Mitorubrin derivatives on ascomata of some talaromyces species of ascomycetous fungi
Two groups, producers of (+)- and (-)-mitorubrin derivatives, coexist in the series Lutei of the genus Talaromyces. The optical rotations of mitorubrins from T. emodensis, T. hachijoensis, and T. wortmannii var. sublevisporus, which produced mitorubrinol acetate (5), were all positive, whereas those from T. austrocalifornicus and T. convolutus, which produced mitorubrinal (3) and mitorubrinic acid (4), were all negative.
