a
All isolates produce several additional unknown secondary metabolites.
b
Production of cycloclavine is uncertain.
c
The isolate produces members of more than three different chromophore families of unknown secondary metabolites.
d
The okaramins produced by A. aculeatus also appear to be okaramins A, B, H, and I (13), but the new species represented by CBS 114.80 is a particularly good producer of these secondary metabolites.
e
CBS 114.80 and CBS 117.55T each produce members of several chromophore families of secondary metabolites that are unique to the isolate.
