Expression of TBTCl-induced periplasmic proteins in a tributyltin chloride resistant marine sediment bacterium Alcaligenes sp.

摘要

Organotins are extensively used in various biocidal preparations and also in industries making PVC pipes, polyurethane foams and other plastic components. They are significantly more toxic than inorganic tins, and eventually reach the environment where they can be harmful to a wide variety of non-target organisms. Attention has been focused on tributyltins which are a highly toxic component of antifouling paints and other biocides. In the aquatic environment, organotins including tributyltins accumulate in the surface microlayer, in sediments, and adsorb on suspended particulates1. When organotin compounds, particularly di- or tri-substituted tins, enter an ecosystem, a portion of the microbial population is killed.
