TL;DR: The results indicate that the wetland sediments contained organisms such as Geobacter sp.

TL;DR: Examining successional changes in the structure of bacterial assemblages using denaturing gradient gel electrophoresis (DGGE) analysis of polymerase chain reaction amplified 16S rDNA fragments suggested greater equitability in bacterial community structure as the biofilms developed, suggesting that bacterial assembLages may not be structured by the resource competition or niche-driven patterns typical of communities of macroorganisms.

TL;DR: No DNA hybridization was detected with the nahAcgene probe, indicating that enzymes involved in PAH metabolism are not related to the well-characterized naphthalene dioxygenase gene, and a distant relationship between genes involved in alkane oxidation is suggested.

TL;DR: Three different gels were evaluated as a means of removing humic contaminants from DNA extracts of environmental samples and Sepharose 4B gave superior separation of DNA from humics, and DNA purified in this way showed consistently greater amplification than DNA purified by the other materials.

TL;DR: A framework for additional taxonomic revisions within the new order Rhizophydiales is provided and compares genetic variation useful in defining genera, species, and populations within this lineage of chytrids to a broader sampling of representatives is needed before taxonomic decisions can be made for remaining clades within the RhizophYDiales.
