Reduced rumen methanogenesis could be linked to the role of sheanut tannins in reducing protozoa and/or methanogenic archea
population (Bhatta et al.
Scientists say they suspect the Antarctic waters are supersaturated with oxygen and other gases and may be home to bacteria and single-celled microorganisms called archea
These bacteria are metabolically more versatile than the archea
and their enzymatic activity is more diverse [2,21].
In 1995, this program was used to find genes in the first completely sequenced genomes of bacteria and archea
Proteases from different pathogenic organism like protozoa, fungi and archea
were selected for predicting their 3-D structures.

20 As Lovelock has argued with great persuasion, it is only because of bacterial activity on a planetary scale that conditions hospitable to life have been preserved for and beyond the 3 billion years in which only bacteria and archea
(another group of single-celled organisms) were the only living organisms on the planet.

Deep-sea communities comprised by members of Archea
had to resort to terrestrial instead of solar energy with reduced sulfur compounds becoming the major electron donors for aerobic microbial metabolism, thus evading the corrosive effects of the newly generated "pollutant.
Recent work has suggested that in at least some archea
, the specific translation initiation mechanism depends on whether the gene in question is located internal to an operon or is an isolated gene or the first gene in an operon (Tolstrup et al.
Scientists identified a thermostable hydrolizing enzyme, b-glycosidase, from genetically modified hyperthermophilic Archea
Sulfolobus solfataricus and Pyrococcus furiosus that grew in continuous fermentors.
