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 cell wall.
Proteobacteria is a major phylum of gram-negative bacteria. They include a wide variety of pathogens, such as Escherichia, Salmonella, Vibrio, Helicobacter, Yersinia, Legionellales and many other notable genera. Others are free-living (non-parasitic) and include many of the bacteria responsible for nitrogen fixation.
Acetobacter is a genus of acetic acid bacteria. Acetic acid bacteria are characterized by the ability to convert ethanol to acetic acid in the presence of oxygen. Of these, the genus Acetobacter is distinguished by the ability to oxidize lactate and acetate into carbon dioxide and water. Bacteria of the genus Acetobacter have been isolated from industrial vinegar fermentation processes and are frequently used as fermentation starter cultures.
The Thermomicrobia is a group of thermophilic green non-sulfur bacteria. Based on species Thermomicrobium roseum and Sphaerobacter thermophilus, this bacteria class has the following description:
Thermus is a genus of thermophilic bacteria. It is one of several bacteria belonging to the Deinococcus–Thermus group. It includes the following species:
Porphyromonas is a Gram-negative, non-spore-forming, obligately anaerobic and non-motile genus from the family of Porphyromonadaceae. This genus has been found to be part of the salivary microbiome.
Sphingomonas koreensis is a Gram-negative and aerobic bacteria from the genus of Sphingomonas which has been isolated from natural mineral water in Taejon in Korea. Sphingomonas koreensis can cause meningitis on humans.
Hymenobacter is a Gram-negative and non-motile bacterial genus from the family of Flavobacteriaceae.
Arenibacter is a rod-shaped and strictly aerobic genus from the family of Flavobacteriaceae.
Belnapia is a genus of bacteria from the family of Acetobacteraceae.
Porphyrobacter is a Gram-negative and pleomorphic bacteria genus from the family of Sphingomonadaceae. Porphyrobacter have ubiquinone-10 as sole respiratory quinones. Porphyrobacter occur in freshwater environments.
Belliella is a Gram-negative, aerobic, chemoheterotrophic and non-motile bacterial genus from the family of Cytophagaceae.
Cyclobacterium is a mesophilic, neutrophilic, chemoorganotrophic and aerobic bacterial genus from the family of Cytophagaceae. Cyclobacterium bacteria occur in marine habitats
Emticicia is a Gram-negative bacterial genus from the family of Cytophagaceae.
Zobellia is a strictly aerobic genus from the family of Flavobacteriaceae. Zobellia bacteria occur in marine habitats.
Marmoricola is a Gram-positive and chemoorganotrophic bacterial genus from the family of Nocardioidaceae.
Polaribacter is a Gram-negative, heterotrophic, psychrophilic or mesophilic and aerobic bacteria genus from the family of Flavobacteriaceae.
Thalassomonas is a genus of bacteria from the family Colwelliaceae. Thalassomonas bacteria can cause the coral diseases white plague.
Pontibacillus is a Gram-positive, spore-forming and strictly aerobic genus of bacteria from the family of Bacillaceae.
Terribacillus is a Gram-positive and aerobic genus of bacteria from the family of Bacillaceae.
