Acidobacteria is a phylum of bacteria. Its members are physiologically diverse and ubiquitous, especially in soils, but are under-represented in culture.
The Gemmatimonadetes are a phylum of bacteria established in 2003. The phylum contains two classes Gemmatimonadetes and Longimicrobia.
Pelomonas saccharophila is a Gram-negative soil bacterium. It was originally named Pseudomonas saccharophila in 1940, but was reclassified in 2005 to the newly created genus, Pelomonas. The original strain was isolated from mud.
Deinococcus is one genus of three in the order Deinococcales of the bacterial phylum Deinococcus-Thermus highly resistant to environmental hazards. These bacteria have thick cell walls that give them Gram-positive stains, but they include a second membrane and so are closer in structure to Gram-negative bacteria. Deinococcus survive when their DNA is exposed to high doses of gamma and UV radiation. Whereas other bacteria change their structure in the presence of radiation, such as by forming endospores, Deinococcus tolerate it without changing their cellular form and do not retreat into a hardened structure. They are also characterized by the presence of the carotenoid pigment deinoxanthin that give them their pink color. They are usually isolated according to these two criteria. In August 2020, scientists reported that bacteria from Earth, particularly Deinococcus bacteria, were found to survive for three years in outer space, based on studies conducted on the International Space Station. These findings support the notion of panspermia, the hypothesis that life exists throughout the Universe, distributed in various ways, including space dust, meteoroids, asteroids, comets, planetoids or contaminated spacecraft.

Collimonas pratensis is a bacterium of the genus Collimonas in the Oxalobacteraceae family which was isolated with Collimonas arenae from seminatural grassland soils in the Netherlands. C. pratensis grows in meadow soils.
Exiguobacterium is a genus of bacilli and a member of the low GC phyla of Firmicutes. Collins et al. first described the genus Exiguobacterium with the characterization of E. aurantiacum strain DSM6208T from an alkaline potato processing plant. It has been found in areas covering a wide range of temperatures (-12 °C—55 °C) including glaciers in Greenland and hot springs in Yellowstone, and has been isolated from ancient permafrost in Siberia. This ability to survive in varying temperature extremes makes them an important area of study. Some strains in addition to dynamic thermal adaption are also halotolerant, can grow within a wide range of pH values (5-11), tolerate high levels of UV radiation, and heavy metal stress.

Massilia lurida is a Gram-negative and rod-shaped and motile bacterium from the genus Massilia which has been isolated from soil from the Inner Mongolia Autonomous Region in China.
Brachybacterium is a genus of Gram positive, nonmotile bacteria. The cells are coccoid during the stationary phase, and irregular rods during the exponential phase. The genus name comes from Greek word brachy, meaning short, and Latin bacterium, meaning rods, referencing the short rods noted during the exponential phase.
Roseomonas is a genus of Gram negative bacteria. The cells are coccoid rods when viewed microscopically. Certain species are known to be opportunistic infections for humans.
Dyella agri is a Gram-negative bacterium from the genus of Dyella which has been isolated from grassland soil.
