Plant Preservative Mixture (PPM™)

Plant Preservative Mixture (PPM™), is a broad-spectrum biocide/fungicide for plant tissue culture. PPM™ is the ultimate solution to the never-ending struggle against microbial airborne, waterborne and endogenous contamination.


The use of PPM™ in the above instances has proven very successful in controlling the microbial contamination levels in our tissue culture programme. Furthermore, with the development of new techniques and protocols, it is reasonable to assume that additional problems with contamination are likely to be encountered. PPM™ will therefore continue to be stocked as a standard consumable item in our laboratory." -- SASRI Tissue Culture Laboratory
