Acidobacteria is a phylum of bacteria. Its members are physiologically diverse and ubiquitous, especially in soils, but are under-represented in culture.
Bacillus safensis is a Gram-positive, spore-forming, and rod bacterium, originally isolated from a spacecraft in Florida and California. B. safensis could have possibly been transported to the planet Mars on spacecraft Opportunity and Spirit in 2004. There are several known strains of this bacterium, all of which belong to the Firmicutes phylum of Bacteria. This bacterium also belongs to the large, pervasive genus Bacillus. B. safensis is an aerobic chemoheterotroph and is highly resistant to salt and UV radiation. B. safensis affects plant growth, since it is a powerful plant hormone producer, and it also acts as a plant growth-promoting rhizobacteria, enhancing plant growth after root colonization. Strain B. safensis JPL-MERTA-8-2 is the only bacterial strain shown to grow noticeably faster in micro-gravity environments than on the Earth surface.
Methanosarcina acetivorans is a versatile methane producing microbe which is found in such diverse environments as oil wells, trash dumps, deep-sea hydrothermal vents, and oxygen-depleted sediments beneath kelp beds. Only M. acetivorans and microbes in the genus Methanosarcina use all three known metabolic pathways for methanogenesis. Methanosarcinides, including M. acetivorans, are also the only archaea capable of forming multicellular colonies, and even show cellular differentiation. The genome of M. acetivorans is one of the largest archaeal genomes ever sequenced. Furthermore, one strain of M. acetivorans, M. a. C2A, has been identified to possess an F-type ATPase along with an A-type ATPase.
Mycobacterium immunogenum is a species of the phylum Actinobacteria, belonging to the genus Mycobacterium.
Pseudomonas balearica is a Gram-negative, rod-shaped, nonfluorescent, motile, and denitrifying bacterium. It is an environmental bacterium that has been mostly isolated from polluted environments all over the world. Many of the isolates have demonstrated capabilities to degrade several compounds. Some of the strains are naphthalene degraders and one strain isolated in New Zealand has demonstrated the potential to oxidize inorganic sulfur compounds to tetrathionate. Based on 16S rRNA analysis, P. balearica has been placed in the P. stutzeri group.
Desulfosporosinus is a genus of strictly anaerobic, sulfate-reducing bacteria, often found in soil.
CandidatusScalindua wagneri is a Gram-negative coccoid-shaped bacterium that was first isolated from a wastewater treatment plant. This bacterium is an obligate anaerobic chemolithotroph that undergoes anaerobic ammonium oxidation (anammox). It can be used in the wastewater treatment industry in nitrogen reactors to remove nitrogenous wastes from wastewater without contributing to fixed nitrogen loss and greenhouse gas emission.
Variovorax paradoxus is a gram negative, beta proteobacterium from the genus Variovorax. Strains of V. paradoxus can be categorized into two groups, hydrogen oxidizers and heterotrophic strains, both of which are aerobic. The genus name Vario-vorax and species name para-doxus (contrary-opinion) reflects both the dichotomy of V. paradoxus metabolisms, but also its ability to utilize a wide array of organic compounds.
Desulfitobacterium hafniense is a species of gram positive bacteria, its type strain is DCB-2T..
Oceanobacillus iheyensis is a bacterium, the type species of its genus. It is a deep-sea species, having been isolated from a depth of 1,050 metres (3,440 ft), and is extremely halotolerant and alkaliphilic. Its type strain is HTE831. Oceanobacillus iheyensis HTE831 is an alkaliphilic and extremely halotolerant Bacillus-related species isolated from deep-sea sediment.
Desulfocapsa sulfexigens is a mesophilic, anaerobic, gram-negative bacterium. It disproportionates elemental sulfur and thiosulfate. SB164P1 is its type strain.
Alcanivorax pacificus is a pyrene-degrading marine gammaprotobacterium. It is of the genus Alcanivorax, a group of marine bacteria known for degrading hydrocarbons. When originally proposed, the genus Alcanivorax comprised six distinguishable species. However, A. pacificus, a seventh strain, was isolated from deep sea sediments in the West Pacific Ocean by Shanghai Majorbio Bio-pharm Technology Co., Ltd. in 2011. A. pacificus’s ability to degrade hydrocarbons can be employed for cleaning up oil-contaminated oceans through bioremediation. The genomic differences present in this strain of Alcanivorax that distinguish it from the original consortium are important to understand to better utilize this bacteria for bioremediation.
Novosphingobium pentaromativorans is a species of high-molecular-mass polycyclic aromatic hydrocarbon-degrading bacterium. It is Gram-negative, yellow-pigmented and halophilic. With type strain US6-1T. Its genome has been sequenced.
Streptomyces xinghaiensis is a bacterium species from the genus of Streptomyces which has been isolated from marine sediments from Xinghai Bay near Dalian in China.
Oceanobacillus is a Gram-positive, rod-shaped and motile bacteria genus from the family of Bacillaceae with a peritrichous flagella.
Marinobacter santoriniensis is a Gram-negative, facultatively anaerobic, non-spore-forming and motile bacterium from the genus of Marinobacter which has been isolated from hydrothermal sediments in Santorini in Greece. Marinobacter santoriniensis can metabolize arsenate and arsenite.
Altererythrobacter is a bacterial genus from the family of Erythrobacteraceae.
Cyclobacterium is a mesophilic, neutrophilic, chemoorganotrophic and aerobic bacterial genus from the family of Cytophagaceae. Cyclobacterium bacteria occur in marine habitats
Shimwellia blattae is a species of bacterium, one of two in the genus Shimwellia. It is an aerobic enteric bacterium first isolated from the hindgut of cockroaches. Although it is related to human pathogens, including Escherichia coli, S. blattae is not pathogenic to humans. It is notable for its ability to synthesize vitamin B12 de novo.
Corynebacterium alimapuense is a species of bacteria in the genus Corynebacterium that was described as a novel speciers in 2019. It is a Gram positive, non-motile, aerobic bacterium that does not form spores. Its type strain was isolated from marine sediment from Valparaíso Bay, Chile. The draft genome sequence is deposited in DNA Data Bank of Japan, European Nucleotide Archive and GenBank under the accession number PTJO00000000.
