Pseudomonas chlororaphis is a bacterium used as a soil inoculant in agriculture and horticulture. It can act as a biocontrol agent against certain fungal plant pathogens via production of phenazine-type antibiotics. Based on 16S rRNA analysis, similar species have been placed in its group.
Pseudomonas fragi is a psychrophilic, Gram-negative bacterium that is responsible for dairy spoilage. Unlike many other members of the genus Pseudomonas, P. fragi does not produce siderophores. Optimal temperature for growth is 30 °C, however it can grow between 0 and 35 °C. Based on 16S rRNA analysis, P. fragi has been placed in the P. chlororaphis group.
Pseudomonas avellanae is a Gram-negative plant pathogenic bacterium. It is the causal agent of bacterial canker of hazelnut. Based on 16S rRNA analysis, P. avellanae has been placed in the P. syringae group. This species was once included as a pathovar of Pseudomonas syringae, but following DNA-DNA hybridization, it was instated as a separate species. Following ribotypical analysis Pseudomonas syringae pv. theae was incorporated into this species.
Pseudomonas caricapapayae is a Gram-negative soil bacterium that is pathogenic to plants. It was originally isolated on papaya in Brazil. Based on 16S rRNA analysis, P. caricapapayae has been placed in the P. syringae group.
Pseudomonas corrugata is a Gram-negative, plant-pathogenic bacterium that causes pith necrosis in tomatoes. Based on 16S rRNA analysis, P. corrugata has been placed in the P. fluorescens group. For a more comprehensive phylogenetic analysis of P. corrugata and its closely related phytopathogenic bacterium P. mediterranea, refer to Trantas et al. 2015.
Pseudomonas meliae is a fluorescent, Gram-negative, soil bacterium that causes bacterial gall of the chinaberry, from which it derives its name. Based on 16S rRNA analysis, P. meliae has been placed in the Pseudomonas syringae group. Genotypic characteristics of the causal agent of chinaberry gall were determined by Aeini and Taghavi.
Pseudomonas fulva is a Gram-negative environmental bacterium, originally isolated from rice and commonly associated with rice plants, grains and paddy fields. It is rod-shaped and motile using one to three polar flagella.
Pseudomonas mendocina is a Gram-negative environmental bacterium that can cause opportunistic infections, such as infective endocarditis and spondylodiscitis, although cases are very rare. It has potential use in bioremediation as it is able to degrade toluene. Based on 16S rRNA analysis, P. mendocina has been placed in the P. aeruginosa group.
Pseudomonas anguilliseptica is a Gram-negative bacterium that is pathogenic to fish. It was first isolated from Japanese eels. Based on 16S rRNA analysis, P. anguilliseptica has been placed in the P. aeruginosa group.
Pseudomonas synxantha is a fluorescent rhizosphere bacterium with nematicidal properties. Based on 16S rRNA analysis, P. synxantha has been placed in the P. fluorescens group.
Pseudomonas straminea is a Gram-negative, rod bacterium that includes strains formerly identified as P. ochracea. Based on 16S rRNA analysis, P. straminea has been placed in the P. aeruginosa group.
Pseudomonas aurantiaca is an orange Gram-negative soil bacterium, originally isolated from the rhizosphere soil of potatoes. It produces di-2,4-diacetylfluoroglucylmethan, which is antibiotically active against Gram-positive organisms. It has shown potential for use as a biocontrol agent against plant-pathogenic microbes. Based on 16S rRNA analysis, P. aurantiaca has been placed in the P. chlororaphis group.
Pseudomonas taetrolens is a Gram-negative, nonsporulating, motile, rod-shaped bacterium that causes mustiness in eggs. Based on 16S rRNA analysis, P. taetrolens has been placed in the P. chlororaphis group.
Pseudomonas plecoglossicida is a non-fluorescent, Gram-negative, rod-shaped, motile bacterium that causes hemorrhagic ascites in the ayu fish, from which it derives its name. Based on 16S rRNA analysis, P. plecoglossicida has been placed in the P. putida group.
Pseudomonas orientalis is a Gram-negative, rod-shaped bacterium isolated from spring waters in Lebanon. Based on 16S rRNA analysis, P. orientalis has been placed in the P. fluorescens group.
Pseudomonas migulae is a fluorescent, Gram-negative, rod-shaped bacterium isolated from natural mineral waters in France. This bacterium has also been isolated from endophytic tissues of lodgepole pine trees growing on gravel mining sites with potential to perform biological nitrogen fixation and plant growth promotion. Based on 16S rRNA analysis, P. migulae has been placed in the P. fluorescens group.
Pseudomonas gessardii is a fluorescent, Gram-negative, rod-shaped bacterium isolated from natural mineral waters in France. Based on 16S rRNA analysis, P. gessardii has been placed in the P. fluorescens group.
Pseudomonas rhodesiae is a Gram-negative, rod-shaped bacterium isolated from natural mineral waters. Based on 16S rRNA analysis, P. rhodesiae has been placed in the P. fluorescens group.
Pseudomonas azotoformans is a Gram-negative bacterium that infects cereal grains—especially rice. Based on 16S rRNA analysis, P. azotoformans has been placed in the P. fluorescens group.
'Pseudomonas' carboxydohydrogena is a species of Gram-negative bacteria. Following 16S rRNA phylogenetic analysis, it was determined that 'P.' carboxydohydrogena belonged in the Bradyrhizobium rRNA lineage. It has not yet been further classified.
