Screening, isolation and development of fungal consortia with textile reactive dyes decolorizing capability

Abstract

Five different samples (3 effluent samples and 2 soil samples) were collected from CETP in SIPCOT, Perundurai, Erode District, Tamil Nadu and were serially diluted and cultured. 8 different fungal colonies were isolated. Of these fungal isolates, 4 colonies were selected for their ability to decolorize Reactive Red 120, Reactive Black 5 and Direct Red 81 which are synthetic dyes. These selected isolates were identified as Pleurotus ostreatus, Aspergillus niger, Penicillium simplicissimum and Penicillium chrysosporium. Among the selected isolates, Pleurotus ostreatus revealed the maximum percentage of the reactive dye removal of about 76, 64 and 62% for Reactive Red 120, Reactive Black 5 and Direct Red 8 respectively. Further, Four different fungal consortium (FC) were developed, of which FC1 consisting of Pleurotus ostreatus, Aspergillus niger, Penicillium simplicissimum, Penicillium chrysosporium exhibited the highest dye removal percentage of 78% for Reactive Black 5.
