  • Materials and methods for production of bacteria
    Patent number: 7067299
    Abstract: The subject invention provides novel and advantageous methods for growing bacteria. The methods of the subject invention are particularly advantageous for growing parasitic bacteria in vitro, without the presence of host tissue. In one embodiment of the subject invention, Pasteuria endospores, such as those that infect the rootknot nematode Meloidogyne arenaria or other host nematodes, are grown in vitro under acidic conditions. The process of the subject invention is highly advantageous because Pasteuria can be grown in the absence of nematode tissue.

  • Compositions and methods for controlling nematodes
    Patent number: 5595748
    Abstract: The subject invention concerns pest-control compositions and advantageous methods of using these compositions. More specifically, this invention relates to the use of tannins (tannic acid and other analogues, congeners, derivatives, or salts of tannic acid) to control plant-parasitic nematodes. Tannins can be used as nematicides or as nematode-attractants.
