Abstract:

In this study, the mycelia of Pestalotiopsis sp. F, one kind of filamentous fungus, was dug away after culture in dark, and then the formation of its pycnidium and the accumulation of carotenoid in its mycelia were induced under blue light. The results showed that the carotenoid accumulation increases following with the increase of irradiation time of blue light at 7.0 μmol/m2·s and 25±1 ℃. Also, the carotenoid accumulation is affected by blue light intensity.

Key words: Pestalotiopsis sp. F, blue light, carotenoid, pycnidium
