Resumen

La microalga Chlorella sp. fue investigada como material viable para el tratamiento biológico de soluciones del
colorante catiónico azul de metileno (AM). Para esto, se examinó el efecto de diferentes concentraciones iníciales
de microalga, 1,06 x 106 UFC cm-3, 2,16 x 106 UFC cm-3 y 3,30 x 106 UFC cm-3 (0,1, 0,2 y 0,3 unidades de absorbancia
respectivamente), sobre soluciones de 10 mg dm-3 de AM, tanto en presencia como en ausencia de nutrientes. En
todos los casos se presentó remoción del colorante que, según los cambios en los espectros UV-VIS de las soluciones
decoloradas corresponden tanto a procesos de biosorción como de biodegradación. En los ensayos realizados
en presencia de nutrientes se alcanzaron porcentajes de remoción del 84,3 % para concentraciones de microalgas
correspondientes a 0,1 unidades de absorbancia y alrededor del 90 % para concentraciones de microalgas correspondientes
a 0,2 y 0,3 unidades de absorbancia; mientras que, con los ensayos realizados en ausencia de nutrientes
se removieron entre un 98,4 % y 99,4 % del colorante.
