Abstract

The impact of non-domestic wastewater (nDWW) on water bodies every day is increased, considering the different pollutants that are entering and these are not regulated, also that the effects of these are not known in the ecosystems. In the case of the pharmaceutical industry, the various products they generate can contribute from non-steroidal anti-inflammatory analgesics (NSAIDs), antihypertensives, hormones, antibiotics, among others; they are being detected in surface waters and it is necessary to create strategies to improve treatment systems and thus reduce their effects on water systems. In this work, the native microorganisms from nDWW of the pharmaceutical industry were used to evaluate their ability to influence the removal of organic matter, working in mixed culture, where it was evidenced that in a 24 hours they could remove 45.82 % of the organic matter measured by the chemical oxygen demand (COD) and at 48 hours 90.59 % removal. The above shows that the use of microorganisms can contribute to the reduction of COD and pollutants in an effective, environmentally friendly and, more efficient way than conventional methods. Besides, the qualities of tolerance to four NSAIDs by 16 morphotypes are evidenced, and how they can be profiled in the future to be potentialized and reach the mineralization of these emerging pharmaceutical pollutants.
