Persistence and biological activity in soil of insecticidal proteins from Bacillus thuringiensis and of bacterial DNA bound on clays and humic acids

Authors: Stotzky, G.
Journal, Volume, Year: Journal of Environmental Quality, volume 29:691-705, 2000
Summary

This is a review article discussing much of Stotzky�s previous research. Adsorption and binding of Bt toxins to clay minerals is discussed, as well as the availability of these bound toxins to microbes. In addition, insecticidal activity of Bt toxins, using larvae of tobacco hornworm and Colorado potato beetle, is also discussed. Preliminary studies evaluating the effects of Btk toxins from transgenic corn and rice on gross metabolic activity of soil are also discussed.
