摘要:
A process for the production of 17-oxosteroids by fermentative oxidation of 17.beta.-hydroxy steroids is described, which is characterized in that for the fermentation, a bacterial culture of the species Mycobacterium spec. NRRL B-3805, Mycobacterium spec. NRRL B-3683, Mycobacterium phlei NRRL B-8154 or Mycobacterium fortuitum NRRL B-8153 is used.
摘要:
A process for the production of .beta.-carboline derivatives of general formula I ##STR1## in which X represents a hydrogen atom or a halogen atom,Y represents a carbon-oxygen bond or a methyl group,R.sub.1 represents an alkyl group with up to 6 carbon atoms andR.sub.2 represents an alkyl group with up to 4 carbon atoms,from 1,2,3,4-tetrahydro-.beta.-carboline derivatives of general formula II ##STR2## in which X, Y, R.sub.1 and R.sub.2 have the above-mentioned meaning, is described, which is characterized in that the 1,2,3,4-tetrahydro-.beta.-carboline derivatives are fermented with a fungi culture of genus Fusarium or Myrothecium.
