Fitotoxicidad de aguas residuales biorremediadas en Phaseolus vulgaris

Abstract

CONDITION FOR PUBLICATION OF PROJECT. The textile industry generates effluents with high levels of synthetic dyes, posing a significant risk to the environment and agriculture. This project aims to evaluate the phytotoxicity of textile wastewater treated with the bacterial strain C6 in Phaseolus vulgaris, hypothesizing that bioremediation will reduce the toxicity of the effluent, allowing for safe reuse. The justification lies in the need for sustainable and cost-effective alternatives for treating textile wastewater. The project was developed in a 600 mL bioreactor, using synthetic wastewater contaminated with Coomassie Brilliant Blue R-250. After 13 days of incubation with the strain C6, the treated effluent was applied at a concentration of 10% in germination and growth bioassays of P. vulgaris, under controlled conditions. The results showed a degradation of 72.43% of the dye, and the treated effluent exhibited effects comparable to distilled water in terms of germination, chlorophyll, and dry biomass. It is concluded that the effluent treated through bioremediation constitutes a viable alternative for agricultural reuse, aligning with sustainability criteria and mitigating environmental impacts.
