It was concluded that the failure of rhodococci to bring about total degradation of chloroaromatics through chlorocatechols is mainly due to the absence in these organisms of a modified ortho‐cleavage pathway (i.e. maleylacetatepathway).

The elucidation of the structures has shown that aklanonic acid and aklanone are derivatives of 1,8-dihydroxyanthraquinone, a yellow-orange crystalline substance having the molecular formula C21H16O8.
Tolypocladin — a new metal-chelating 2-aza-anthraquinone fromTolypocladium inflatum
SummaryA new chelator of di- and trivalent cations (tolypocladin) was isolated from the mycelium ofTolypocladium inflatum DSM 915. The structure has been determined by NMR methods as…

The results of the experiments provided evidence that aklanonic acid very probably is an early intermediate in the biosynthetic pathway of anthracyclines, and its biotransformation by daunorubicin-negative mutants derived from different daunors producing organisms.
