of energy and a means of biological compartmentalization, present problems of cellular handling, poor bioavailability and, in

Molecular community analysis of microbial diversity

Current Opinion in Biotechnology, 2002
New technologies that avoid the need for either gene amplification (e.g. microarrays) or nucleic acid extraction (e.g. in situ PCR) have recently been implemented in microbial ecology. Together with new approaches for culturing microorganisms and an increased understanding of the biases of molecular methods, these techniques form the most exciting ...
