摘要: Antiamoebins I, III and XVI as well several others in minor amounts were produced by four strains of the coprophilous fungus Stilbella erythrocephala (syn. S. fimetaria) its natural substrate liquid culture. The total antiamoebin concentration dung was 126-624 microg g(-1) fresh weight, with minimum inhibitory concentrations against most other fungi being at or below 100 mL(-1). Myrocin B, not previously described from erythrocephala, also produced, but only low, nonfungicidal levels (< 5.3 g(-1)). No antifungal substances detected. It is concluded that antiamoebins are responsible for antibiosis colonized erythrocephala.
