Description 580-588
In
the present study, totally 20 bacterial strains were isolated from two sites of
study area and also screened their tolerance against cadmium (II) ions. Among
the strains, 6 strains were screened as cadmium resistant and remaining 14 strains
as cadmium sensitive. Colony morphology, staining and biochemical test showed that
highly cadmium resistant bacteria (HCRB) NT-1, NT-5, NT-10, TT-5, TT-8 and
TT-10 belongs to Bacillus sp. Enterobacter sp., Aeromonas sp.,
Bacillus sp., Aeromonas sp., and Pseudomonas sp.
respectively. Biosorption potential of HCRB (NT-1, NT-5, NT-10 and TT-10) was
assessed in the 100 mg/l Cd (II) ions containing marine broth. Strain TT-10
showed maximum percentage (99 %) of cadmium removal in CdCl2. 5H2O
treated broth when compared to other resistant isolates. This study infers that

cadmium
resistant bacteria such as Pseudomonas sp. (TT-10) are valuable
candidates for bioremediation of cadmium contaminated ecosystem.
