METHOD FOR THE PRODUCTION OF PHENYLALANINE AMMONIA- LYASE BY FERMENTATION

摘要

METHOD FOR THE PRODUCTION OF PHENYLALANINE AMMONIA-LYASE BY FERMENTATION A method for the production of the enzyme, phenylalanine ammonia-lyase (PAL), by fermentation, wherein the stability and useful life of the enzyme are improved by maintaining PAL-containing media in substantially anaerobic, static conditions. PAL is useful for catalyzing the conversion of t-cinnamic acid and ammonia to Lphenylalanine.
