Pseudomonas aeruginosa

Pseudomonas aeruginosa is a microorganism characterized by a high capacity for adaptation. It is found in surface water, wastewater, marine water, and in general in all humid environments. It represents one of the microorganisms typical of biofilms.

It is a purely environmental microorganism and therefore also detectable in groundwater and drinking water where it can be found in widely varying concentrations.

In particular, it is easily detectable in conditions of stagnant water and is able to install itself in tanks, tap aerators and domestic equipment for the treatment of drinking water, reaching high bacterial loads.

Generally, P. aeruginosa is detected in chlorinated water when the residual chlorine concentration is less than 1 mg/L. Its presence is generally considered an indicator of poor packaging procedures for water sold in bottles or containers where, if present, it is capable of multiplying*.
