Extracts of Ditylenchus dipsaci were most active in decreasing the viscosity of solutions of pectin N.F., less active towards pectin L.M., and least active towards Na polypectate. Optimum pH for activity of extracts was 6.0 for pectin N.F. and pectin L.M., and 5.0 for Na polypectate. Inorganic ions at a concentration of 0.2-0.3 M greatly increased the rate of reduction in viscosity of pectin N.F. solution by nematode extract. Nematode extracts retained full ability to reduce the viscosity of pectin N.F. solution when heated for 10 minutes at various temperatures through 50° C, but lost 22% of their activity at 60°, 87% at 70°, and 89% at 100°. Galacturonic acid plus several unidentified breakdown products occurred on chromatograms of nematode extract incubated with pectin N.F. solution. When nematode extract was incubated with pectin N.F. solution, reducing groups and end products of pectin trans-eliminase activity were detected in reaction mixtures by spectrophotometric methods.
