Biotransformation of Tin.

Abstract

Recent studies with Pseudomonas strain 244 have indicated that the volatile methylated species produced by this organism from Sn(IV), and to a considerably lesser extent from Sn(II), include tetramethyltin (Me4Sn) and a number of hydridic methylstannanes (Me(n)SnH(4-n), n = 2, 3). Subsequently, using hydridization coupled with a new purge/trap gas chromatographic method, methylated tin compounds (methylstannanes) have been found in the Chesapeake Bay, as both volatile and non-volatile species ((CH3)(n)SnH(4-n)) and (CH3)(n)Sn((4-n)+), respectively). Studies on the biological transformation of organotin compounds have so far indicated that there are no significant bio-transformations of tributyltin moiety, Bu3Sn(+) (TBT). TBT-resistant organisms from the Chesapeake Bay were found to accumulate tributyltin. This accumulation did not appear to be an energy requiring process, since glucose did not significantly stimulate starved cells to accumulate tin.
