Opportunistic bacteria: Pseudomonas putida

Pseudomonas is a genus that contains over 40 species of bacteria; the genus is divided into five groups of classification. The microbes classified in group 1, the group containing P. putida are true Pseudomonads. P. pudita is an opportunistic human pathogen. Exposed the strains of P.putida bacteria for a long time to biocides and antibiotics may constitute a battery of defense mechanisms regardless of their targets of action. The use of P. putida strains in industrial processes, commercial products or consumer products may explain the high number of these bacterial strains in groundwater in Algeria, an increase can be explained also by an optimal temperature between 25 ° C and 30 ° C and an optimal pH which is between 4 to 8, and that P. putida strains appear to be closely related to P. fluorescens.
