Nitrogen Assimilation: Optimization of N-Labelled Azoverdin Production by Azomonas macrocytogenes ATCC 12334.

M Dobisová1, M A Abdallah, P Kyslík.   

Abstract

The effects of various nitrogen sources and of the cultivation time on the biosynthesis of N-labelled azoverdin were studied in batch cultures of Azomonas macrocytogenes ATCC 12334. Growth for 48 h in the presence of ammonium sulfate (0.2 g/liter) resulted in 95% labelling of azoverdin with N. A growth-related synthesis of azoverdin, under both nitrogen-fixing and ammonium-assimilating conditions, was observed.
