Correlation between oxygen and nitrate availability and biomass production by A. terreus isolate An-4 (Experiments 1 and 4)
Experiment Treatment Nitrate in media (μM) Final biomass in flask (g)
Experiment 1 Aerobic + Nitrate 43.2 (1.7) 11.4 (1.5)
Anaerobic + Nitrate 52.3 (0.5) 1.5 (0.1)
Experiment 4 Aerobic – Nitrate 3.4 (0.1) 2.2 (0.4)
Aerobic + Nitrate 30.6 (2.7) 11.2 (1.0)
Anaerobic – Nitrate 6.6 (0.1) 0.7 (0.1)
Anaerobic + Nitrate 95.4 (8.7) 2.3 (1.8)

Nitrate concentrations are given as the mean (standard deviation) of 6–10 samples taken during the cultivation period. Final biomass is given as the mean (standard deviation) wet weight of three fungal cultures harvested at the end of the cultivation period. The final biomass does not include the (minor) weight of six samples that were taken for protein and ATP analysis in Experiment 4.
