Abstract
In the present study a consortium of four naturally isolated bacterial strains was evaluated as remediation tool for simultaneous removal ofphenol and Cr (VI) from tannery effluent. Application of bacterial consortia to effluent (pH 4.6) resulted in 100 and 78% removal of initial 47mg L-1 phenol and 16 mg L-1 Cr (VI), respectively at 96 h of treatment. The consortium was also active in removal of contaminants with lowerremoval rate in presence of extraneous higher concentrations of both phenol and Cr (VI). Treatment in static mode also resulted in removal ofpollutants, however with increase in agitation speed simultaneous reduction of contaminants becomes faster. Overall it can be inferred fromthe study that the above formulated bacterial consortium could effectively be used for treatment of phenol and Cr (VI) laden tannery and otherindustrial effluents.DOI: http://dx.doi.org/10.3126/ijasbt.v3i1.11889 Int J Appl Sci Biotechnol, Vol. 3(1): 50-55
Highlights
Tannery is one of the oldest industries which deal with processing of animal skin and hide for manufacture of leather
Simultaneous removal of phenol and Cr (VI) from wastewater Mother culture prepared as described above was inoculated to 50 mL of tannery wastewater sample taken in 250-mL Erlenmeyer flask, followed by incubation at 30°C and 200 rpm for 96 h
The tannery effluent especially originating from tanning processes contains a huge quantity of pollutants including organic matter, phenolics, tannins, and chromium and possesses serious health and environmental threats (Chandra et al, 2011; Bhattacharya et al, 2014)
