| Abstract/Summary |
The concentration of γ-aminobutyric acid (GABA) in extracts of Trichoderma viride grown on sucrose decreased in an age-dependent manner. GABA also disappeared from mycelium when fungus was transferred to the medium with non-saccharide substrate (citrate). Comparative studies with mycelia of Penicillium simplicissimum and Aspergillus nidulans demonstrated similar development of GABA levels during the cultivation. However, in yeast Saccharomyces cerevisiae the amount of GABA was undetectable under aerobic conditions. Results show that GABA shunt is not only active in filamentous fungi but that it seems to be developmentally regulated.
