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.

    PPM is an integral part of my business

    We use PPM everyday in our business’s tissue culture division. A high throughput approach is capped off by PPM cementing the successes and helping convert them to profit. Thanks.

    Fast and Easy

    Quick shipping and amazing customer service as well as competitive pricing. Highly recommended to anyone looking to reduce the contamination possibilities. Opened up my package and they even tossed in a free shirt, only thing I wish is that it would have been a little bigger size so I could rep it out and about.

    Plant Preservative Mixture (PPM) 30 ml

    Adding the recommended amount of heat-stable PPM (2 ml per liter of orchid germination medium) provides assurance that small lots of imported orchid seed received under the USDA APHIS 587 program are more likely to be sown successfully without competing, destructive contamination.

    Mi experiencia con PPM

    Posted by Álvaro Araya López on 19th Jun 2020

    Cuando comence los cultivos invitro en mi casa, tuve que buscar un agente protector que ayudara a evitar la contaminación del medio de cultivo, así fue como di con este maravilloso producto. Lo mejor es que no tienes que abrir tus frascos autoclavados para agregar bactericidas o fungicidas, PPM lo podía autoclavar con el medio y eso fue lo mejor. Soy técnico agrícola profesional y recomiendo totalmente el uso de PPM para el cultivo invitro de plantas.

    I have used PPM for over 6 years now with my lilium tissue culture media and I have had very little contamination with it's use in less than .5%.

    The best in the market

    Posted by Julian Resurreccion on 19th Jun 2020

    I used 4ml on a starting media, and so far i havent gotten any issue. My first try, all my batch grew mold after a week. This time, its been a week and a half and i havent seen any mold in my tissue culture. Also, sjopping around, i find this to be more economical where others are quite pricy. This one does the job and more.would buy again
