Materials and methods for the efficient production of Pasteuria
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 spores, such as those that infect the rootknot nematode Meloidogyne arenaria or other host nematodes, are grown in vitro. The process of the subject invention is highly advantageous because Pasteuria can be grown in the absence of nematode tissue.
1. A method for producing Pasteuria endospores in vitro, said method comprising introducing Pasteuria into a growth medium, growing the Pasteuria in said growth medium, and obtaining said endospores, wherein said growth medium comprises a microorganism having all the identifying characteristics of ATCC 2324.
2. The method, according to claim 1 , wherein said growth medium does not comprise an antibiotic.
3. The method according to claim 1 , wherein a compound selected from the group consisting of manganese sulfate and lipids is added to induce the production of endospores.
