| Abstract: | Harmful algal blooms are a serious worldwide environmental problem. Algicidal microorganisms, especially bacteria, have attracted extensive attention as possible agents for inhibiting water blooms. Such capabilities, however, are rarely reported for fungi. In this work, a fungal strain, Trichaptum abietinum 1302BG, is studied for its capability to inhibit four phytoplankton species: Microcystis aeruginosa FACH-918, Microcystis flos-aquae FACH-1028, Oocystis borgei FACH-1108, and Microcystis aeruginosa PCC 7806. The results show that the chlorophyll-a from these phytoplankton species co-cultured with Trichaptum abietinum 1302BG decreases rapidly 24 h after inoculation, and phytoplankton cells almost completely disappear 48 h after incubation. These results suggest that the fungus strain has great potential for the degradation of phytoplankton species. To the best of our knowledge, this is the first report of a white-rot fungus that can inhibit harmful algae blooms species. |
