Intense Aeration

Azotobacter chroococcum (ATCC 7493) was grown in continuous culture with intense vortex aeration (stirring rate 1750 rpm) with up to 50% O2 in the gas phase. Under these conditions the dissolved O2 generally remained at zero while the cell growth rose to about twice the normally accepted value. The meaning of the term "O2-limitation" in N2-fixing A. chroococcum cultures is critically examined.

A mixture of five saturated 5-n-alkylresorcinol homologues was isolated from vegetative cells of the nitrogen-fixing soil bacterium Azotobacter chroococcum Az12. Their structures were established by spectrometry (1H NMR, EI-MS, FAB-MS, FAB-MS/MS) and chromatography (GC, TLC) means.
