Klebsiella sp FIRD 2, a TBT-resistant bacterium isolated from contaminated surface sediment along Strait of Johor Malaysia

摘要

A possible tributyltin (TBT)-degrading bacterium isolated from contaminated surface sediment was successfully identified as Klebsiella sp. FIRE) 2. It was found to be the best isolate capable of resisting TBT at a concentration of 1000 mu g L-1. This was a concentration above the reported contaminated level at the sampling station, 790 mu g L-1 Further studies revealed that the isolate was Gram negative and resisted TBT concentrations of up to 1500 mu g L-1 in a Minimal Salt Broth without the addition of any carbon source within the first 48 h 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.
