| formation and destruction of photoinduced paramagnetic centers in melanin-containing fungi. | irradiation of the melanin-containing fungi cladosporium transchelii, its pigmented mutants, stemphyllium ilicis, oidiodendron cerealis, and isolated melanin pigment with uv or visible light leads to an increase in the concentration of paramagnetic centers (pc) in melanin pigments, recorded by the epr technique. differences were established in the reaction of melanin of uv-sensitive and uv-resistant cultures to illumination. paramagnetic centers are generated by a single-quantum mechanism (light ... | 1978 | 223667 |
