A possible tributyltin (TBT)-degrading bacterium isolated from contaminated surface sediment was successfully identified as Klebsiella sp. FIRD 2. It was found to be the best isolate capable of resisting TBT at a concentration of 1000μgL−1. This was a concentration above the reported contaminated level at the sampling station, 790μgL−1. Further studies revealed that the isolate was Gram negative and resisted TBT concentrations of up to 1500μgL−1 in a Minimal Salt Broth without the addition of any carbon source within the first 48h of incubation. It is expected that additional work could be conducted to check the degradation activity of this new isolate and possibly improve the degradation capacity in order to contribute to finding a safe and sustainable remediation solution of TBT contamination.
