BIOSYNTHESIS OF METHIONINE USING A REDUCED SOURCE OF SULFUR

摘要

The invention relates to methods by fermentation for the synthesis of methionine and homoserine by means of a reduced source of sulfur such as sulfide or methyl mercaptan, and / or by modifying the biosynthetic pathway of methionine in a producing microbe. The invention also relates to methods by fermentation for methionine synthesis and homoserine via a sulfur source such as oxydisée sulfate sulfite or thiosulfate; and / or by modifying the biosynthetic pathway of methionine in a microbe.
