Abstract: | When grown on glucose as principal carbon source the culture medium of Polyporus hispidus was found to contain phenolic acids, including p-coumaric and caffeic acids. 14C-Studies indicated that phenylalanine is converted to cinnamic acid as well as to phenylpyruvic acid and tyrosine in cultures. Cell-free preparations of mycelium contained phenylalanine and tyrosine ammonia-lyse activities and were capable of effecting the hydroxylation of cinnamic, p-coumaric and benzoic acids. |
