Aislamiento e Identificación de microorganismos de sedimentos y aguas de piscinas camaroneras y su posterior inactivación mediante procesos de oxidación avanzada

Abstract

In the present study the isolation four bacteria obtained from water samples from shrimp farms in the canton Huaquillas, El Oro province and, through molecular analysis of the region 16S rRNA was identified them as Exiguobacterium sp was performed., Bacillus sp, Klebsiella pneumoniae and Vibrio fluvialis ,. inactivating the bacteria Klebsiella pneumoniae was evaluated by advanced oxidation treatment with UV (UV, UV / H2O2, UV / H2O2 / Fe) at different concentrations of hydrogen peroxide (10, 30 and 60 ppm) and irradiation times (0, 16, 26, 36, 46, 56 seconds) at neutral pH. It was determined that the addition of 10 ppm hydrogen peroxide (UV / H2O2) and 10 ppm of hydrogen peroxide with 2 ppm of iron (UV / H2O2 / Fe) were found to be the most effective treatments by allowing greater inactivation less irradiation time. The remaining treatments were less effective inactivation times longer and bacterial clearance rates similar. Advanced oxidation processes in relation to other treatments prove to be an efficient disinfection of shrimp farming technique.
