The colonies were isolated onto a medium made of 1.5% Bacto-Agar and a specific trace element solution consisting of MoO 3, ZnSO 4 ·H 2 O, CuSO 4 ·5H 2 O, H 3 BO 3, MnSO 4 ·H 2 O and CoCl 2 ·H 2 O. [4] Prior to the discovery of Hydrogenobacter thermophilus, only one extremely thermophilic, aerobic and hydrogen-oxidizing bacterium had been ...
Bacteria exhibit an extremely wide variety of metabolic types. [101] The distribution of metabolic traits within a group of bacteria has traditionally been used to define their taxonomy , but these traits often do not correspond with modern genetic classifications. [ 102 ]
A microorganism, or microbe, [a] is an organism of microscopic size, which may exist in its single-celled form or as a colony of cells.. The possible existence of unseen microbial life was suspected from ancient times, such as in Jain scriptures from sixth century BC India.
Saccharibacteria, formerly known as TM7, [1] is a major bacterial lineage. It was discovered through 16S rRNA sequencing . [2]TM7x from the human oral cavity was cultivated and revealed that TM7x is an extremely small coccus (200-300 nm) and has a distinctive lifestyle not previously observed in human-associated microbes.

Thermotoga maritima is a hyperthermophilic, anaerobic organism that is a member of the order Thermotogales. T. maritima is well known for its ability to produce hydrogen (clean energy) and it is the only fermentative bacterium that has been shown to produce hydrogen more than the Thauer limit (>4 mol H 2 /mol glucose).

Food microbiology is the study of the microorganisms that inhabit, create, or contaminate food.This includes the study of microorganisms causing food spoilage; pathogens that may cause disease (especially if food is improperly cooked or stored); microbes used to produce fermented foods such as cheese, yogurt, bread, beer, and wine; and microbes with other useful roles, such as producing ...
Thermus aquaticus is a species of bacteria that can tolerate high temperatures, one of several thermophilic bacteria that belong to the Deinococcota phylum. It is the source of the heat-resistant enzyme Taq DNA polymerase, one of the most important enzymes in molecular biology because of its use in the polymerase chain reaction (PCR) DNA amplification technique.
For example, Escherichia coli cells, an "average" sized bacterium, are about 2 μm (micrometres) long and 0.5 μm in diameter, with a cell volume of 0.6–0.7 μm 3. [1] This corresponds to a wet mass of about 1 picogram (pg), assuming that the cell consists mostly of water. The dry mass of a single cell can be estimated as 23% of the wet mass ...
