[The Archaen] was collected at Axial Volcano on the Juan de Fuca Ridge off the coast of Washington and Oregon. Fixing nitrogen at 92 C [198F] smashes the previous record by 28 C [82F], a record held by Methanothermococcus thermolithotrophicus, an archaeon that was isolated from geothermally heated sand near an Italian beach and fixes nitrogen at temperatures up to 64 C [116 F].
The critter is also from close to the good ol’ U S of A as opposed to eurotrash from an Italian beach. Story from Newswise.
