Plant Preservative Mixture, also known as PPM, is a powerful biocide against waterborne, endogenous contamination, airborne, fungal contamination and human contact. It is a liquid solution that prevents and reduces microbial contamination in plant tissue culture, and it is an excelent replacement of the antibiotics. It targets and inhibits multiple enzymes, the formation of resistant mutants towards PPM is unlikely. It is used both as a biocide and biostatic compound as a preventative measure.
- Physical form: Solution
- Appearance: Clear, colorless to amber
- pH: 3.8
Store at 4 °C, in a frigde. Do not store it at temperature above 21°C. When diluted in medium, it could be stored at room temeperature for up to a month.
PPM is stable to temperature, and autoclavable. Autoclavated at 1.05 kg/cm2 (15 psi) and 121°C for 20 minutes.
PPM is for research use only.
