Studies on the potential use of Pasteuria penetrans as a biocontrol Pasteuria penetrans and the root‐knot nematode (Meloidogyne spp.). Pasteuria penetrans is a gram-positive, endospore-forming eubacterium that apparently is a member of the Bacillus-Clostridium clade. It is an obligate parasite. When they were subjected to a range of physical and chemical treatments, spores of Pasteuria penetrans showed properties similar to those of other.

The objective of this review is to summarize the current knowledge of the biology, ecology, and biological control potential of P. Phenol and chloroform were added, and the endospores were disrupted using a Pasteuria penetrans FastPrep Bio bead beating instrument.
The samples were extracted with pasteuria penetrans sec pulses at 4.

The phases were separated by centrifugation at 18,g for 10 min. The aqueous phase was further purified with subsequent phenol pasteuria penetrans chloroform extractions.
Endospore DNA was precipitated by adding sodium acetate, pH 4. Endospore DNA concentration was determined fluorometrically. Experiments were repeated pasteuria penetrans for a total of three trials.

Root exudates caused a greater decrease in spore attachment in loamy sand pasteuria penetrans in a sandy loam soil. The sandy loam had higher clay content than the loamy sand, which may have resulted in more adsorption of compounds pasteuria penetrans the root exudates that affect spore attachment.
Results of cucumber microplot trials were not as positive as results of the greenhouse trials on cucumber. The one positive effect of the post-plant liquid treatment, a reduction in Rf compared with seed treatment alone, did occur in cucumber microplots.
The remainder of the data did not indicate enhanced control with addition of the post-plant application. The reduction in efficacy in the microplot trials may be due to increased antagonism from native microbial populations compared with the greenhouse studies.
It may be necessary to reduce native soil microbial populations with a chemical treatment such as chloropicrin in order to optimize nematode control in the field with Pasteuria, but further studies would need to be done to confirm this.
