High Quality Content by WIKIPEDIA articles! In taxonomy, the Crenarchaeota (Greek for "spring old quality") (also known as Crenarchaea or eocytes) has been classified as either a phylum of the Archaea kingdom or a kingdom of its own. Initially, the Crenarchaeota were thought to be extremophiles (e.g., thermophilic and psychrophilic organisms) but recent studies have identified them as the most abundant archaea in the marine environment. Originally, they were separated from the other archaea based on rRNA sequences; since then physiological features, such as lack of histones have supported this division. However, some crenarchaea were found to have histones. Until recently all cultured Crenarchaea had been thermophilic or hyperthermophilic organisms, some of which have the ability to grow at up to 113 °C. These organisms stain Gram negative and are morphologically diverse having rod, cocci, filamentous and oddly shaped cells.
