Molecular identification of a Pseudomonas putida strain isolated from Machángara river (Quito-Ecuador) tolerant to carbamazepine

Carbamazepine is a molecule used to treat specific pathologies; however, it has become an emerging contaminant that dangerous the environment. In marine species and humans, causes cytotoxicity, genotoxicity, reproductive disorders, infertility. Thus, this pollutant been subjected conventional wastewater treatment, achieving low purification. Ecuador, only some studies are related contaminants, these show quantification but not treatment. Therefore, implementation of biological techniques necessary. sense, research aimed identify bacteria in water samples from Machangara River with carbamazepine tolerance. Morphological, biochemical, molecular characteristics identified bacteria. The results indicated presence several microorganisms, including molecularly Pseudomonas putida. This was tolerant concentrations 15, 50, 100 mg/L, higher growth at first concentration. information can be valuable treatment investigations. Keywords: carbamazepine, degradation, river,
