Plant Preservation Mixture (PPMTM)
broad-spectrum biocide formulated for use in plant tissue culture
- Plant Preservation Mixture (PPM) is a robust broad-spectrum biocide formulated for use in plant tissue culture.
- PPMTM targets bacteria and fungi in plant tissue culture growth media as well as contaminated tissue.
- It affects key enzymes in the Krebs cycle and in the Electron Transport Chain.
- Depending on the dose and the level of contamination, PPM is a biocidal component in plant culture medium.
- In addition, it may also function as a biostatic compound as a preventative measure.
- When diluted with plant growth media it is effective as a microbiocide (i.e. bactericide and fungicide) against non-human health pathogenic organisms component of liquid or semi-solid plant culture media.
- PPMTM is effective for most seed baring plants - angiosperm, as well as gymnosperm,- however, it is not recommended for use in ferns, mosses, algae and aquatic plants. Optimization may be required to maximize potency.
- While PPM is an excellent tool in the prevention and elimination of culture contamination it is not a substitute for asceptic laboratory techniques and appropriate air handling systems are recommended.
What is Plant Preservative Mixture (PPM) ?
Plant Preservative Mixture (PPM), is a broad-spectrum biocide/ for plant tissue culture. PPM™ is the ultimate solution to the never-ending struggle against microbial airborne, waterborne and endogenous contamination.
ABOUT PLANT PRESERVATIVE MIXTURE (PPM)
PPM™ is a heat stable preservative/biocide which can be used to effectively prevent or reduces microbial contamination in plant tissue culture.
At optimum doses, PPM™, which stands for Plant Preservative Mixture™, is an extremely effective Preservative/Biocide, yet does not impair in vitro seed germination, callus proliferation and callus regeneration.
PPM™ prevents the germination of both bacteria and fungi spores. It is heat stable and therefore can be autoclaved with the media.
PPM™ can be, and should be used as a standard ingredient in plant tissue culture media, and is also substantially less expensive than commonly used antibiotics.
While PPM™ was principally designed to inhibit airborne contamination, waterborne contamination and contamination introduced from human contact, it can also -- in many cases -- be used to reduce endogenous contamination.
Despite the most stringent use of sterile techniques, the contamination of plant cell and plant tissue cultures remain a persistent problem that can result in losses ranging from small number of cultures to the loss of whole batches.
