Abstract

The BIOSORPTION of copper (II) from aqueous solution using different BACTERIAL STRAINS was studied. Copper-biosorbing bacteria were isolated from tannery effluent collected from Borg Al-Arab, Alexandria, Egypt. These isolates displayed different degrees of copper BIOSORPTION under aerobic conditions. Based on 16S rDNA gene sequence analysis, three of them (S2, S5 and S7) were identified as Chryseobacterium sp., Enterobacter sp. And Stenotrophomonas sp., respectively. Initial copper (II) ion concentrations from 25-250 mg/L at constant temperature 30°C were studied. The residual copper (II) concentration and its toxicity effect in solution were determined using atomic absorption spectrophotometer and BIOLUMINESCENT bioreporter. The bioluminescence inhibition of strain (S5) reached to 91.4 % as compared with the strain (S7) reached to 83.3 % at 225 mg/L of copper ion where the maximum BIOSORPTION efficiency for S5 and S7 were 71 % and 70.1% correspondingly using atomic absorption. The BIOLUMINESCENT bioreporter was proved to be fast and accurate technique for measurement the toxicity effect of residual copper (II) in solution.
