Plant Preservative Mixture (PPM™)
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.
Coupled with proper observation of aseptic laboratory techniques, PPM™ can increase your chances of a successful and thriving culture experiment.
The Benefits of Plant Preservative Mixture
- 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.
- PPM™ does not affect the genetic profile of the plants.
How To Use Plant Preservative Mixture?
- General Dosage levels:
With the exception of endogenous contamination, the recommended dose range is 0.05%-0.2%. (For callus proliferation, organogenesis and embryogenesis, the recommended range is 0.05-0.075%.) To eliminate higher endogenous contamination densities, higher doses of PPM™ are needed.
- Endogenous Contamination:
(a) For explants: gently and routinely shake / stir 1 cm. long explants (or shorter) for 4-12 hours in 4-5% v/v PPM™ solution supplemented as above with 3x MS
strength basal salts without Tween 20.Without rinsing, insert into a medium supplemented with 0.05 - 0.1% PPM™ for herbaceous plants and 0.2% PPM™ for woody plants.
Note: Paragraphs 6(b) through 10 below are intended for ornamental plants only.
(b)For tubers, bulbs and scales: shake / stir the entire tuber/ bulb / scale in bleach. Rinse with water (can be done under non-sterile conditions). Slice the tuber / bulb /scale to thin slices. Shake / stir for 12-24 hours in 4- 5% PPM™ solution supplemented with full strength basal salts without pH ing & Tween 20. Without rinsing, insert into a medium supplemented with 0.1 -0.2% PPM™.

PPM, is the Ultimate go to for Plant Protection!!!
I am going to use this for my entire culture, trial got very good results, we are running Tissue culture Lab, and its capacity is 3 million plants per qtr. we are supplying to Indian domestic market and US Florida, Miami, Thailand, etc.
I have a professional setup so i don't have problems with contamination, so i don't use PPM all the time. I do back up strains for long term storage and use it for that. I feel safe that if some contamination does find its way into the vessel, that it will not grow.
I use 1.5mL of PPM per liter of MS media for Ribes propagation and have much less contamination issues than without. I use it for all now.
