    Notes: Abstract An extremely thermophilic anaerobic fermentative eubacterium growing at temperatures between 50 and 80°C (opt.: 65°C) was isolated from an Icelandic hot spring. The cells were Gram-negative motile rods, about 1.8 μm in length, and 0.6 μm in width occurring singly and in pairs. About 50% of the cells formed large spheroids at one end similar to Fervidobacterium nodosum. The new isolate H 21 differed from Fervidobacterium nodosum by a 6 mol % higher GC-content of its DNA (41 mol %), its ability to grow on cellulose, and insignificant DNA homology. The lipids of isolate H 21 were similar to that of members of “Thermotogales”. 16S rRNA sequencing of isolate H 21 and Fervidobacterium nodosum indicated (a) that isolate H 21 represents a new species of the genus Fervidobacterium which we name Fervidobacterium islandicum and (b) that the genus Fervidobacterium belongs to the “Thermotogales” branch.

    Notes: Abstract The autotrophic carbon fixation pathway was studied in the thermophilic hydrogen oxidizing eubacterium Aquifex pyrophilus and in the thermophilic sulfur reducing archaebacterium Thermoproteus neutrophilus. Neither organism contained ribulose-1,5-bisphosphate carboxylase activity suggesting that the Calvin cycle is not operating. Rather, all enzymes of the reductive citric acid cycle were found in A. pyrophilus. In T. neutrophilus ATP citrate lyase activity was detected which has not been achieved so far; this finding corroborates earlier work suggesting the presence of the reductive citric acid cycle in this archaebacterium. The reductive citric acid cycle for autotrophic CO2 fixation now has been documented in the eubacterial branches of the proteobacteria, in green sulfur bacteria, and in the thermophilic Knallgas bacteria as well as in the branch of the sulfur dependent archaebacteria.
