abstract：:Endogenous respiration of spores of the fungus Myrothecium verrucaria can be stimulated up to over-10 fold by diverse chemicals or by physical treatments. Greatest effects were caused by azide (12-fold at 250 mum) and by 2,4-dinitrophenol (7-fold at 300 mum). Marked stimulation was also caused by 10 mum silver (5-fold...
