Abstract

The increased use of ionic liquids in industry has led to the study of their biodegradability and toxicity to prevent contamination of the environment by these synthetic compounds. A Fusarium strain was isolated and tested for its ability to tolerate and grow in the presence of [bmim] [PF6], a potential contaminant of wastewaters. The Fusarium strain was able to grow in both surface and submerged liquid media using [bmim] [PF6] as the sole carbon source up to 19 and 21 g [bmim] [PF6] L–1, respectively. A membrane–aerated biofilm reactor was used for biodegradation studies of synthetic wastewaters. Up to 80% biodegradation was observed after 28 days of incubation at 30 °C. This is the first time that [bmim][PF6] has been subjected to fungal biodegradation.

Keywords: ionic liquids, [bmim][PF6] biodegradation, Fusarium, membrane–aerated biofilm reactor.

 

Resumen

El uso creciente de líquidos iónicos en la industria conduce a estudios de bio–degradabilidad y toxicidad para prevenir la contaminación del medio ambiente por estos compuestos sintéticos. Se aisló una cepa de Fusarium y se probó su habilidad para tolerar y crecer en presencia de [bmim] [PF6], un contaminante potencial de aguas residuales. La cepa de Fusarium fue capaz de crecer tanto en cultivo superficial y sumergido utilizando [bmim] [PF6] como única fuente de carbono hasta 19 y 21 g [bmim] [PF6] L–1, respectivamente. Se utilizó un reactor de biopelícula de membrana aireada para los estudios de biodegradación de aguas residuales sintéticas. Se observó una biodegradación del 80% después de 28 días de incubación a 30 °C. Ésta es la primera vez que se estudia la biodegradación de [bmim][PF6] con hongos filamentosos.

Palabras clave: líquidos iónicos, biodegradación de [bmim][PF6], Fusarium, eactor de biopelícula de membrana aireada.
