Abstract

The effect of different concentrations of CO2 on the germination of conidiospores of Aspergillus niger A5 has been studied using Pardee's buffer mixtures which maintain constant CO2 tensions. The beneficial effect of CO2 on germination is maximum at 0.5% CO2 concentration, when 70-90% of the spores germinate within 6 hours, whereas in controls with air containing 0.03% CO2 there is only 15-20% germination at 6 hours. At higher CO2 concentrations this beneficial effect of CO2 on germination diminishes and at 3% there is a complete inhibition of spore germination. The spore density and the ph of the medium have a noticeable effect on germination rates in presence of 0.5% CO2. The germination rates decrease at spore densities higher than 5·105/ml and at a ph of 6.8.
