Abstract

Abstract: Microbial decolourization of textile dyes is cost effective and eco-friendly method. Two bacterial species ( Bacillus cereus and Bacillus flexus ) and one fungal species Aspergillus niger were isolated from the dye spilled soil and identified through biochemical and molecular characterization by gene sequencing. Phylogenetic tree was constructed with blast result of closely related sequences using Mega X software with 500 bootstrap. The phylogenetic tree of isolated species showed great diversity with Bacillus and Aspergillus species. A. niger showed 98% of dye degradation capacity, B. cereus has very poor ability to degrade dye when compared with B. flexus. The sequences of B. cereus (MH299975), B. Flexus (MH299976) and A. niger (MH299977) were submitted to NCBI gene bank for global retrieval.
