Biotransformation of AD and ADD using Nostoc muscorum

The potential of microalgae for steroid transformation has been studied less than other microorganisms. They have been applied for the years in the treatment of environmental pollutions and preparation of nutrients. At the first time, Abul-Hajj and Qian indicated the conversion of androstendione (AD) to testosterone with eleven different strains of microalgae. Previtera’s group showed the trans...

Differentiation in Nostoc muscorum: nitrogenase is synthesized in heterocysts.

Cellular differentiation can be observed in certain filamentous blue-green algae after transfer of the cells from medium containing NH(4) (+) or NO(3) (-) to nitrogen-free medium. The appearance of differentiated cells (heterocysts) is accompanied by an increase in the activity of nitrogenase, an enzyme complex that reduces N(2) to NH(3). We have separated vegetative cells from heterocysts in d...
