Activated carbon can serve as an additive for a medium - for the absorption of exudates such as polyphenols. These are released into the medium, especially by cutting wounds, and can be toxic when enriched.
Activated carbon is not water-soluble and is present in the medium as a suspension. With time, particles sink despite the fine particle size. Media with activated carbon should be mixed again after autoclaving in order to achieve a more even distribution during hardening. Shortly before pouring, this can be done by inverting the laboratory glass - slowly to avoid foam formation.
Activated carbon not only binds undesirable organic substances - vitamins and growth regulators can also be bound. It may be necessary to adjust the concentrations.
