Abstract

CHANAGA VERA, Xiomara; PLACIDO ESCOBAR, Jersson; MARIN MONTOYA, Mauricio  and  YEPES PEREZ, María del Socorro. NATIVE FUNGI WITH INDUSTRIAL DYE DEGRADING POTENTIAL IN THE ABURRÁ VALLEY, COLOMBIA. Rev. Fac. Nac. Agron. Medellín [online]. 2012, vol.65, n.2, pp.6811-6821. ISSN 0304-2847.

Abstract. Synthetic dyes have stable chemical structures that hinder their treatment by conventional physicochemical processes. In recent years, as a biotechnological alternative for degradation of these recalcitrant compounds, wood degrading fungi of different taxonomic groups have been used. These fungi produced enzymes with oxidative potential for those molecules. The isolation and identification of ligninolytic fungi with potential for discoloration is promising for bioremediation of effluents from textile industries. In this research, we identified four native fungi isolated from lignocellulosic material in the Aburra Valley (Antioquia, Colombia). Identification was made based on sequence analysis of ITS1-ITS2 regions and 28S rDNA as well as morphological characteristics. The fungi were identified as the ascomycete Leptosphaerulina sp., and the anamorphic species Trichoderma viride (two strains) and Aspergillus niger.

Keywords : Biorremediation; decoloration; ligninolytic fungi; sequencing.
