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.

PPM
I am a beginner hobbyist in Plant tissue culture and this PPM has made life so much easier, which a greatly decreased contamination rate. Really quick shipping and super helpful when Ive had questions.

Volume 1 Liter
I buy 1 Liter, but maybe customs officers in Indonesia took 250mL as sample, so I only get 750mL. Well, that's okey. I give 5 stars to seller.

Positive results in emergency situation
I had to unexpectedly flask an orchid green seed capsule with no access to an autoclave, laminar flow cabinet or glove box, I used only rudimentary sterilizing techniques and PPM. No contamination after nearly four weeks. Amazing!

Amazing
So just to test the ability of the PPM to resist microbial contaminants - I dosed two plates of media, one with and one without, with several drops of actively aerated compost tea. In 7 days the plate without PPM was entirely overrun with fungi and bacteria - the plate with PPM has had zero visible growth at 1ml/l. Every culture I have placed in PPM media - has had no problems with unwanted contamination. Some magic stuff here.

PPM
I am very grateful to have found PPM. In the past I was averaging a 70% contamination rate. Since using PPM I'm holding steady at a 5% contamination rate.

Works Perfectly!
I'm new to micropropagation. I was concerned about contaminated cultures. I've use PPM in the first several media batches and all have been contamination-free. For me, PPM is a required ingredient in a media formulation.
