and archaea as exemplified by antibiotic resistance. When a specific bacterium develops a defense against some drug the corresponding gene can pass horizontally to others in the same colony.
He is remembered perhaps best for classifying life into the now-well-accepted domains of bacteria eukaryotes (plants animals fungi and protists) and archaea.
Specifically they will target archaea whose genes have yet to be scrutinized as closely as those from the other domains Goldenfeld said.
They observed certain traits in Archaea that previously only were seen in Bacteria and vice versa. One such trait involves an enzyme that bacteria commonly use for creating space within their protective cell wall
For the first time a group of Archaea was found to encode this potent enzyme and the authors hypothesize that Archaea may deploy it as a defense mechanism against attacking Bacteria.
The second contribution arising from the work was the correct reassignment or binning of data of some 340 million DNA fragments from other habitats to the proper lineage.
The Nature publication Insights into the phylogeny and coding potential of microbial dark matter builds upon a DOE JGI pilot project the Genomic Encyclopedia of Bacteria and Archaea GEBA:
The pink-orange of many salt lakes containing Dunaliella is intensified by the presence of archaea fellow single-celled organisms.**
This research concerns methane-forming archaea a group of microbes known as methanogens which live in areas where oxygen is absent.
