Pseudomonas costantinii is a Gram-negative bacterium that causes brown blotch disease in cultivated mushrooms. [1] It demonstrates hemolytic activity. [2] The type strain is CFBP 5705.
Pseudomonas is a genus of Gram-negative, Gammaproteobacteria, belonging to the family Pseudomonadaceae and containing 191 validly described species. The members of the genus demonstrate a great deal of metabolic diversity and consequently are able to colonize a wide range of niches. Their ease of culture in vitro and availability of an increasing number of Pseudomonas strain genome sequences has made the genus an excellent focus for scientific research; the best studied species include P. aeruginosa in its role as an opportunistic human pathogen, the plant pathogen P. syringae, the soil bacterium P. putida, and the plant growth-promoting P. fluorescens, P. lini, P. migulae, and P. graminis.
Halomonadaceae is a family of halophilic Proteobacteria.
Pseudomonas agarici is a Gram-negative soil bacterium that causes drippy gill in mushrooms. It was first isolated in New Zealand. P. agarici could not be grouped based on 16S rRNA analysis, so it is designated incertae sedis in the genus Pseudomonas.
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 tolaasii is a species of Gram-negative soil bacteria that is the causal agent of bacterial blotch on cultivated mushrooms. It is known to produce a toxin, called tolaasin, which is responsible for the brown blotches associated with the disease. It also demonstrates hemolytic activity, causing lysis of erythrocytes. Based on 16S rRNA analysis, P. tolaasii has been placed in the P. fluorescens group.
Pseudomonas moraviensis is a Gram-negative soil bacterium. It is named after Moravia, the region of the Czech Republic where it was first isolated. The type strain is CCM 7280T.
Pseudomonas extremorientalis is a Gram-negative, saprotrophic, fluorescent bacterium found in a drinking water reservoir near Vladivostok City, Russia. The type strain is LMG 19695.
Pseudomonas thermotolerans is a Gram-negative, aerobic, rod-shaped bacterium found in the industrial cooking water of a cork-processing plant. It is capable of surviving at 47 °C (117 °F), hence its name. The type strain is DSM 14292.
Pseudomonas grimontii is a Gram-negative, rod-shaped, fluorescent, motile bacterium isolated from natural springs in France. The type strain is CIP 106645.
Pseudomonas mosselii is a Gram-negative, rod-shaped, bacterium clinically isolated in France. Based on 16S rRNA analysis, P. mosselii has been placed in the P. putida group.
Pseudomonas salomonii is a Gram-negative bacterium that infects garlic. The type strain is CFBP 2022.
Pseudomonas palleroniana is a Gram-negative bacterium that infects rice. The type strain is CFBP 4389.
Pseudomonas trivialis is a fluorescent, Gram-negative bacterium isolated from the phyllosphere of grasses. The type strain is DSM 14937.
Pseudomonas poae is a fluorescent, Gram-negative bacterium isolated from the phyllosphere of grasses. The type strain is DSM 14936.
Pseudomonas congelans is a fluorescent, Gram-negative bacterium isolated from the phyllosphere of grasses. The type strain is DSM 14939.
Pseudomonas umsongensis is a Gram-negative, non-spore-forming, motile, single polar-flagellated, yellow-white, rod-shaped bacterium isolated from the soil in the Umsong region of Korea. The type strain is LMG 21317.
Pseudomonas mediterranea is a bacterium, similar to P. corrugata, that causes tomato pith necrosis. For the phylogenetic analysis of P. corrugata and its closely related phytopathogenic bacterium Pseudomonas mediterranea refer to Trantas et al. 2015.
Pseudomonas indica is a Gram-negative, butane-using bacterium first isolated in India. The type strain is MTCC 3713.
Pseudomonas infection refers to a disease caused by one of the species of the genus Pseudomonas.
Brown blotch disease is a bacterial infection that affects nearly every species of mushroom. The infecting bacteria, Pseudomonas tolaasii, produces the toxin tolaasin that causes brown spots to cover the surface of the mushroom. Brown blotch disease is especially problematic on common mushroom farms, where it can spread quickly and cause huge economic losses.
