Exiguobacterium Undae
''Exiguobacterium undae'' is a species of ''Bacilli''. Its discovery was published in the ''International Journal of Systematic and Evolutionary Microbiology'' (Frühling et al., 2002). This species has the ability to metabolize arabinose, cellulose, fructose, and glucose. It may undergo fermentation by utilizing D-glucose, D-mannitol, D-ribose, and glycogen (Bacdive 2021). ''E. undae'' is motile and it contains peritrichous flagella. Physiology ''E. undae'' was first sampled from the surface of a garden pond in Wolfenbuttel, Lower Saxony, Germany (Frühling et al., 2002). The pond water containing this species was streaked by researchers onto glucose sulfide (GS) medium (DSMZ 851). Four strains, L1-L4, were acquired from the garden pond and successfully isolated in tryptone soy agar at room temperature (Frühling et al., 2002). ''E. undae'' is a Gram-positive, rod-shaped bacterium that is motile and yellow-orange in color (Bacdive 2021). It is facultatively anaerobic and catalas ...

Bacillaceae
Bacillaceae, from Latin "bacillus", meaning "little staff, wand", are a family of gram-positive, heterotrophic, rod-shaped bacteria that may produce endospores. Motile members of this family are characterized by peritrichous flagella. Some Bacillaceae are aerobic, while others are facultative or strict anaerobes. Most are not pathogenic, but ''Bacillus'' species are known to cause disease in humans. Gram-variable cell wall Some Bacillaceae, such as the genera '' Filobacillus, Lentibacillus,'' and '' Halobacillus'', stain Gram-negative or Gram-variable, but are known to have a Gram-positive cell wall.Lim, J.M., Jeon, C.O., Song, S.M., and C.J. Kim. 2005''Pontibacillus chungwhensis gen. nov., sp. nov., a moderately halophilic Gram-positive bacterium from a solar saltern in Korea'' Int. J. Syst. Evol. Microbiol. 55:165-170. Nomenclature Taxa within this family are sometimes colloquially identified as "bacilli". However, this term is ambiguous because it does not distinguish ...

Bacteria Described In 2002
Bacteria (; : bacterium) are ubiquitous, mostly free-living organisms often consisting of one Cell (biology), biological cell. They constitute a large domain (biology), domain of Prokaryote, prokaryotic microorganisms. Typically a few micrometres in length, bacteria were among the first life forms to appear on Earth, and are present in most of its habitats. Bacteria inhabit the air, soil, water, Hot spring, acidic hot springs, radioactive waste, and the deep biosphere of Earth's crust. Bacteria play a vital role in many stages of the nutrient cycle by recycling nutrients and the nitrogen fixation, fixation of nitrogen from the Earth's atmosphere, atmosphere. The nutrient cycle includes the decomposition of cadaver, dead bodies; bacteria are responsible for the putrefaction stage in this process. In the biological communities surrounding hydrothermal vents and cold seeps, extremophile bacteria provide the nutrients needed to sustain life by converting dissolved compounds, suc ...
