E. Blochl et al., ISOLATION, TAXONOMY AND PHYLOGENY OF HYPERTHERMOPHILIC MICROORGANISMS, World journal of microbiology & biotechnology, 11(1), 1995, pp. 9-16
Hyperthermophilic Archaea and Bacteria with optimal growth temperature
s between 80 and 110-degrees-C have been isolated from geo- and hydro-
thermally heated terrestrial and submarine environments. 16S rRNA sequ
ence comparisons indicate great phylogenetic diversity among the 23 di
fferent genera represented. Hyperthermophiles consist of anaerobic and
aerobic chemolithoautotrophs and heterotrophs growing at neutral or a
cidic pH. Their outstanding heat resistance makes them as interesting
objects for basic research as for biotechnology in the future.
