Dalam taksonomi, Korarchaeota adalah filum dari Archaea.^[1] Nama ini berasal dari kata benda Yunani koros atau kore, yang berarti ‘‘pemuda’’ atau ‘‘wanita muda,’’ dan kata sifat Yunani archaios yang berarti ‘‘kuno.’’^[2] Mereka juga dikenal sebagai Xenarchaeota.

Analisis sekuens gen 16S rRNA mereka menunjukkan bahwa mereka adalah keturunan sangat bercabang yang tidak termasuk dalam kelompok archaea utama, Crenarchaeota dan Euryarchaeota.^[3] Analisis genom satu Korarchaeota yang diperkaya dari kultur campuran mengungkapkan sejumlah fitur seperti-Crenarchaeota dan Euryarchaeota dan mendukung hipotesis dari keturunan bercabang awal.^[4]

Ekologi

Korarchaeota hanya ditemukan di lingkungan hidrotermal. Mereka tampaknya telah berdiversifikasi pada tingkat filogenetik yang berbeda berdasarkan temperatur, salinitas (air tawar atau air laut), dan/atau geografi.^[5] Korarchaeota ditemukan di alam dalam jumlah yang sedikit.^[5]^[6]^[7]

Setiap mata air panas ini (searah jarum jam dari kiri atas: Uzon4, Uzon7, Uzon8, Uzon9, Mut11, Mut13) di Kamchatka ditemukan mengandung Korarchaeota.^[5]
