DER ABBAU VON P-HYDROXYBENZOESAURE, PROTOCATECHUSAURE UND GALLUSSAURE IM BODEN

Abstract

The rate of decomposition of the three phenolic acids, p-hydroxybenzoic acid, protocatechuic acid and gallic acid, whose difference is the amount of OH-groups, was investigated in the soil. With the increase in OH-groups increases the rate of microbial decomposition. Gallic acid decomposes faster than protocatecuic acid and this again faster than p-hydroxybenzoic acid.
