Biodiversity and dye decolourization ability of an acclimatized textile sludge
In the present study, sludge sample from biological treatment plant of a textile industry was acclimatized for decolourization of azo dye Direct Black 38 (DB38). A continuous culture experiment showed that the acclimatized sludge could decolourize 76% of 100 mg/l DB38. Bacterial community in the slu...

Summary: | In the present study, sludge sample from biological treatment plant of a textile industry was acclimatized for decolourization of azo dye Direct Black 38 (DB38). A continuous culture experiment showed that the acclimatized sludge could decolourize 76% of 100
mg/l DB38. Bacterial community in the sludge was analyzed using culture-independent molecular approach to get the complete picture of its diversity. RFLP analysis of its 16S rRNA gene library divided the clones into 14 distinct groups. Phylogenetic analysis of these groups showed that they belonged to five different bacterial lineages: β
- and γ
-Proteobacteria (3 and 4 respectively),
Bacteroidetes (2),
Firmicutes (4) and
Actinobacteria (1). The largest number of clones was found to cluster in the γ
-Proteobacteria (54%), followed by
Firmicutes (19%), β
-Proteobacteria (14%),
Bacteroidetes (10%) and
Actinobacteria (3%). |
