Gemmiger is a genus of bacteria from the family of Ruminococcaceae. [1] [6]
Pseudomonadota is a major phylum of Gram-negative bacteria. The renaming of phyla in 2021 remains controversial among microbiologists, many of whom continue to use the earlier names of long standing in the literature. The phylum Proteobacteria includes a wide variety of pathogenic genera, such as Escherichia, Salmonella, Vibrio, Yersinia, Legionella, and many others. Others are free-living (nonparasitic) and include many of the bacteria responsible for nitrogen fixation.
The phylum Bacteroidota is composed of three large classes of Gram-negative, nonsporeforming, anaerobic or aerobic, and rod-shaped bacteria that are widely distributed in the environment, including in soil, sediments, and sea water, as well as in the guts and on the skin of animals.
The Chlamydiota are a bacterial phylum and class whose members are remarkably diverse, including pathogens of humans and animals, symbionts of ubiquitous protozoa, and marine sediment forms not yet well understood. All of the Chlamydiota that humans have known about for many decades are obligate intracellular bacteria; in 2020 many additional Chlamydiota were discovered in ocean-floor environments, and it is not yet known whether they all have hosts. Historically it was believed that all Chlamydiota had a peptidoglycan-free cell wall, but studies in the 2010s demonstrated a detectable presence of peptidoglycan, as well as other important proteins.
The Pseudomonadaceae are a family of bacteria which includes the genera Azomonas, Azorhizophilus, Azotobacter, Mesophilobacter, Pseudomonas, and Rugamonas. The family Azotobacteraceae was recently reclassified into this family.
The class Flavobacteriia is composed of a single order of environmental bacteria. According to Bernardet et al., Flavobacteriia are Gram-negative aerobic rods, 2–5 μm long, 0.3–0.5 μm wide, with rounded or tapered ends that are motile by gliding, yellow colonies on agar, decompose several polysaccharides but not cellulose, G+C contents of 32–37%, and are widely distributed in soil and fresh and seawater habitats. In particular, Flavobacteriia are prominent members of marine biofilms. The type species Flavobacterium aquatile was isolated from a well in Kent, England.
Sphingobacteriia is a taxonomic class composed of a single order of environmental bacteria that are capable of producing sphingolipids. The earlier name Sphingibacteria was changed in 2011.
The order Flavobacteriales comprises several families of environmental bacteria.
Bergey's Manual of Systematic Bacteriology is the main resource for determining the identity of prokaryotic organisms, emphasizing bacterial species, using every characterizing aspect.
Bacterial taxonomy is the taxonomy, i.e. the rank-based classification, of bacteria.
Gemmiger formicilis is a bacterium from the genus Gemmiger. It was initially assigned to the "Pseudomonadota", however 16S rRNA sequencing has led to its reclassification in the Bacillota.
Amphibacillus is a Gram-positive, spore-forming, rod-shaped and facultatively anaerobic genus of bacteria from the family of Bacillaceae. Amphibacillus have a low GC-content.
Oscillospiraceae is a family of bacteria in the class Clostridia. All Oscillospiraceae are obligate anaerobes. However, members of the family have diverse shapes, with some rod-shaped and others cocci.
Singulisphaera is a moderately acidophilic and mesophilic genus of bacteria from the family of Planctomycetaceae.
Lamprobacter is a Gram-negative, rod-shaped and motile genus of bacteria from the family of Chromatiaceae with one known species. The habitat of Lamprobacter bacteria is hydrogen sulfide-containing mud and saline water.
Neobacillus is a genus of rod-shaped bacteria that show Gram-positive or Gram-variable staining. This genus belongs under the family Bacillaceae within the order Bacillales. The type species of Neobacillus is Neobacillus niacini.
Peribacillus is a genus of rod-shaped bacteria that exhibits Gram-positive or Gram-variable staining that belongs in the family Bacillaceae within the order Bacillales. The type species for this genus is Peribacillus simplex.
Mesobacillus is a genus of gram-positive or gram-variable, rod-shaped bacteria in the family Bacillaceae within the order Bacillales. The type species for this genus is Mesobacillus jeotgali.
Ectobacillus is a genus of Gram-positive, rod-shaped bacteria in the family Bacillaceae within the order Bacillales. The type species for this genus is Ectobacillus panaciterrae.
Evansella is a genus of Gram-positive rod-shaped bacteria in the family Bacillaceae within the order Bacillales. The type species for this genus is Evansella cellulosilytica.
Weizmannia is a genus of Gram-Positive rod-shaped bacteria in the family Bacillaceae from the order Bacillales. The type species of this genus is Weizmannia coagulans.
