| 摘要 | A method comprising: (a) enzymatically processing an O-acetylhomoserine (OAHS) fermentation liquor to produce L-methionine and an acetate source; (b) separating at least a portion of said L-methionine from at least a fraction of said acetate source to form separated L-methionine and a residual liquor comprising an acetate-source; and (c) recovering at least a portion of said acetate source from said residual liquor as recovered acetate. | ||

| 主权项 | 1. A method comprising: (a) enzymatically processing an O-acetylhomoserine (OAHS) fermentation liquor to produce a processed liquor comprising L-methionine and an acetate source; (b) separating at least a portion of said L-methionine from at least a fraction of said acetate source to form separated L-methionine and a residual liquor comprising an acetate-source; and (c) recovering at least a portion of said acetate source from said residual liquor as recovered acetate, wherein said separating comprises at least two crystallizations, and wherein isolated crystallized methionine from a second crystallization is dissolved and recycled into a processed liquor of step (a). | ||
