Aislamiento e Identificación de Hongos filamentosos tolerantes a aceites dieléctricos usados y los Bifenilos Policlorados (PCBs) de suelos contaminados

Abstract

Los PCB´s por sus propiedades físicas y químicas son usados en diferentes sectores industriales; los productos de desechos y almacenamientos inadecuados han contaminado ambientes como suelos y aguas poniendo en peligro la supervivencia en los ecosistemas. Sin embargo, algunos seres vivos son capaces de adaptarse. Los bifenilos policlorados (PCB´s) son compuestos orgánicos de hidrocarburos sintéticos formado por dos anillos de benceno unidos por un enlace de carbono, comprenden una clase de 209 compuestos individuales, isómeros y congéneres. Su objetivo fue el aislamiento e identificación de hongos filamentosos capaces de tolerar y adaptarse para sobrevivir en condiciones adversas en el ecosistema suelo contaminado por el xenobiótico PCB´s, presente en aceites dieléctricos usados (ADU) en un sector industrial de Barranquilla. Los hongos aislados de los géneros Aspergillus sp, Alternaría sp, Phoma sp, Rhizopus sp. sobrevivieron a concentraciones de ADU 20%, y a 200 ppm de PCB´s.
