Plant Cell Technology

or reduces microbial contamination in plant tissue culture. At optimum doses, PPM™, does not impair in vitro seed germination, callus proliferation or callus regeneration. Despite the most stringent use of sterile techniques and aseotic conditions, the contamination of plant cell and plant tissue cultures remain a persistent problem. PPM™ prevents the germination of both bacteria and fungi spores. Because it's heat stable, it can be autoclaved with media. PPM™ can be used as a standard ingredient in plant tissue culture media. PPM is less expensive than antibiotics and can prevent fungal contamination simultaneously. PPM is both biostatic and biocidal. In addition to inhibiting airborne, waterborne and human contact contamination, it also can be used to reduce endogenous contamination.
