The approach used in this study consisted of isolating bacteria and fungi from the ecosphere of hydrilla and screening them for production of enzymes that can lyse specific plant components. These microorganisms were successively subcultured on restrictive media to enhance their enzyme production and then reintroduced to hydrilla in the hope that their more powerful enzyme systems would enable them to attack plant tissues. The rationale for this approach was prompted by promising work done on Eurasian watermilfoil by Dr. Haim Gunner, University of Massachusetts Amherst.
