ABSTRACT:
This invention relates to novel microbial strains which produce phenylalanine ammonia-lyase. These novel microbial strains have the ability to grow on minimal essential media which contain, as substantially the sole carbon source, L-tyrosine. Also disclosed are methods for making phenylalanine ammonia-lyase and methods for making phenylalanine.
