Beneficial Prokaryote – Pseudomonas putida

Pseudomonas putida is a gram negative and non-pathogenic bacterium with rod shape. It is usually grow in soil and water which high in oxygen content at 25-30°C. It has mutlitrichious flagella for mobility and it is sensitive to environment changes. Pseudomonas putida has several important strains which are F1 and KT2440 and a few significant plasmids such as the TOL and OCT plasmid. Besides that, it has a circular genome where around eighty genes in oxidative reductase can be found. All these three components found in Pseudomonas putida are important in bioremediation such as degrade toluene and in the application to biotechnology. Pseudomonas putida plays an important role in degradation of pollutants in environment. It has the ability to produce Poly-3-hydroxyalkanoates (PHA) from aromatic hydrocarbon styrene, which is a major environment toxic pollutant produced from industries and is known causes spinal tract irritation, muscle weakness and narcosis in human and mammals. The PHA produced by Pseudomonas putida important in medical applications such as tissue engineering and also as antibiotics and vitamins. Furthermore, PHA can be used in making disposable items such as spoon, fork and other plastic utensils. In addition, it converts styrene oil into biodegradable plastic which is environmental friendly for us. Moreover, Pseudomonas putida is able tolerate to environment stresses due to its diverse control in protein such as protein modification and repair and protein folding and stabilization. This also enables it to function in biofilm production. Besides, Pseudomonas putida acts as an agent for plant growth and plant pest control. The complex interaction between Pseudomonas putida and Saccaromyces cerevisiae together regulate plant health. It is a mutualism between the prokaryotes and the plant. This is because prokaryotes produce sideospores such as pyoverdine and pyochelin to protect the plant from fungal...
