Introduction
PPMâ„¢ is a heat stable preservative/ biocide which can be used to effectively prevent or reduces microbial contamination in plant tissue culture.
At optimum doses, PPMâ„¢ , which stands for Plant Preservative Mixtureâ„¢ , is an extremely effective Preservative/ Biocide, yet does not impair in vitro seed germination, callus proliferation and callus regeneration.
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.
PPMâ„¢ prevents the germination of both bacteria and fungi spores. It is heat stable and therefore can be autoclaved with the media.
PPMâ„¢ 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 PPMâ„¢ 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.
