Practiced Gram negative bacteria from dyeing industry effluents snub metal toxicity to survive
Isolation and characterization of metal-tolerant bacteria from dyeing industry effluent was the prime drive of the present investigation. Results yielded during screening and isolation, noted the dominance of bacteria verses fungi; in addition, metal tolerance ability of six out of twenty five bacterial isolates were observed. The six selected isolates were gram’s negative, and were identified as Stenotrophomonas maltophilia UOMGNS116, Pseudomonas sp. UOMGNS216, Pseudomonas stutzeri UOMGNS316, Pseudomonas stutzeri UOMGNS416, Citrobacter freundii UOMGNS516 and Achromobacter sp. UOMGNS616 by 16s rDNA analysis. This investigation also evidenced the varied resistance capabilities by Achromobacter sp. UOMGNS616 and Citrobacter freundii UOMGNS516 against chromium and lead by overproduction of external polysaccharides especially against lead.
