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...

Lyophilizatin of 13 cyanobacterial cultures belonging to seven genera was attempted in a variety of suspending substances. All organisms survived lyophilization when suspended in lamb serum. Some of the organisms could be successfully lyophilized in horse serum, beef serum, fetal bovine serum, or human ascites fluid. With the exception of Nostoc muscorium, none of the organisms survived lyophil...

The location o f malate dehydrogenase in the cyanobacteria, Anabaena cylindrica, Nostoc muscorum and Chlorogloeopsis fritsch ii was investigated by the fractionation o f cell-free ex­ tracts. The bulk o f the enzyme activity was associated with the thylakoid membrane fraction, which also exhibited complete photosynthetic electron transport reactions. Malate dehydro­ genase activity and photosys...
