Bacillus horti is a species of Gram-negative alkaliphilic bacillus. Its cells are strictly aerobic rods that produce subterminally located ellipsoidal spores. Its type strain is K13T (= JCM 9943T). [1]
Bacillus is a genus of Gram-positive, rod-shaped bacteria, a member of the phylum Firmicutes, with 266 named species. The term is also used to describe the shape (rod) of certain bacteria; and the plural Bacilli is the name of the class of bacteria to which this genus belongs. Bacillus species can be either obligate aerobes: oxygen dependent; or facultative anaerobes: having the ability to continue living in the absence of oxygen. Cultured Bacillus species test positive for the enzyme catalase if oxygen has been used or is present.
Bacillus coagulans is a lactic acid–forming bacterial species first isolated and described in 1915 by B.W. Hammer at the Iowa Agricultural Experiment Station as a cause of an outbreak of coagulation in evaporated milk packed by an Iowa condensary. Separately isolated in 1935 and described as Lactobacillus sporogenes in the fifth edition of Bergey's Manual of Systematic Bacteriology, it exhibits characteristics typical of both genera Lactobacillus and Bacillus; its taxonomic position between the families Lactobacillaceae and Bacillaceae was often debated. However, in the seventh edition of Bergey's, it was finally transferred to the genus Bacillus. DNA-based technology was used in distinguishing between the two genera of bacteria, which are morphologically similar and possess similar physiological and biochemical characteristics.
Bacillus megaterium is a rod-like, Gram-positive, mainly aerobic spore forming bacterium found in widely diverse habitats. With a cell length of up to 4 µm and a diameter of 1.5 µm, B. megaterium is amongst the biggest known bacteria. The cells often occur in pairs and chains, where the cells are joined together by polysaccharides on the cell walls.
Bacillus halodurans is a rod-shaped, Gram-positive, motile and spore-forming bacterium found in soil. In a genomic comparison with Bacillus subtilis, B. halodurans strain C-125 - originally an unclassified Bacillus strain - was found to contain unique genes and sigma factors that may have aided its adaptation to more alkaline environments.
Fictibacillus arsenicus, also known as Bacillus arsenicus, is a bacterium. It is Gram-positive, motile, endospore-forming, rod-shaped and arsenic-resistant. Its type strain is Con a/3T.
Oceanobacillus chironomi is a bacterium. It is Gram-positive, motile by peritrichous flagella, endospore-forming, halotolerant and facultatively alkaliphilic. The type strain is T3944DT.
Oceanobacillus oncorhynchi is a halotolerant, obligately alkaliphilic bacterium first isolated from the skin of a rainbow trout, hence its name. It is Gram-positive, rod-shaped and motile by peritrichous flagella and produces ellipsoidal spores. The type strain is R-2(T).
Gracilibacillus halotolerans is a Gram-positive, extremely halotolerant bacteria, the type species of its genus. Its type strain is NNT.
Thiomicrospira aerophila is an obligately alkaliphilic and obligately chemolithoautotrophic sulfur-oxidizing bacterium that was previously the type species of Thioalkalimicrobium prior to reclassification in 2017. It was first isolated from soda lakes in northern Russia.
Symbiobacterium thermophilum is a symbiotic thermophile that depends on co-culture with a Bacillus strain for growth. It is Gram-negative and tryptophanase-positive, with type strain T(T). It is the type species of its genus. Symbiobacterium is related to the Gram-positive Firmicutes and Actinobacteria, but belongs to a lineage that is distinct from both.S. thermophilum has a bacillus shaped cell structure with no flagella. This bacterium is located throughout the environment in soils and fertilizers.
Fictibacillus nanhaiensis is a Gram-positive, aerobic, slightly halophilic, facultatively alkaliphilic, rod-shaped, spore-forming snd motile bacterium from the genus of Fictibacillus which has been isolated from an oyster from the Naozhou Island in China.
Fictibacillus solisalsi is a Gram-positive, rod-shaped, halotolerant, alkaliphilic and motile bacterium from the genus of Fictibacillus which has been isolated from saline soil from Shanxi in China.
Alkalihalobacillus is a genus of gram-positive or gram-variable rod-shaped bacteria in the family Bacillaceae from the order Bacillales. The type species of this genus is Alkalihalobacillus alcalophilus.
Alteribacter 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 Alteribacter auranticus.
Heyndrickxia is a genus of Gram-positive rod-shaped bacteria in the family Bacillaceae within the order Bacillales. The type species for this genus is Heyndrickxia oleronia.
Lederbergia 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 Lederbergia galactosidilyticus.
Priestia is a genus of mostly Gram-Positive rod-shaped bacteria in the family Bacillaceae from the order Bacillales. The type species of this genus is Priestia megaterium.
Rossellomorea is a genus of Gram-Positive or Gram-variable staining rod-shaped bacteria in the family Bacillaceae from the order Bacillales. The type species of this genus is Rossellomorea aquimaris.
Siminovitchia is a genus of Gram-Positive or Gram-negative rod-shaped bacteria in the family Bacillaceae from the order Bacillales. The type species of this genus is Siminovitchia fortii.
