Adaptation and Promotion of in Vitro Growth by Pseudomonas Aeruginosa GU270941.1 A in the Presence of Cadmium

Cadmium (Cd) is one of the most toxic heavy metals. Its high mobility and bioaccumulation power in plant, animal and human tissues differentiate it from the rest of its group and motivate the interest of scientists to know its effects and interaction with plants and the environment. The aim of the present study was to isolate and evaluate the in vitro tolerance of rhizospheric bacteria associated with rice plants in cadmium-contaminated environments and to evaluate them in vitro capacity to tolerate cadmium and the production of compounds related to their ability to remediate and promote plant growth. Rhizospheric bacteria were isolated, tolerance was found up to 500 mg/L CdCl2 and the ability to produce siderophore and solubilize phosphate at this concentration of cadmium was observed in vitro. The morphospecies with the ability to tolerate cadmium up to 500 mg/L found corresponds to Pseudomonas aeruginosa GU270941.1, a species of rhizospheric bacteria that shows an alternative to reduce cadmium uptake by rice plants and promote the growth of these plants for their adaptation and tolerance to this metal.
