N2  - A quantitative determination method of gallic and protocatechuic acid in cultures and liquid nutrient of Phycomyces blakesleeanus was described. Both phenolic acids were separated by TLC and the colour reaction with Folin reagent was used for a colorimetric test. This procedure was employed for investigating the formation of gallic and protocatechuic acid in cultures with optimal (10-4 m) and reduced (1.3 × 10-6 ᴍ) zinc supply showing that their production is stimulated by zinc ions.
In addition, the inhibiting effect of light on the accumulation of gallic acid was manifested, however, its excretion into the medium was uneffected by light and protocatechuic acid was not excreted at all. During the development of Phycomyces gallic and protocatechuic acid could be detected in two days old mycelium . With the sporangiophore production both acids are accumulated more rapidly in the sporangiophores. After the end of sporangiophore formation the gallic acid content increases only slightly. In contrast the total content of protocatechuic acid decreases sharply. As no excretion occurs a degradation of at least protocatechuic acid must be taken into consideration.
