Abstract

SUMMARY: The metabolism of methoxylated aromatic compounds by the soil fungi sp., sp. and sp. has been investigated. A study of rates of decomposition of mono-methoxybenzoic acids by sp. revealed that they are most rapidly attacked in the order (), () and (). In respiration studies with all three fungi the form was again found to be metabolized most rapidly. In the initial stage of attack the methoxyl group is replaced by a hydroxyl group. sp. also formed -methoxyphenol from -methoxybenzoic acid. A study of the rates of metabolism of monohydroxybenzoic acids revealed that they are attacked in the same order as the monomethoxybenzoic acids, -Hydroxybenzoic acid formed from -methoxybenzoic acid is further metabolized to protocatechuic acid by sp. and sp. When veratric acid (3:4-dimethoxybenzoie acid) is incubated with sp. and sp. the methoxyl group in the position is replaced by a hydroxyl group to give vanillic acid. All three fungi formed two unidentified phenolic compounds from 2:4-dimethoxybenzoic acid. The possible significance of the results in the decomposition of lignin in soil is discussed.
