Abstract

Washed mycelial felts of an Alternaria sp. isolated from soil, when grown on a malt extract medium, rapidly metabolized various cinnamic and benzoic acids. The intermediates in the degradation of trans-cinnamic, m-coumaric, p-coumaric, ferulic and sinapic acids have been identified. In vivo studies with ${^1^4}C$-labelled cinnamic acid, p-coumaric acid and benzoic acid have shown that these compounds are converted to p-hydroxybenzoic acid and protocatechuic acid. When the organism was fed with cinnamic $acid-2-^1^4C$, a part of the radioactivity after 6 hr was trapped in glutamic and aspartic acids. These results strongly suggest that Alternaria shortens the cinnamic acid side-chain by $\beta$-oxidation. The organism did not have any detectable levels of phenylalanine and tryosine ammonia-lyase activities.
