In bacteriology, gram-positive bacteria are bacteria that give a positive result in the Gram stain test, which is traditionally used to quickly classify bacteria into two broad categories according to their type of cell wall.
Pseudomonadota is a major phylum of Gram-negative bacteria. The renaming of several prokaryote phyla in 2021, including Pseudomonadota, remains controversial among microbiologists, many of whom continue to use the earlier name Proteobacteria, 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 (non-parasitic) and include many of the bacteria responsible for nitrogen fixation.
Acidobacteriota is a phylum of Gram-negative bacteria. Its members are physiologically diverse and ubiquitous, especially in soils, but are under-represented in culture.
The Burkholderiales are an order of Pseudomonadota. Like all Pseudomonadota, they are Gram-negative. They include several pathogenic bacteria, including species of Burkholderia, Bordetella, and Ralstonia. They also include Oxalobacter and related genera, which are unusual in using oxalic acid as their source of carbon. Other well-studied genera include Alcaligenes, Cupriavidus, Achromobacter, Comamonas, Delftia, Massilia, Duganella, Janthinobacterium, Polynucleobacter, non-pathogenic Paraburkholderia, Caballeronia, Polaromonas, Thiomonas, Collimonas, Hydrogenophaga, Sphaerotilus, Variovorax, Acidovorax, Rubrivivax and Rhodoferax, and Herbaspirillum.
The 1908 United States House of Representatives elections were held for the most part on November 3, 1908, with Oregon, Maine, and Vermont holding theirs early in either June or September. They coincided with the 1908 United States presidential election, which William Howard Taft won. Elections were held for all 391 seats of the United States House of Representatives, representing 46 states, to serve in the 61st United States Congress.
The 1904 United States House of Representatives elections were held for the most part on November 8, 1904, with Oregon, Maine, and Vermont holding theirs early in either June or September. They coincided with the election to a full term of President Theodore Roosevelt. Elections were held for 386 seats of the United States House of Representatives, representing 45 states, to serve in the 59th United States Congress.
The 1900 United States House of Representatives elections were held for the most part on November 6, 1900, with Oregon, Maine, and Vermont holding theirs early in either June or September. They coincided with the re-election of President William McKinley. Elections were held for 357 seats of the United States House of Representatives, representing 45 states, to serve in the 57th United States Congress. Special elections were also held throughout the year.
The Alteromonadales are an order of Pseudomonadota. Although they have been treated as a single family, the Alteromonadaceae, they were divided into eight by Ivanova et al. in 2004. The cells are straight or curved rods. They are motile by the use of a single flagellum. Most of the species are marine.
The 1882 United States House of Representatives elections were held for the most part on November 7, 1882, with five states holding theirs early between June and October. They occurred during President Chester A. Arthur's term. Elections were held for 325 seats of the United States House of Representatives, representing 38 states, to serve in the 48th United States Congress. They were the first elections after reapportionment following the 1880 United States Census, increasing the size of the House. Special elections were also held throughout the year.
The 1914 United States Senate elections, with the ratification of the 17th Amendment in 1913, was the first time that all seats up for election were popularly elected instead of chosen by their state legislatures. And thus it became the first time that they were generally scheduled on Election Day to coincide with the U.S. House elections. The 32 seats of Class 3 were contested in regular elections in 1914. Special elections were also held to fill vacancies. These elections occurred in the middle of Democratic President Woodrow Wilson's first term.
The Gemmatimonadota are a phylum of bacteria established in 2003. The phylum contains two classes Gemmatimonadetes and Longimicrobia.
In taxonomy, Rhodothalassium is a genus of the Rhodobacteraceae. Up to now there is only one species of this genus known.
The Chloroflexota are a phylum of bacteria containing isolates with a diversity of phenotypes, including members that are aerobic thermophiles, which use oxygen and grow well in high temperatures; anoxygenic phototrophs, which use light for photosynthesis ; and anaerobic halorespirers, which uses halogenated organics as electron acceptors.
The Selenomonadales are an order of bacteria within the class Negativicutes; unlike most other members of Bacillota, they are Gram-negative. The phylogeny of this order was initially determined by 16S rRNA comparisons. More recently, molecular markers in the form of conserved signature indels (CSIs) have been found specific for all Selenomonadales species. On the basis of these markers, the Selenomonadales are inclusive of two distinct families, and are no longer the sole order within the Negativicutes. Several CSIs have also been found specific for both families, Sporomusaceae and Selenomonadceae. Samples of bacterial strains within this order have been isolated from the root canals of healthy human teeth.
Erythrobacteraceae is a bacterium family in the order of Sphingomonadales.
Pseudopontixanthobacter confluentis is a Gram-negative, aerobic and non-motile bacterium from the genus Pseudopontixanthobacter which has been isolated from the Yellow Sea in Korea.
Pseudopontixanthobacter sediminis is a Gram-negative, non-spore-forming and non-motile bacterium from the genus of Pseudopontixanthobacter which has been isolated from lagoon sediments from the coast of Korea.
Emcibacteraceae is a family of bacteria.
The Temperatibacteraceae are a family of bacteria.
The Holophagae is a class of Acidobacteriota.
