Scopelophila cataractae, known as “copper moss,” can grow in areas contaminated with high concentrations of copper where other plants cannot grow. Because it grows more slowly than other plants, its high copper tolerance and ability to accumulate copper are effective survival strategies. These characteristics are also expected to be applied to phytoremediation, which is an environmental regeneration technology. However, in order to study S. cataractae in detail and use it for phytoremediation, it is necessary to culture moss on a large scale, and it is essential to search for media additives that improve the moss growth. Therefore, we focused on Kampyo (dried gourd shavings), which promotes the initial growth of Pohlia flexuosa and Racomitrium japonicum. The growth effect on S. cataractae by adding Kampyo powder to the medium was evaluated. Results indicated that the addition of Kampyo powder to the medium improved the growth of the protonemata of S. cataractae.
