effect of some bacterial isolates in bioremediation of Cadmium

This study was conducted with the aim of applying Bioremediation technology in order to identify efficiency some bacterial isolates for improving quality wastewater discharging from a tank Al-Hindiyah district sewage water treatment station Karbala Governorate. The included use bacteria remove heavy metals (Cd), as 120 were isolated before entering and after leaving under study, it appeared that only 6 them tolerant high concentrations up 2,400 mg /L. These diagnosed Api20E technique Vitek2 examination. Four (A49, A35, A15, A1) belongs genus Serratia marcesens isolate A10 Enterobacter aerogenes, while A32 refers Klebsiella pneumonia. ability these tested laboratory experiment removing Severally using biomass isolates, A35 isolation characterized by achieving highest removal rate Cd, reaching 71.399% 72 hours. Also, all very (Cd) metal wastewater, rates 99.415%
