Recent studies with Pseudomonas strain 244 have indicated that the volatile methylated species produced by this organism from SnIV, and to a considerably lesser extent from SnII, include tetramethyltin Me4Sn and a number of hydridic methylstannanes MenSnH4-n, n 2, 3. Subsequently, using hydridization coupled with a new purgetrap gas chromatographic method, methylated tin compounds methylstannanes have been found in the Chesapeake Bay, as both volatile and non-volatile species CH3nSnH4-n and CH3nSn4-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.
