Understanding „fungal behaviour“ – The excretion of organic acids is an essential property of fungal organisms involving many parts of metabolism. In a recently finished project of the Austrian Science Fund three of these parts - adenine and pyridine nucleotides, alternative respiration, and the plasma membrane H+-ATPase – were studied simultaneously in Penicillium ochrochloron using chemostat culture with different nutrient limitations.
Main conclusions were: (i) proper sampling and applying analytical methods necessitates considering the high phenotypic plasticity of fungal organisms; and (ii) don´t look for an universal explanation – each nutrient limitation is unique.
