Bohemic acid

Bohemic acid is a mixture of chemical compounds which is obtained through fermentation by actinobacteria species in the Actinosporangium genus (Actinoplanaceae). The name honors the Puccini opera La Bohème and many individual components of the acid carry the names of characters from La Bohème. Most of those components are antitumor agents and anthracycline antibiotics active against Gram-positive bacteria.
