Effects of organic nutrients and growth factors on biostimulation of tributyltin removal by sediment microorganisms and Enterobacter cloacae

Tributyltin (TBT) contamination of harbour environments, through release from ship antifouling systems, is a global problem. Traditional remediation, via dig and dump, is expensive and environmentally damaging. This is the first paper to demonstrate enhanced in-situ bioremediation of TBT contaminated sediments through optimisation of nutrient/growth factor additions. The work has formed the basis of a Strathclyde Links funded project with Greensolutions (Robert Quigley r.quigley@ecomeshsystems.biz) and British Waterways (Olivia Lassiere, Olivia.lassiere@britishwaterways.co.uk) to demonstrate biostimulation of natural remediation in field trials to improve the effectivess of approach taken to TBT remediation.
