Pseudomonas teessidea

Pseudomonas teessidea[1] is a species of Pseudomonas bacteria which was first discovered in the North of England. The specific epithet teessidea was given by a microbiologist at Teesside University.[2] Biosurfactant from Pseudomonas teessidea : Surfactants work by reducing surface tension between two liquids or a liquid and a solid. Biosurfactants, surface-active agents of biological origin, have environment-friendly properties; they are bio-degradable, non-toxic and can be made organically using local raw material and producers. Biosurfactants can be used in soaps, detergents, medical ointments or as emulsifiers i.e. within ice cream, facial cream or sun lotion. Pseudomonas teessidea is a new bacterial species which was discovered by Dr. Pattanathu Rahman in the Northeast of England.[3] This bacterium has DNA coding distinct from existing species and has unique properties developed in response to the contaminated soil from which it comes. It produces rhamnolipids type of biosurfactants to detoxify oil and chemicals contaminants in the ground.[4]

Rhamnolipids are predominantly produced by the microbe Pseudomonas aeruginosa. However, Pseudomonas putida is a model organism with greater metabolic versatility and potential for industrial applications. Computational methods for metabolic engineering are able to model and optimise such biological models, leading to the improvement of a given biotechnological pipeline.The engineered genome-scale model of Pseudomonas putida built during a BBSRC Research project [5] can already be used to predict and maximise rhamnolipid production and transport through the cell membrane. The promising results found during this project have strengthened the collaboration between TeeGene and the Computational Biology group at Teesside University. The resulting pipeline will finally be used to build a genome-scale model of Pseudomonas teessidea for which a model is unavailable.[6] The resulting project will elucidate the metabolic engineering steps for overproduction of rhamnolipids and their transport out of the cell membrane.

Biodiversity of Pseudomonas teessidea:

  1. UK: Biosurfactants and Bioemulsifiers[7]
  2. Sweden: There is great concern for the widespread increase of cyanobacterial blooms globally. Blooms can be toxin producers and cause serious health implications for wild life and humans. However, even blooms that are not toxin producers can be detrimental to the environment due to biomass increase, which can cause oxygen depletion that lead to fish death. From a productive lake (Ekoln, basin of lake Mälaren - Sweden) Monica Ricão Canelhas team managed to isolate cyano-lytic bacteria including Pseudomonas teessidea.[8]
