ハクトウワシ

アメリカの国鳥であり保全の成功を象徴するハクトウワシは翼開長が最大2.4 mに達し、北米全域の水辺近くの森林や湿地に生息する。強力な空中捕食者兼腐肉食者で魚を主食とするが、水鳥や腐肉も捕食する。DDT汚染と狩猟によって1960年代にほぼ絶滅に瀕したが、農薬の使用禁止と絶滅危惧種法の施行により劇的に回復した。

Clitopilus passeckerianus is a white-rot agaric fungus in the family Entolomataceae notable for its role as a natural producer of pleuromutilin, a diterpenoid antibiotic compound that serves as the biosynthetic precursor for the veterinary and human antibiotic drugs tiamulin and valnemulin, used to treat Mycoplasma infections in livestock. First described from European woodland habitats, the species produces the characteristic Clitopilus fruiting body: a pale, whitish cap with decurrent, crowded gills becoming pinkish at maturity from angular spores, and a farinaceous odor. Its antibiotic-producing capacity makes C. passeckerianus of significant pharmaceutical interest, and biosynthetic studies of pleuromutilin production have informed synthetic chemistry approaches to antibiotic development. The species inhabits temperate deciduous woodland floors in Europe, fruiting in autumn among leaf litter. Discovery of its pleuromutilin biosynthetic pathway has opened avenues for heterologous expression and semi-synthetic modification aimed at developing novel antibiotics to counter antibiotic-resistant bacterial pathogens.
